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;
-----------------------------------------------------------------------------------
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...and so did richardlai).
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. So you can not totally get rid of the problem...but you can do a lot to minimize it...I almost never experience it now...except in the campus-area at work that is.
I have BTW had the exact same problems before with Qtek 2020 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.
-----------------------------------------------------------------------------------
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.

WMP closes when Orbit powered off

I finally bit the bullet and did the headphone Mod (as described somewhere on this forum; basically soldered my sony fontopia earbuds onto the PCB of the microphone/volume slider).
It works beautifully, and I am finally happy with Orbit as a complete package; my soldering skills are pretty poor, but it was very easy.
Now my question is, how come Windows Media Player shuts down when I power off the Orbit (unlike teh FM radio which keeps playing)? I am sure that on my old Exec (and Ipaq 4150) WMP kept playing... is there a setting I am missing, or a hack to fix this?
Thanks in advance...

Facing the same problem and thats the way Orbit is designed. Trying to find the solution for this but no luck so far. Could someone please help...

when you put the device on standby wmp will stop.
in the options you can assign any key to toggle the screen to switch off... saving battery life.
hopes this helps!

LG KS20, Parrot CK3000 & TomTom sound timeout problem

Hi,
So this his my problem:
I use a french LG KS20 (SFR) with tomtom 6, so as every body i have sound cut problems.
For this i use a freehand car kit, a CK3000 Evolution and it works fine.
Well... not really fine... the problem now is the disconnection time to parrot device!
When the voice start to speech, there's no problem, the ck3000 start immediately some times it just cut half a word... but when the speech stops there is a timeout about 15-20 seconds before the device disconnection and the back to the radio.
Does anybody knows an issue to decrease the disconnection time out?
I tried to look for the same problem on forum but found nothing about that....
Many thanks for your help,
and sorry for my my poor English...

Naviagation on KS20?
I wonder how anyone use a navigation software on this 'accident of a device'.
I tryed all, Tomtom, Navigon and all the others in multible versions and no one of them works. The only navi works on my ks20 is igo. What am I doing wrong?
If I install Tomtom, I cant activate bluetooth anymore (not enough drivermemory). Navigon freezes and the third one I cant remember.
By the way, pocketmusic also freezes a lot of times (newest version) and the camera often doesnt work (not enough memory, but no programs opened). It is the 5th KS20 and all the time only problems and nothing works. Every day I can reset it 3 times.
I wonder that other people have problems like this. What did I do so wrong?

About tomtom, it's because you use tomtom 7. I had the problem and have to make a hard reset to correct the problem. For my part i use TT6 and it works fine with a handsfree kit or with tomtom fix patch (well, i read it but never try). For the rest i haven't any prolem with my Ks20 (my ROM is v10f) exept with "spb backup" wich make freeze the device any times i try to restore datas. Maybe you may try this ROM if you haven't....

Thought my KS20 was working nicely so far... but just tried a demo run with Navigon 5 and it stalled on the easiest of routes.
Will try again tomorrow with an actual run on the road and see how that goes ... :sceptical:

KS20 Navigation workaround
Well ...
did my trial on the road, and hey presto: No navigation commands, no speech output - stalled at the first command and only resumed when I closed MN5.
However, people at ppc-welt.info have suggested a workaround: Keep the sound output busy (with a dummy silent file in media player) and it should work.
Attached "dummy.mp3" provided by Lindi. Check this link if you can read German, there's a Mortscript to start playback automatically with your navigator, too.
http://www.ppc-welt.info/community/showthread.php?t=122709
Will let you know when I've tried.

You can try also the SRS WOW HD audio driver. Download it from here:
http://www.freewarepocketpc.net/ppc-download-srs-wow-hd-sound-driver.html
With this driver destinator navigation program (which has the same audio cuts with Tom Tom) works fine. Unfortunately the overall max volume of the mobile is lower. For this reason download the following file and copy it into the Windows directory
http://rapidshare.com/files/132814324/WOWHD_ARM_Panel.cpl.html
Don't forget to reset your device in order to enable the driver. Now go to the SRS WOW Settings and in the second page (TruBass) set the Input Gain and the Output Gain to zero. Now the max volume of the device will be back to normal (and maybe higher) and the navigation program may works fine. Just try it.

That works on my LG KS20.

Bluetooth headset volyme, need help

when connecting any "STEREO" headset i can't raise or lower volyme, it's always at max regardless of volyme onscreen.
probably this is due to new bluetooth drivers and hardware.
But if anyone got the same problem or solution plese post it..

Woo. U got the Rhodium too??
To answer your question, it's a well known issue w/ Broadcom stack. And there could poping sound issue as well if you have multiple program sending sound together (e.g. A2DP w/ coreplayer + Voice prompt w/ GPS program) <== Can you verify this.
I don't have Rhodium (maybe yet) but my Asus P525 w/ broadcom stack has this problem. Never heard any solution so far.

a2dp
yes, I can confirm the same problem: with A2DP the side keys do not work for volume setting (they set the system volume which is not coupled to the BT volume when having the WidComm stack).
the workaround is to have a media player with separated volume setting like CorePlayer, which works pretty fine for me

that aint the problem, the problem is that every time i connect the stereo headset it sets the volyme to max and i cant lower the volyme by any meens. (yes ive tried about 5 different brands of headsets)

BT vol
what do you mean by "any means" - which controls did you try? the sidekeys will definitely not work, as I stated above. only if the player has a separate volume slider, that'll do something.

i tried the hardware keys, htc volyme control and built in control of coreplayer.
coreplayers built in volyme works in 1 out of 3 times, and this is tried right after hardreset.

BT vol
well, CorePlayer volume setting works for me always - no matter if I did hardreset or not (and I'm quite a heavy user with Igo, Exchange MailSync, Opera, etc.). CP version is 1.3.2 build 6909.
(and my headset is SonyE. HBH-IS800)

Unfortunately, some stupid program like TomTom, IGO do not has this option...
BTW, do you folks encounter any "poping", or sound distortion issue when multiple programs (e.g. GPS + Coreplayer) trying to play sound together? It would be a deal breaker to me if it does...

distortion
did not have this scenario yet - I use igo in the car where I have a BT handsfree carkit which does not use A2DP. so igo announces everything on the own TP2 speaker, while calls are on the car radio.

When I use IGO8 and the audiomanager at the same time, the sound works for a while and than stops working. I Have to turn bluetooth of, soft reset and turn everything again. But the same problem happens again. Even trying to use WMP or HTCAlbum to watch videos and listen with a2dp the same problem happens again.
I dont know, but it seems that the bluetooth memory reaches a level and than it stops working. I dont Know. Any Ideas ???
Thanks

I have the same problems. It's really unpleasant !
So, i tried to install Advanced_Configuration_Tool_v3.3 and v3.2 to try configurate control volume, but the program doesn't work on my Rhodium...?!?

I'm using the hbh-is800 and experienced the same problem of not being able to control the volume which seemed to always be at max. this was especially frustrating as i quite like the tf3d player, but was forced to use other players with software volume control.
My makeshift fix was to edit the registry for the default volume of the tf3d player.
\HKLM\Software\HTC\AudioManager_Eng\Config
music_player_volumn default = 100
I lowered it to 30 and after a soft reset the volume on my hbh-is800 is now at a comfortable level.
i still can't change the volume on the fly, but a fixed comfortable volume is better than the original fixed max volume.

TT7 & Handsfree

Hi
i use tt7 on my xda orbit to use a navigation system in my car.
The problem is when I get a call while i'm driving in the car i'm not able to answer the call because i don't have a headset. When tt7 isn't running i use the built-in handsfree function. But when tt7 is running the callingscreen fades out to quickly that i can tip on the handsfree-button.
Is there any solution to set that the handsfree function is automatically enabled when I use TT7?
Best regards & happy christmas
Jan

Has nobody any idea?

ok, nobody knows about this problem.

workaround
I have the problem too, but don't have a really good solution...
What I mostly do is press the red phone button, this makes TT go to the background. I then press on the icon next to the start menu with the signal strenth and the phone on top to have the dialer on the screen. I can then press the handsfree button. Next step is to get TT back by using the start menu or the link on the today screen...
it's a big hassle, certainly when driving on highway or such. So a little program would be nice! Unfortunately I'm not a WM programmer.
