Ok, we have some smart people here at XDA-Developers so why has no one been able to come up with a hack for the low volume on many of these units? The SX-56 has really good volume in both the earpiece and the speakerphone but it seems all other HTC units do not!
When using the media player the volume on the speaker is adequate (not great); however the same speaker as a speakerphone can barely be heard unless one is in a quiet room. The earpiece volume is terrible in a noisy environment. If you compare this to almost any tiny phone it sucks to put it bluntly. Take my LG 4500, it is so loud that you have to turn it down (this is as it should be).
From what I have seen, changes in the ROM can effect the volume so this tells me that there has to be some value stored away in a .dll that limits the max volume. I have searched for a registry value but none seems to solve the problem. The same hardware used for Media player has to be used for everything else, i.e. amplifier and speaker for spearkerphone and just switched to earpiece when in normal phone mode. Thus the amplifier is capable.
Can someone identify the .dll used for audio? Is it different for the various models? Does one work better than another? Is there a hacked version that would work better than all of the others? Is it in the volume control .dll?
Anyone that can solve this problem will be a hero in my eyes and a true hacker in the best sense of the word. I have the new HP IPAQ HW6510 (also made by HTC) and it has some improvements in the version of Windows it has, such as the Bluetooth stack really seems to work well; however, since the unit supports Bluetooth 1.2 I'm not sure whether it would work with version 1.1 phones.
Thank you for any help you can provide. I searched the site first and found many other complaining but no solutions.
Doesn't anyone have a clue? Is there anyone that can explain the workings and which .dlls do what relative to audio? Surely there is some bright person that has been able to figure this out.
pda2k user here. NEVER had volume problems. lucky?
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

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!?
I have asked this question in several other threads and have not recieved a response. I have also searched all threads within 1 week history for A2DP content and cant find my question answered anywhere... so here goes!!
Can people confirm their experiences with A2DP on the official Wm6 roms.
Does the skipping still occur with default rom settings?
Do you still have to install sleuths a2dp patch to get things anywhere near stable?
Is default sound quality good?
Is tweaking the bitpool and other reg settings still needed?
I have battled with all other roms and my Motorola Ht820 headset to get skip free good quality audio and never managed to get it working consitently and was waiting for the official WM6 roms to see if they would crack the issue?
All feedback appreciated.

I've had no problems with A2DP in the official Dopod WM6. it works great straight after install with no tweaks at all. It seems to be skip free and with good sound quality.
The only problem I still have (and had with every version & tweak) is playing m4a files with WMP. When playing these files, the phone goes back to the speaker...

Cool thanks for letting me know, is it working in official rom for anyone else without messing about with fixes?
Come on guys some of you must be using A2DP?

Big A2DP User Here
I'm a big A2DP headset user when working out, so I have been keeping a close eye on the sound quality with the different WM6 ROM versions here. As posted before, the version from Sleuth was GREAT in sound quality.
The "official" WM6 ROM from HTC for Cingular/AT&T (US) does have the registry entry for UseJointStereo set to 1, so that is great. However, I did see that the MatBitRate and SampleRate were also there and set to 30. So, following the "best" settings on this forum, I deleted these two registry entries and added the increased rate entry of SampleRate at 48000.
The workout this morning sounded as sweet as with Sleuth's ROM.

Sounds promising, just gonna try my headset now with official dopod rom. Fingers crossed. What head set are you using?
I have a parrot hands free car kit and I find the quality is best when I just leave all settings as is. I think the a2dp on this rom sounds exceptionally weel.
I'm using the Motorola S9 headset.
I still have the skipping issue with Dopod SEA version and SE HBH-DS970. Before that I had one of LSVW's ROMs installed and AD2P used to work just fine in that rom.
yup, the dopod release does not seem to have all the fixes done here. i have tried LSVW and black and no more skipping issue with my DS970.

Apply Sleuth's patch...
Did you apply Sleuth's patch? I wasn't sure if it would work on WM6 (official), but, thank goodness, it does! After 9 months I can listen to music!

Hi, Was hoping that the patch that sleuth did (to fix the looping code error) would have been incorporated by M$ into the release. Looks as if it has not, which is a real shame. Just about to flash Black Satin and will try with and without Sleuths patch and post the results. Thanks for all the feedback guys, much appreciated.
on a whim i knew what a2dp was but i just wanted to wiki it..
check out the LAST LINE...
Advanced Audio Distribution Profile (A2DP)
This profile defines how high quality audio (stereo or mono) can be streamed from one device to another over a Bluetooth connection[1] - for example, music streamed from a mobile phone to a wireless headset.
A2DP was initially used in conjunction with an intermediate Bluetooth transceiver that connects to a standard output audio jack, encodes the incoming audio to a Bluetooth-friendly format, and sends the signal wirelessly to Bluetooth headphones that decode and play the audio. However, many Bluetooth 1.1, 1.2, and 2.0 mobile phones and portable media players natively support A2DP, and most newer Bluetooth 2.0 headphones support it as well.[2] Bluetooth headphones, especially the more advanced models, often come with a microphone and support for the Audio/Video Remote Control (AVRCP), Headset (HSP) and Hands-Free (HFP) profiles.
A2DP[3] is designed to transfer a 2-channel stereo audio stream, like music from an MP3 player, to a headset or car radio. This profile relies on AVDTP and GAVDP. It includes mandatory support for low complexity Sub Band Codec (SBC) and supports optionally: MPEG-1,2 Audio, MPEG-2,4 AAC and ATRAC, and is extensible to support manufacturer-defined codecs. Most bluetooth stacks implement the SCMS-T copyright protection. In these cases it is not possible to connect the A2DP headphones for high quality audio. E.g. the Motorola HT820 can be used for high quality audio only with certain versions of the Toshiba bluetooth stack.
HOPE THIS HELPS!!!!
Offical SEA WM6 ROM fixed all my A2DP issues with my BlueAnt X5 headsets. (No tweaks at all required)
One problem remainds... it pauses/skips if Wifi is left enabled. Not sure if that is a software or a hardware issue (both protocols use the same frequency)

Hi, thanks for the article, but dont think this is the problem as I am now getting a lot better A2DP support, no problem with playing the audio or the quality just the skipping. Nothing really has changed, it is a bit more stable but needs sleuths A2DP patch to make it usable. My point is that is sleuth could fix this with a bit of code at home (no offence sleuth) then could M4 not have used the might of their developmental skillset to fix this most annoying problem.

1. Yes, I still got skipping after installing vp3G's v3.61 ROM.
2. So, yes, I installed Sleuth's A2DP patch.
3. That is all I did, and the sound is pretty good on my Motorola S805.
4. I haven't dome any registry tweaks, though I may to see if it makes any difference in sound quality.
Bluetooth stereo headset: Sony DR-BT10CX
Problem: The playback pitch is changed after silence
The solutions form their support site http://www.sony.co.th/support/faq/189664/product/dr-bt10cx/modelfirst?site=hp_en_TH_i:
(1) Check interference with Wireless Lan or other Bluethooh connections.
(2) The communication condition may improve by sliding MODE switch to MODE 2
My question: what is MODE 2? How to switch to it? MODE 2=discoverable? MODE 1=connectable? Can someone answer, please?
Thanks in advance.

HTC artemis, Moto HT820 headphones, touch 4.01 rom. on resume, it sounds *fractionally* faster for a second. I though I was imagining it...!
Update: The silence and pitch change is caused by interference with other wireless connections. In this case that is WiFi ~ wireless LAN. At the university some points are sensitive. Now, there is very little to no interference anymore. Speculative, the battery status may also play a role here.
Next to this, switching to MODE 2 (where the reception stability takes priority) might be a hardware switch on the Bluetooth headset, according to the manual of some other similar products. I haven't found such switch on my Sony.
I have it too
I have noticed the same on my EXIBEL BT stereo headset when listening to music from my TYTN II. It lasts for periods of several seconds, and is quite annoying. BTW, this happens even when i'm out walking in the open, presumably at a fair distance from any WIFI transmitters.
Yes, I have the same problem with my HTC One S (villec2) and cheapo sports headset. I can't really talk about the state of the art, since this phone is stuck on Android 4.1.1 -- but it just beggars belief that any developer anywhere thought it was acceptable to deal with buffer under/over-runs by varying the sample rate, and hence the pitch and tempo, during stereo playback. Do these people never listen to music?
What probably happened was that the Bluetooth audio system was originally designed for hands-free telephony, where low latency is paramount and pitch changes are barely noticeable since the content is just speech. This system was then re-used for stereo, when what they should have done was allow a larger buffer and longer latency (which doesn't matter with music playback) to cope with data interruptions. Lazy engineers.
Anyway, turning off Wi-fi greatly reduces the incidence of pitch shifts, but does not eliminate it completely. I look forward to the day when there is a supported custom ROM for my device based on Andriod >= 4.2, which apparently has improvements to Bluetooth data delivery. Bt I'm not holding my breath.
Bluetooth issue
I have the same problem with the Bluetooth skipping as well. I heard that it may be a interference problem with WiFi but its most likely the ROM. This ROM has stopped me from constantly switching to other roms because it has all the features I want and the battery life is great. I just hope that the Bluetooth issue can be fixed in time. :good: :good: for this amazing ROM though.
My opinion is that the bluetooth audio quality on the HTC Desire is terrible!
When playing music, in most of the tracks I hear clicking/crackling noise when some frequency/dB/something else is reached.
To illustrate what I mean, I have uploaded an audio fragment in which you can hear a similar noise.
Download fragment (MP3) Warning! it's drum n bass
You can hear the sound at the very beginning and at around 6 seconds (and at the end). As if a tweeter (speaker for higher frequencies) get overloaded.
I don't know if it is related to the phone's hardware, (radio) firmware or the Android OS. I've tried different music players, radio firmwares and custom roms. I also enabled an equalizer for bt audio using DSPManager. Unfortunately, nothing helped
edit: Using current versions of DeFoST or OpenDesire (and maybe others), the bt sound quality is how it should be! Fixed for me, but I hope an update from HTC will do the same.
Btw, this crackling/clicking is not only related to the HTC Desire, I have heard it on more (non-android) phones that were connected to my bt audio setup (in car). Unfortunately I haven't been able to test other Android phones, but my old Nokia N82 and SE K800i always sounded clear.
My guess is that it's just a non-controllable system setting of Android to solve the problem, but I don't know where (config/settings files?) to search for BT audio settings.
Any ideas?
That's the typical audio quality of a mediocre A2DP device: give a try at a Sony Ericsson MW-600 headset, you'll see what an Hi-Fi Bluetooth device is.

I'm running Defrost rom now and the sound quality is perfect, how it should be! So, it's not related to the audio device, or the default settings/drivers of the Desire are "too good" for my audio device (Pioneer BT unit @ car audio), which I think is not the case, since I also had this noise on my Logitech Pure-Fi.

Actually I recently owned this headsert but the quality of the sound was still terrible. I thought it was a problem with the headset at first, but that is not the case. I returned it and bought a Jabra BT3030 and the problem still persists. Anyone know if this is actually a problem with the phone or is it software related? I can add that I don't hear these noises when streaming audio through e.g. the youtube app, only mp3 and it doesn't matter which player I use (I've tried loads).
I have the jabra dogtags, audio playback sounds exactly the same as when my headphones are plugged in direct (tested it several times, culd not tell the difference), except that I have a louder volume via the jabra, which is all good as I listen to drum and bass also. Mabey device fault?
It is software related. Using current DeFroST or OpenDesire roms (and maybe others), bluetooth audio is great

well if it would've been device fault you'd think that I'd hear that noise through youtube streams as well.
But yeah as tutti-frutti stated it might be a software issue, which points me towards a root. But since I'd rather not root atm, anyone knows any other solution?
Might try a hard reset first and hope for the best. I will get back to you on that .
Thank you so much for describing my problem!!
I am currently downloading OpenDesire. Just in case that it does not work, where do i find DeFost??? I can't find it on the Market.
Thanks again!
I have Samsung Epic 4g.
nope Desire's Bluetooth audio quality is good in fact Awesome..!!
-May be the problem is not with the phone, its with Bluetooth head set you are using.
-My suggestion is to use Nokia or Motorola A2DP Stereo head phones
-I'm using Motorola motorkr S9 hd ,,,its awesome..!!
-Try this ,,it might work

For me, it is an issue with my car, not headphones.
A little UP!
Having the same issues with a Nokia BH-504 headset. Music quality is poor with every Sense ROM (original, rooted, Sense HD, whatever), sound like the tweeters are overloaded.
Definetly not a problem with the headset, it sound perfect with HTC Legend.
Tried to switch to non-Sense ROM (DeFrost, OpenDesire, etc.). The quality is perfect, but music play stops every 1-2 minutes for a second. Very irritating. Anyone experienced this? Is this a problem with my Desire, should I send it for warranty? (Don't want to send without enough evidence, don't wanna be without a phone for weeks...)
Okay, update: Tested the new Gingerbread AOSP and still having these stops at 2-3 minutes. Very strange...
Anyone any idea? Can I debug the bluetooth transfer somehow? Logcat didn't really show anything... Can it be a fault of the phone?

You need an sd r/w-buffer fix in kernel to stop that. I don't know if it comes with any senseless rom though. Maybe you could try the lite version of baadnewz hd rom.

Thanks, I'll look into it. But if that's the problem, it would affect music playback with wired headphones too, isn't it?
And with Sense ROMs I have the overloaded tweeter-like problem, but no stutters. With non-Sense ROMs I have beautiful audio quality but music stops for a second randomly.
Update: Checked Aura ROM with sdfix, no problem with stuttering, but still the overloaded high-frequency problem. Meanwhile I checked that this SD fix is available only for Sense ROMs because it's HTC's hacking, the AOSP versions have no SD problems.
Oh, good lord! I was nearly to believe that I'm some sort of audiophile!
I'm using Plantronics 903 with my Desire and sound quality is just OK (I'm using SENSE ROM, will try OpenDesire in a bit). However, I cannot say I was expecting more.
What funny is happened today: I paired my 903 with PC today - sound quality was nearly same like my Desire, then I noticed someting in Bluetooth Setting Panel of PC. There was a combo box which labeled as "Audio Quality" and it was at the "Low" setting. I switched it "High Quality" and reconnected the device and voila! The sound has been thousands of times better!
Now I'm wondering if such a switch is also available in Desire? Maybe not obvious, but a Kernel variable perhaps? Damn that I don't know a sh** about programming these devices :'(
EDIT : Funny - I think that setting was not of PC's, but Headset's! It's quite well right now! And I didn't even try OpenDesire yet!

A little UP!
Having the same issues with a Nokia BH-504 headset. Music quality is poor with every Sense ROM (original, rooted, Sense HD, whatever), sound like the tweeters are overloaded.
Definetly not a problem with the headset, it sound perfect with HTC Legend.
Tried to switch to non-Sense ROM (DeFrost, OpenDesire, etc.). The quality is perfect, but music play stops every 1-2 minutes for a second. Very irritating. Anyone experienced this? Is this a problem with my Desire, should I send it for warranty? (Don't want to send without enough evidence, don't wanna be without a phone for weeks...)

I have similar sound issues on non-sense roms. I believe it's mostly to do with range is just not quite as good as with sense based roms. I haven't had time to really figure out why yet.
Okay, so they replaced my Nokia BH-504 headset with a new one, still the same issue with Desire Sense ROMs but Legend Sense is still good. So it's not an issue with the headset (well, could be a general incompatibility problem, but I don't think so) Will check my laptop and a Gingerbread ROM on the Desire. Okay, conclusion after further tests with the replaced headset:
with Desire Sense ROMs: horrible quality in the high frequencies with every MP3.
with Desire non-Sense ROMs (OpenDesire, Gingerbred, etc): Good quality, but music play stops for a secons every 1-2 minutes.
with HP TouchSmart TM2 notebook: Quality problem AND music sutter BOTH
with HTC Legend original Froyo ROM: No problem
with Sony Ericsson X8: No problem
with HTC Touch HD: Quality problem
The headset has been replaced with a new one, same errors occur.
I have no idea what's wrong. I can't believe 2 phone's and a notebook's Bluetooth chip is faulty. So this could be an incompatiblity, hooray for great Bluetooth standard specification I should try a Nokia BH-905 and a Sennheiser MM400, will try them after buy (in the store!) and hand them immediately back if there will be a problem with them
Chapell, I have the same problem as you, with the Nokia BH-504 headset. So far the headset works great with the stock ROM, LeeDroid ROMs or just about any Froyo ROM. Gingerbread-based ROMs or Cyanogen nightlies, or any of the AdamG's Oxygen ROMS, on the other hand, they all have the same issue - every 90 seconds or so there is a glitch, the audio stream skips for half a second or so - very, very annoying keeps you from getting in the mood.
My observations: it is not SD card related, youtube video with the audio part streamd through the bluetooth headset also skips (also tried an SD read-ahead zip patch - no change); also, the glitch doesn't manifest using wired headphones; it has nothing to do with CPU spikes (the music player and the BT connection were the only open applications after a fresh ROM install); it has nothing to do with WiFi being on or off; it has nothing to do with 3G/2G network being active or not, or the GPS; using a different radio also doesn't help (scenario - radio X used with N.S.A. ROM -> no glitch; the same radio used with Oxygen 2.0 RC7 -> glitch)...
My guess - as noobish as it may be - is that this issue is related to some kind of buffering in the streaming process - I compared a few bluetooth configuration files in various ROMs, but couldn't figure any setting related to buffering or such.
If anyone could help, I would be very grateful!
Thanks for the info. If I understand correctly, you had no problems with BH-504 using Sense ROMs. So no high frequency distortion, nothing. This means that my phone is definetly faulty
However it seems the non-Sense skips are not unique for me. Strange, no one uses a BT headset with non-Sense ROMs or it could be a problem only with the BH-504?
