HT820 Distortion - JASJAR, XDA Exec, MDA Pro Accessories

HI, recently purchased a pair of HT820 headphones and have noticed a very noticable distortion when operating in BT mode, is there a way around this as its quite noticable when listening to music and people are singing, the beats however are not distorted.
Any help much apreciated, also noticed slight pauses every now and then.

Disortion?
I puchased the same HT-820 the problem is not directly known by me.
Is it possible that your device is out of range or someting
it will disort with
- Iron in the way
- out of range +10 meter
succes with your problem

Hi, when I say distortion I mean kinda like static, i have my device very close about 1ft away, no intereference between me and device, though have noticed that when I pass vehicles or cars drive pass me my sound pauses. it gets annoying, the statics my biggest issue though. tried the fix registry key but it does absolutely nothing what so ever! grrrr!!!!

Several serious problems with Qtek 9090

I'm having several problems with my Qtek 9090
There's a rather loud constant high-pitched noise comming from the screen whenever it is turned on (which is when the device is on!). At first I though it was comming from the speaker, but the screen is definitely the source of the noise. It doesn't matter if the backlight is on or off.
People can't hear what I say when using the phone - it makes no difference whether I use the included headphones or just speak directly into the microphone.
I haven't been able to find a BT headset that works with it. They all have the same problem; The sound scratch so much they're unusable. I tried 3 different brands that all works well with my 2020!
The GSM link often "falls out" - even though there's plenty of link the phone doesn't work (nothing happens when I try to call someone). A soft reset solves this problem!
As you can see, I can hardly use the device as a phone at all I've had the device replaced once, but all the problems persists on the replacement.
Does anyone have similar problems?
1. No, don't have this problem. Strange that it happened on the replacement too.
2. Yes.
3. I have just ordered a jabra headset in the hope it will fix problem#2.
4. Yes.
These problems with GSM are a real headache. One of the primary reasons for buying the PDA2k was to consolidate my mobile into one device. I have seen other people experiencing such problems but from what I could gather, voice over BT worked much better. Have you updated the ROM since you bought it? I should know the answer to 3 today, if DHL delivers, and I can tell you I will not be a happy man if the answer is Yes!
Try a Motorola HS810 headset... works fine for me.

I've already tried Jabra Freespeak 250, which didn't work for me
No I haven't updated the ROM as I've been told by the supplier that no new version is available yet!

I also tried both a Motorola and a SonyEricsson BT headset, but I don't remember the specific models - they both scratched immensely
i use SE 60 and it works ok
As you said, the Jabra250 is pretty much unusable!
Crackling is not constant but goes in waves, even though I do not move.
Am at a bit of a loss what to do now... the device is great apart from this.
>> People can't hear what I say when using the phone - it makes no difference whether I use the included headphones or just speak directly into the microphone
yes PBT read my other post
I have the same problem!!
it is scandalous to sel an device with this big defect!!
Sony HBH-660 works good for me.
People say that they can't hear me when I use the handset, but I don't have any crackling, etc with the headset and voice is clear. You just never know if the headset is going to connect when the phone rings though.

I have this problem also, I was told to use the new rom but this has made no difference, Please let me know if you have found a solution

Guys,
the hissing coming from the screen is a power supply problem. keep swapping phones until it goes away! I used to build switching power supply and the hissing (in a system designed to operate well above 20kHz) is only able to be heared when unstable, inductor core or cap is broken. The hissing is very 'not normal'.
It appears that the Q9090 is standing out as having more problems than the MDAIII, one is the mic volume, most of the other phones are not complaining about this so there may be something with they way the Q9090 are updated or shipped.
With the Jabra 250, don't forget to pair it pressing BOTH the volume and phone button on the headset on discovery with the 9090.(On bonding, turn off headset, turn on again pressing both buttons)
Funny thing is, I had the cracking also. I deleted the headset in BT manager and paired it again as described above. Now it works ok.
Hi,
I bought a Qtek 9090 a few days ago and I also have the same problem with volume level. People can't hear me when speaking, either with the headset or base microphone.
Using a different headset doesn't help (that's even worse sometimes) but I didn't try a BT heaset (and I don't want to as it would raise potential connection problems). I'm going to contact Qtek for support on this...
Pierre
I too am having problems with the Jabra 250 BT headset and my SPV M2000. The Jabra 250 worked fine on the XDAII but is terribly crackly on the newer model.
This is even when pairing it with the enhanced pairing of pressing Volume Up and Phone button together to pair.
Any ideas?
qtek 9090 bluetooth problem
Hi All,
I have new qtek9090 with cellink bluetooth headset. It is work normal, but i am loosing connection to headset each time qtek go to stand by mode. I need to switch off/on the bluetooth in order to restore the connection. Any ideas?
I often get a message stating:
"The Bluetooth Radio failed to turn ON due to insufficient driver momory available. You must perform a normal reset before you can turn ON the Bluetooth Radio."
Does your device also give you this message?
Is it also using the Broadcom "Bluetooth for Windows CE BT-PPC/PE Version 1.0.0 Build 2200"?
Interested to know if you have the same problems with the same bluetooth driver.
same problem
My qtek 9090 shows te same problem
This is a known problem with the Blue Angel, unfortunately, until they bring out a fix, all you can do is a soft reset.
upgrade
hi all,
how can i get updates from www.imateclub.com?
I can't register there, because I have qtek 9090 and not i-mate
thanks

Nosie With A2DP!!!

Hi I'm new to the site, i had read a lot post about upgrading roms from different companys, i read people describe how good the a2dp quilty is, but the problems comes, i first upgraded the rom to T-Mobile , then i found there are a high pitch nosie, at first, i though it was just my earphone, after i changed it, it still the same, then i upgrade to the QTEK rom, the nosie still comes, the nosie comes as the singer start to sing!!! it makes my so dizzy, i had try to link my BT to my PC, but they sound much different! no nosie plus clearer sound!
the second problem is that when a phone call-in, the ringtone goes via BT rather than built-in speaker???
the third problem is if you set ur BT as both hands free/set and wireless stero, during a connected phone call, if you press any button on the dial pad, all the sound will gone, but the phone is still connected, i found this problem when i using my voice mail?!
also after i update to the non-O2 rom, my phone is no longer accept any MMS, i already config all the setting from O2, is just that i don't have my MMS acount appear on my mail box. i also try the .cab setting file too!
My A2DP BT is i-Tech S35
ROM Version: 1.30.77WWE (QTEK)
Radio Version: 1.09.00 (QTEK)
ExtROM Version: 1.13.188 WWE (O2)
Many Thanks!!!
Was it just me than having this problem???
- I've not the first problem.
- I've the second problem
- I never experienced third problem
:wink:

Click on the above link , download the file and run it on your phone, do not alter any of the options, just click next on everything it will fix your MMS problem
thx a ur advice coff... but it still doesn't work, plus i starting to think that the nosie might cause by my s35, due to the campasility.. (sorry can't spell)
Hi MicmiC901,
Yes, it probably is something "locally" with your phone/headset/area/etc, since I also have same experience as asci, meaning;
1. NO, don't have that problem
2. YES, I have same issue (to me this is actually OK, since when headset is connected, I WANT it to only ring in the headset)
3. NO, never experienced this problem
I use the latest Qtek ROM with AKU2 and A2DP, but have never experienced that high-frequent-noise-issue you mention with any other of the A2DP ROMs on my JasJar (TMobile Germany ROM, a custom-ROM from the forums).
so RonnyGydar, which bt headset u using @ the moment? i just try with my friends logitech bt headphone, it get worse than my i.tech, sound get Stuttering , so i think i better change a new bt, would u recommand moto ht-820?
Hi MicmiC901,
Sorry the veeery slow response...but now I have even one more BT Stereo headset...so then you get the "bonus" of even more info in my reply!
I have 3 BT Stereo Headsets, and here is a short summary of experience of them all.
HP BT Stereo Headphones (same HW as the Logitech ones as I understand).
Sound is good, clear, OK bass. Nothing exceptional, but I was very pleased with them. Sound could be a bit higher at the highest volume...if you plan to use then in noisy environments...but not really an issue...since they are quite loud.
Motorola HS820
Soundwise (clarity and bass) very simmilar to the HP ones...can't point my finger on any differences. But they seem actually a little less loud than the HP ones...so with these I struggeled to hear Podcasts when I sat on a bus going through tunnels. The HP headphones are slightly louder, I think.
Bonus of these are the excellent batterylife and miniUSB plug...plus the HP ones do not have a microphone, so the HP ones are only for music. So I would easily chose the Motorola's before the HP headphones.
One minus for me with the Motorola's are that they hurt my ears after a couple of hours of use. ...that at lack of "powerfull" bass, got me to look at the i-Tech BluePRO's...
i-Tech BluePRO
These have very good bass (and they sure look like they should have it too...pretty big earmufflers...with these, you look like you are working at a construction site or something, but the clarity of the sound is actually worse than HP and Motorola...they sound a bit fuzzy.
...but I still use these all the time...mainly for two reasons. One is the excellent bass (I like to listen to techno and trance...and then bass is important, the other is that they isolate outside sounds (due to the enormous padding), so I can have the sound as low as I prefer...and STILL hear all my music without disturbance from other sounds in the environment (like sitting on the bus in a tunnel, or at a noise Gym).
It also seems that there is quite a bit difference in how the different manufacturers implement BT profiles.
My Motorola and i-Tech BluePRO have problems with "Pause/Resume"-button on headset when used with my JasJar (Pause works, but not resume...or opposite...not sure which it was, dont have the headsets with me today)...but the HP ones does not (I tested them a couple of times, and the HP headphones worked all the time)!?
Re-connection after a time without use seems also to vary a bit. The Motorola I can turn off/on the headset, and they reconnect automatically to my JasJar. The i-Tech BluePRO's I must choose re-connect in "Bluetooth settings" on my JasJar every time I want to use them.
The "famous" "lag-issue" everybody experiences I experience with all my headphones in some situations...and it does not seem any better or worse among the headsets. It seems to also be affected by general radio disturbance, since I have a lot of problems with lag at work, but no problems at all at the Gym (which is good for me...since that is the place I am most happy with having my wireless headphones), and some issues at home.
Hope this was of any help!
actually i have the problem micmic is talking about.. it happened when i upgraded my wiz to a newer rom to get the a2dp function. eventually i do not have a bt.stereo -headset yet.. (coming in about 2 weeks) but i have the issues with the sound. it's almost like a bad bitrate or something? ..wierd it is since i remains even if i downgrade my rom. =/
Hi epluribus and MicmiC901,
Is the "stuttering" you both mentioning the same as I call "occational lag"?
IF it is...it you should certainly not have it when you do the following test;
1. Reset your JasJar/Universal (to clean memmory completely)
2. Started listening to music over headset with...
3. The Universal lying on the desk in front of you completely still 50cm from your face
4. You sitting completely still
5. No WiFi on close to you.
...this test is completely overkill...but if it STILL stutters in that "controlled scenario"...well then it must be something different with your Universal or headset HW. Cause I can walk around with my JasJar (also in areas I know there are 5-6 WiFi connections active...like my appartment), and even put the JasJar on the table and walk 5-10 meters away from it...and have no or at least nothing more than an "occational stutter"/"lag".
It seems to be two major factors affecting this "stuttering"/"lag" (from my experiences at least...I have used A2DP a lot with my Universal...couple of hours every day);
1. Universal struggling outputting(RAM/CPU...or both!?)
One help here is to apply the registry "A2DP priority" fix (found it in the forums here).
Another is to close all programs before using it (I usually do not do this...I usually only do it in hindsight when I get the problem).
2. Signal between Universal and headset struggling (obstructions between Universal and headset, WiFi nearby, so forth)
I for example get this problem if I put my Universal in my trouser pocket (I know, I must have big pockets, and walk around, I get stuttering/lag occationally. If I then take it out, and hold it in my hand farily still when I walk...no stuttering. I have found, that when I walk, it is OK to have it in my backpack/rugsack...then for some reason it very rearly stutters...so I usually do that.
But when I walk of the bus at work, and walk into the "campus" of my workplace, which is cramped with radiotransmitters (is norways largest Telecom company)...I get a lot of stuttering, and need to take it out of backpack, and hold it in my hand, at it gets a lot better.
In short: A2DP with the Universal works, but is sensitive to disturbance/obstructions/moving around...and to make it worse, it is also sometimes dependant of the Universal itself struggling with CPU/RAM.
I have BTW had the exact same problems before with Qtek2020 and Qtek9090 (which I got hold of some "A2DP patches", when I had those devices). ...but I really had a LOT more stuttering with those two...so much so, that I never used A2DP with them on a daily basis.
...so it can seem that HTC is getting slightly better on each new device...?
Hope this info can be of some use!
...but it might not...if my assumption at the beginning here is wrong, and your "stuttering"-issue is something completely different than the "lag"-issue I talk about!?

stereo bt but mono sound

iam currently using latest rom from dopod and motorola 820, although the two earpiece have sounds it is only mono, can someone help to make it stereo? o recomend what rom to use, thanks
In order to have stereo audio on a Bluetooth device, you need a profile called A2DP, which is currently only supported by the latest Qtek Universal ROM at the moment:
ftp://xda:[email protected]_Updates/UNI_QTEK_13077_176_10900_WWE.exe
Dopod has not released a ROM supporting A2DP yet.
thanks for the help, God bless
No problem. Do let us know whether it works well or not.
it works, i have stereo sound, but need improvements, in a song the bluetoth stops 3 to 4 times when playing, the player dont stop its the motorola 820 that stops several times.
I did come across a post with a patch for the A2DP flaw the other day. It's somewhere on this site - do a search and see if you're lucky.
Found it: http://forum.xda-developers.com/viewtopic.php?t=46811&highlight=universal+a2dp
It worked for me for a little while so try it.
Hi,
I have used A2DP a lot with my JasJar the last 4-5 months, and had written a summary of my experiences with this "lag/stuttering"-issue in another thread here...I have copied the most essential of that text below...might be usefull info for you;
-----------------------------------------------------------------------------------

-----------------------------------------------------------------------------------
I also wrote a short post on my experiences with the different stereo headsets I have...yes, they actually act a little bit different it seems (regarding resume/pause button, and how easy/automatic they "reconnect"). You can see it here; http://forum.xda-developers.com/viewtopic.php?t=47977
Hope this is of some help for you!
RonnyGydar: I came across your little summary a little while ago and have done the registry fix, but the problem still exists! Do you think altering the value in some way would help?
richardlai,
I added the registry value manually...found a reg-file (or was it a CAB-file!?) that supposedly should add it...but when I checked later the key was still not added in the registry?
So I added it manually.
BUT, I do still have the problem...but that seems to be radio interference/distance so forth...since when I hold JasJar in my hand and don't move it around, I NEVER have an problem. ...and actually fairly rearly when I have it in my rugsack/backpack.
With 1 or 2 exceptions...where it lagged "all the time"...but then a soft-reset cured it.
So if you have this problem with your phone lying in front of you on the table...then it really sounds like it is the JasJar/Universal that IS the cause (and not interference)...and yes then the registry hack should help.
BUT I have not done any real testing of the effect of it...I am not sure how much effect it really has...all I know is that I had a "lot of problems" with lag before...and now I almost never have it.
...I hate those "diffuse" problems...when it is impossible to measure in a "scientific" way that "this cures it", and "this do not"! :-(
Sorry about the "little help" I give here...but this issue is a bit "fuzzy"...I have gotten it enough under control to that it isn't a problem any more (during a 1 hour workout, I will typically get this gap/lag 0-2 times...and that is not a problem for me...at least compared to what I experienced 6 months ago, where I was lucky if I could hear 10 seconds without any problems).
The stuttering problem seems to be permanent now... Luckily I have a HP hx4700 (which has a Broadcom bluetooth module) and works perfectly with my Jabra HT620s. Anyone using an A2DP ROM other than Qtek? I'd like to try a different ROM to see if it would make a difference.
only a second of sound
i use the qstarz bt stereo headset (http://www.qstarz.com/products/bh-q392s.aspx) and it works fine for phonecalls, but when i set it for wireless stereo and start a media player (TCPMP, WMP, Pocket Player...) i mostly only get sound for one second and then it shuts up. the players keep playing, the buttons on the headset can pause, resume and change tracks but there is no sound at all.
i get full wireless stereo playback occasionally, but i can't figure out what differs from time to time.
i applied the above patch with no success. anyone has a thought on the matter?
Ariel.

I use the BT620s with my Qtek 9000 without much trouble. Here's the trick:
Assuming you have paired with succes. Set headset and BT OFF before starting.
Turn bluetooth ON
wait a second or two
Turn headset ON
wait another two seconds
Now go to BT settings, and connect the headset.
Wait for the little pling sound (the activesync sound ).
Now start Windows Media Player and play an MP3.
Using this sequence has never failed me
edit:
I use the latest OFFICIAL Qtek 9000 WWE ROM. (Without the ExtROM though ) And i did not use any patches regarding A2DP or Bluetooth.
this is what i tried, many times. i get the activesync sound, sometimes from the speakers, sometimes in the headset, but almost always only one second of sound afterwards.
i found that by pairing the headset to the universal by pressing and holding the green button on the headset untill the universal recognises (doesn't take long) gives better results.
pairing it by the instructions of the headset (putting it in discover mode, and then searching for a device with the universal) will give me the one second sound almost every time.

Well, this has ALWAYS been the sequence I use (and I don't think you can do it in any other way). The real problem here is either the buffer memory or processor load.

Then there is no A2DP problem, the only solution is to lower the overal systemload. Stop all programs you have running, disable every today plugin that need frequent updating (memory, battery meters etc.) Free up as much RAM as you possibly can. I have AT LEAST 16 mb RAM free when playing music via BT.

Universal and Jabra BT620s problem

Hi everyone. Not long time ago I bought T-mobile MDA Pro. I guess it's German version since it have QWERTZ keyboard layout.
It has some issues, but it was all software and I fixed it. But I have one problem that I couldn't solve my myself.
I have bluetooth headset Jabra BT620s. Bought it specially for using with my Universal (it's not handy to talk by phone with it in hands). Connected, added as Headset. Everything cool... have to be. But! It plays sound (as headset) this way: 1-2sec playing 30-40 sec silent. I didn't try hands-free because it have no use without listening to music. What had I try:
1. Different ROMS
- WM5 WWE 1.30.77 (if remember number right)
- WM6 J's WWE 2.02.02
- WM6 WWE 2.10.02
ALL ROMs had this issue
2. On every ROM I tried to change "priority" for A2DP (via RegEditor)
One thing helped me. Got broadcomm BT stack application (same was with WM5 ROM, but it seems different version). A2DP worked fine, hands-free too (as you remember I didn't try it without A2DP), BUT(!) all sounds via speakers and headphones (of course, when Jabra was offline) disappeared and my universal becon unresponsive and hanging up often. So I couldn't use it.
Maybe you can help me to solve the problem? Maybe I have to use different BT stack? Or try something with registry? Or... I have no idea.
And, by the way, does anyone knows which broadcom chip is used in Universal? Where can I get all specs (chipset e.t.c.)?
Thanks
Hi,
I had the same problem with my Universal and my Laptop too.
I thought it was a lack of memory problem but trying "light" player nothing changed...
I think that it could be related to pairing problems and the way Jabra BT620s activate BT profiles, because everything got solved restarting Jabra and activating Headset profile before the A2DP.
I solved definitely all the issues with Jabra BT620s using the new firmware with WM6 5.2.1413 and Microsoft Stack (with bitpool set between 30 and 36).
I hope being helpful.
Let me know if you have any interesting tricks...
Hi! Thanks for posting!
I forgot to write that I always trying to activate hands-free firs then headset. And all after powering on Jabra.
Ok. I tried to update firmware of jabra (as topic somwere nearby tells) and connect. Problem persists.
I'm not kinda pro in BT, so tell me what is _bitpool_? And how to set it?
I will google for sometime, of course, but if I won't find that, please, write. Does this mean to mess with registry?

That is in the Registry. I got the info from somewhere (Sorry cannot remember?) But I copied it to a text file, here it is: [HKLM/Software/Microsoft/Bluetooth/A2DP/Settings]
Add new dword, Value name=BitPool; Value data=48 (Decimal)
Modify, Value name=UseJointStereo; Value data=0 (Decimal, Originally 1)
For BitPool:
Microsoft suggests the following bitpool values for optimal buffer sizes.
30 - Low audio quality
40 - Medium audio quality
48 - High audio quality
58 - Excellent audio quality
Choosing 48 is adviced.
For UseJointStereo: use 0 instead of 1 else the streaming is done only in mono mode!
(I have a 8525 so AD2P came with it. I never added any entries I just changed the #'s. )
Gonna try it today, when back from work.
I understand that reducing quality gives better stability and performance. But I want true stereo, not joint.
Ideally I want get same sound as I'd have in wired headphones.
I have the same problem with this headset, after 6 hours testing, severals flashings with the best wm5&wm6 roms, i cant make it work!
Please help, i had changed the bitpool from 30 to 60, one up at a time (30,31,32...60) nothing happens.
I heard half sec music and then silence. WTF???
try to use widcomm stack. but the quality of music in mine headset using this stack is not very good. and there are some bugs such as no sound after disconnecting the jabra. if you find some solution, please post it here!
widcomm stack works great, finally after 6+ hours i heard sound from my headset! The sound is pretty good, also when i turn off the headset, the sound playback from the device.
f#ck you M$ with the crapy bt stack, i have lost half day.
Thank you l2tp.
Solved!
It was a bitpool. Little gude:
It was my WM6, so no keys were added.
Use registry editor
[HKLM/Software/Microsoft/Bluetooth/A2DP/Settings]
Value name=BitPool; Value data=48 (Decimal, Originally 30)
Value name=UseJointStereo; Value data=0 (Decimal, Originally 1)
Value name=MaxSupportedBitPool; Value data=500 (Decimail, Originally 30)
As I figured out, MaxSupp is some kind of "cache". When I tried 100, it became laggy after 30-40 minutes. But with 500 2hours played perfectly.
But! Have to solve 2 more problems:
1. Bad connection.
I'm carrying my Uni in bag and when comething getting in the way between bag and my head (i.e. my hand when I taking something form the bag) sound dissapears for 1-2-3 sec. It's not nice.
Maybe I should try widcomm stack? The question is where I can get it and what the type it should be? (don't post please "on widcomm site", give me as widcomm.com, I just can't search for now)
2. It's too quiet.
Wired headphones were pretty louder. Since I using subway 1.5 hours per day you can imagine that without 100% volume I can't hear the music normally.
I put Jabra on 100% and Uni 100% volume. But it like 50% of wired headphones' volume.
Should this be normal (Jabra less quiet), or can I do something?
YES! I know how it works, that Jabra have internal amplifier and BT signal decoder, but...
Of course, I don't wans to dissassemble Jabra and making hard additions to it (unless it will be a kind of volume regulator).
I need that Jabra played for nearly 5 hours. So I can spend attioional power of Jabra (in manual said that It can play for 14 hours, so I can get 195% boost in power).
Thanks everyone participated in this tread.
Argh! The M$ stack gives me creeps. Very unstable. It seems, that my Uni have not BT but some kinda radio transmitter back from WWII! Loosing signal in distance less than meter! I alwayes hated, will hate always M$ corp. OpenSource rules the world!

I cant understand why the p3300 works fine with jabra bt620s, and it has wm5.
I am still use broadcomm stack, not only works fine with bt620s, but also better with my gps receiver.

Ahem... On WM5 and shipped BT Broadcomm stack it still has bad connection!

8525 with wm6, bluetooth suddenly bad

Hay guys. I updated my 8525 to WM6 around Thanksgiving, and everything was great. I had no problems at all. I decided to whip out my old i-phono stereo bluetooth headset and try it out with the superior A2DP quality on WM6. It worked really well, though I decided to go ahead and remove the BitPool and MaxSupportedBitPool registry keys as well as most people suggest for increased quality. It worked really well up until yesterday when I tried using my headset, and everything went wrong. When the headset syncs with the phone, the phone starts facing a lot of slow down. The worst thing is that when I try to play music, the music stutters hella bad, and the quality is very low. It's almost like the phone is super busy type of poor playback, which can happen even without using bluetooth, though the problem is exacerbated when trying to stream music data to the headset.
Short of a hard reset, I haven't a clue what to do, or why it is doing it all of a sudden. I've already tried the task manager fix, and related .cab fix, but it did nothing for me. Really ticks me off....
WTF guys!?!
Same Problem Here I Think
I upgraded my 8525 to WM6, reinstalled all my aftermarket ware and suddenly the stream to my Motorola S9s is all static filled and has a very low volume. Everything else works great. Even the 4Gb SDHC card...
I've been all over the net looking for others with this problem and you're the first I've found.
I'm actively looking for a fix and will reply to this thread if I find one.
Hi Guys,
I have a simular probelm, I am Using Schaps WinMob6 3.56c Multi with a Motorola S9 BT Headset, on an HTC Hermes. The Volume iss ok, sound quality decent, what's driving me crazy ist:
As soon as I start playback everything slows down so bad that it is almost impossible to use the phone. Opening Opera takes about 60sec. Menus lag badly. I have tried playing with the settings nothing helps.
Setup:
Use Joint Stereo: Yes
Sample Rate 48000 (for some reason i can not change this)
Bit Pool: 86 (default)
Max Bit: 86 (default)
Changing the Bitpool seems to make no difference
To summ it up
Help would be appreciated!
If I find something that helps I will post it here ASAP,
Have a good one,
Chris
