I found this tip on another forum.
Try installing this taskmanager, start wmp and then the task manager, close any apps you don't need to use and then set it to monitor system load.
http://www.iaccarino.de/silvio/ppcstuff.htm
No more skipping on my HBH-DS970! Perhaps it works for other stereo headsets to?
I'm listening now with the "Excellent" setting in Hermes Tweaker. Before launching this taskmanager as per above music would skip at least every 20 seconds - not now, no skipping and quite nice audioquality, it's so sweet!
I hope that there might be some clue for you tweaking gurus how to perhaps implement something perhaps in the Hermes Tweaker that does the same thing as running this Taskmanager.
why no body respond to this thread since the whole forum is talking about solving bt stereo skipping problem? And this guy here said this problem is solved. Because nobody believe this is true? i can confirmed this is real. This method really solved the bt skipping problem. so what the hell you all waiting.
Faster download it and update the wiki!!! thanks
You can also use Magic Button...
I've never had a problem with A2DP skipping.

I must say I'm very suprised to at the low interest! Where are the gurus that can figure this out and perhaps use it in the Hermes Tweaker or as a way of finding out how to improve things even further.

I'm sorry but you have misunderstod this thing. I don't need a taskswitcher, but by using it as I mentioned above the probelm with skipping audio that most people experience with stereo bluetooth headsets are gone.
If you never had a problem with stereo audio skipping, what headset are you using? Have you used the Hermes Tweaker to improve the A2DP audio quality? Set it to Excellent and I think you will hear some skipping if you don't run the program mentioned.

Nice to hear it works for you to, great audio! What BT headset are you using?
As a workaround, its a bit kludgy.... What I am doing is researching the reasons why it works as an insight into the root cause. Perhaps that taskmanager's developer could enlighten us as to what he's actually doing to "monitor system load". I might fire him off a message on this ITNF.... If it doesn't slow down the TyTN drastically, I could develop a service that just does this in the background.
At any rate, I'll be loading up the fix today to play around....

Great to hear!!
Tried it, installed the Task Manager, set the BT audio quality to Excellent with the fit4cat Hermes Tweak tool and I still get skipping.
Is there any difference between using Windows Media or PocketMusic to play audio?
I have the Jabra BT620s headset.
Well, this solution does help the skip but does not eliminate it on my iPAQ headset. The problem sounds more like a scratch on a record now than a full breakup and as such is more bearable. Perhaps theres a way to tune this further with A2DP registry settings. I'm running a bitpool of 58 with maxbitpool set to 80 currently.
Damn.... As I was writing this, the skipping just stopped! WTF ????
Maybe A2DP just chose a different bitpool value. Everything's running perfectly now!
edit: the skipping returns when I quit the taskmanager and stops again when I run it so the taskmanager is definitely involved here.

I don't know what bitpool the Hermes Tweaker sets, but setting it to good prouces a lot of hissing sound, going to "Excellent" it sounds very good on the HBH-DS970.
@Moskus: plz elaborate on how you're using magic button to correct the skipping problem? Also, what BT stereo headset are you using?

Did you also run the Task manager and set it to monitor system load, so you see the graph on the screen?
Yes I did.
I tried plying audio with Windows Media and PocketMusic, both have the same problem. Music plays and at random intervals it drops out (silence, but audio plays) after a few seconds audio resumes.
edit:It does however look like it is skipping less when I use the Task Manager.
What you stop ?
I installed also and i have same skip problem ...
Tell me one think ... after a soft reset, what programs you stop on task manager ?
I stop all prorams but i have a lot in the process tab also.
Can you post your reg values and where in reg must put that values please ?
Thanks
I tried it and I can get no skipping with bitpool set at 48. i cant go higher. This is better than before. But I have another issue. I just upgraded to the 1.35 rom, but b4 i had the cingular. Over the tytn is zippier with the new rom, but in both cases a2dp dies (even with the new kludge) if my maxsupportedbitpool is greater than 30. I presume this limits the bitpool at 30 anyway.
Also it may be me but it seems when i first start p the taskmaster it shows CPU running about 15-20% higher than after a few seconds of running it. Does it somehow kick in some other mode? Finally I guess this makes sense but the CPU works harder with higher rate encoded mp3 files (with 320kbps files it was running at 70-80%, with 192kps files at 50-55%). Does this make sense (I never thought about it b4).
Finally with bitpool set at 30, i can listen to internet radio (virgin UK!!!) over wifi and use bt headphones with no skipping, as long as task manager is running. Could not do that b4. But sound is less than perfect.
No Doubt, it is good discovery, I had Wiki stereo BT headset, It is working perfectly while set Medium, high or excellent in A2DP profile (Fit4Cat) alongwith Task Manager running in background (Minimize), But if I do not start task manager in parallel, The default skipping problem come back.
Basically, My skipping was ok since I bought Nokia HS12w, But Now I am in position to use Wiki stereo HS, as Wiki had long battery life then Nokia. Of course LCD & some other are plus in Nokia HS12W, But LCD does not have major role as Caller ID BT stakes are not working yet. Therefore WiKi is still good Choice if used for stereo MP3.
Thanks . Jompao . to make my stereo BT HS alive. BTW It is observed unmatched stereo Quality if set to excellent (no distortion)

I didn't kill any processes, just shut down tasks Iike active synk or so. I have noticed when playing through speakers CPU load is like 17%, as soon as I turn on bluetooth and headset connects it goes to 100% a second or two then stabilises around 70-80% so you don't want a ton of extra tasks running at the same time.

Did you try to lower the quality setting with Hermes Tweaker or even turn off the A2DP tweak?
The quality of music with A2DP is really bad, have much better sound with my qtek s110 with a2dp hack. I have been using the same sony ericsson ds970. Is there anything that can be done about it?
perhaps you can follow the instruction to turn on the stereo, then the sound will be better.
This is my experience to. I had a SE m600i before and the sound was way much better on that device.
The sound clearly suckes with the headset that is packet with the P3600.
The sound on the S100 was far more better.
Lets just hope the ATi chip get's activated on the rom-update, so that the Graphics and Sound get better.
guys, could you please be more specific? what exactly made you unhappy about the sound produced by HTC Trinity?
please define the problem. is it too soft, too loud, lacking bass or higher frequencies, choppy, etc, etc????
P.S. forget about stock standard wired headset supplied with your Trinity. it's bad.

Guys try using the Hermes Registry Tweaker
I used the hermes registry tweaker to take BT Stereo sound from "Okay" to "Excellent" the tool has five levels of quality as well a tweak to enable true stereo rather than joint stereo.
It worked for me! You can unlock and mount EXTrom too.
http://www.theunwired.net/?itemid=3311
It has a desturbing sound on the higher tones and the bas is muffled. I tried the fit4 program and changed to the best quality, it sounded a little bit better but it was hard to hear, beacuse now the music skips even more thnat earlier. You know you ger music for a while, it cuts of for a second and then comes back. Now it does this every 5 seconds.

just tested it here. seems to work. The setting was on LOW on my trinity.
I also tried to turn on the GPS settings, which turned on a nice little menu for configuration of the GPS. Looks promising if this is what we get
does not look like the settings gets any gps functionality to be activated besides the settings.
Excellent
Made a big diference on mine too! Nice to know it worked for you.
Try this to disable joint stereo so you get REAL stereo sound, then you will see the difference.

Same here ....
3D surround configuration
On page 78 of Trinity's manual there is an instruction to set the 3D surround configuration at the headset by going to
Start> Settings > Personal > 3D Surround Sound
and enabling surround sound + setting levels.
I simply can't find the "3D surround sound" selection at >Personal tab...
Can someone help me to configure (eventually by using some registry configuration) how to make this command to appear?
Seems to me this could help to improve stereo quality at P3600...

The problem with my new p3600i is that the volume is much too low. With volume control at max setting, I can just hear music in a quiet environment. e.g. an empty room. When there is any background noise, e.g walking along the street, on a train etc, it is almost inaudible. I am mainly listening to classical music, so the dynamic variation is greater than for rock etc., but nevertheless very disappointing.
I am using the supplied headset, but the sound is not loud enough to know what the quality is like.
Are there any setting I haven't found yet? All the talk about changing the ROM sounds like something which might void the warranty
thanks
John
I have used HTC_UseJointStereff.cab and HTweakC, it seems that the sound changes a little, i don't konw which helps, but they help....
Thank you all.
I've searched here for hours and haven't found a fix for this. Unlike many of the posts I've found and read here, I don't have any issues with skipping with my bluetooth earbuds.
On my 8525 with 53 decimal set for bitpool and max bitpool and jointstereo=0 I get tinny hissing artifacts. not worth using.
these are no-name earbuds similar to the itech clip ones. don't know who made em-came from ebay. they worked great with my widcomm stack harrier.
increasing the bitpool numbers further has no effect on these. they don't seem to skip at all though. am I missing another reg setting change?
are there off the shelf headphones that don't skip without the a2dpfix service and work well with hermes? I see mixed answers on many of them.
just when I think this phone is pretty stable it locked up this morning and didn't alarm. I overslept...
I'm also having same annoying hiss issue, afaik only another bt stack (namely widcomm) or maybe new aku update would solve this problem.
don't know where they are going with porting widcomm to hermes,
but hope they have some progress...

Hacks, registry tweaks section of Wiki, search "A2DP" or "stereo". I use sony-ericsson hbh-ds970's and after the tweak, sound as good as my old wired earbuds. Only shortcoming is the occasional sound drop (millisecond or two, but still annoying). Setting PocketPlayer priority to "normal" virtually eliminates the problem. An extreme solution is applying Sleuth's A2DP fix... search the wiki for more details.

You mean skipping issue rather than hissing sound issue ?
-Kha
The hiss is a known artifact of the M$ BT stack. My testing with the Widcomm stack eliminated this issue. However, out of the box version 1 Widcomm tests showed decreased fidelity and noticable buzzing on the high end. However, I believe there's a number of A2DP fidelity tweaks that can be applied to correct this. I will start working on this when superdave gets the handsfree issue solved .
Well, I was unsure if I should post this under one of the old posts, but I decided to start it as a new clean post...
Many are having problem with "hissing" noise, joint-stereo and low bitrate(or bitpool). For my sake, I've tried "fit4cat - Hermes Tweaker", "Sleuth255 A2DP fix" and several other methods, but without beeing able to get the soundquality I want from my headset.
Now, this is what worked for me after tweaking around with the registry a while, and endless pairing sessions
Download a registry editor(I use PHM, http://www.phm.lu/Products/PocketPC/RegEdit/ <- Download the PocketPC 2002/2003 ARM/PXA)
1: Turn off bluethooth on the Trinity
2: Unpair the Trinity with the headset(Delete the headset from the list!)
3: Change the following registry settings:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Bluetooth\A2 DP\Settings
MaxSupportedBitPool=80
MinSupportedBitPool=40 (or more if you want)
(if these arn't there, add them!)
And DELETE:
UseJointStereo = 0/1 (depending on whatever you have put there before)
[HKEY_LOCAL_MACHINE\Drivers\BuiltIn\WaveDev]
Priority256=149
(let the rest be as it is)
4: Reboot
5: Now, DO NOT use the headset for direct pairing!(since you've already added your phone to the headset, pressing a button on it will useually pair it back with the Trinity) <- This seems to be the function that triggers the sound-problem...
Instead, set the headset in visible mode, and use the trinity to pair(search for new devices), when you find the headset and pair it, you will hear the pairing-sound from the trinity-speaker, and NOT the headset.
Now you can enjoy high quality stereo sound without any disturbance
But, the problem comes when you turn off your Trinity, or the headset. If you try to connect the headset and the phone by using the connectbutton/playbutton on the headset, it will pair, but this time you will hear the pairing sound in the headset, and then you have all your problems back... So then you have to turn of bluethooth, delete the headset from the trinity, and add it back once again by turing the headset in visible mode again.
So the solution to this, is to go to the device list on the trinity after you have lost connection with the headset(this is if you have turned of the trinity or the headset), and hold the stylus on it and choose "Use as wirelss stereo" and "use as handsfree"...
Thanks to all of you guys here who have posted solutions to the A2DP problems And if anyone have suggestions to other values that are better fit then the onces I've supplied, share them with us
And if all of this have been posted in another thread that I've missed out, the moderators are free to delete this one
Good grief, I can only imagine how many times you had to pair the headset before you noticed what was going on LOL, hope you didn't turn blue in the face
I imagine a ROM update could fix this problem.

Hehe! The thing that made me going was that I was able to get perfect sound once or twice, and since I made it work those few times I just had to find out what I actually did that made this work (And paying 175$ for the headset also keept me fueled for a while ) hehe!
I think I've used about 5-6 hours total these two days sitting pairing, adjusting settings, rebooting(ARGH!), untill I found out that the problem actually occurs when you use the headset to pair instead of the trinity
I don't understand what is it with bluetooth stereo:
quality is not good enough to listen to music 64 kbps... no bass, no medium, nothing just a hiss.
and plus you get 80% cpu (with a 400Mhz...), just to encode this crappy 64 kbps.
Yes exactly for all people having so many skipping problems check your cpu with taskmgr.
So you cannot play video with A2DP unless you have 1Ghz!!! good for battery life.
If you like music you want good earbuds. There's none with A2DP.
So what's the point again apart from having to charge one more device?

1: Well, I'm not sure on the bluetooth 2.0 specs, so If there is a spec limit on 64kbps, then this is new to me.
2: And the skippingproblem is not just connected to the CPU-usage.. But if you have some info on this issue, then please; do share it with us.
3: A2DP headset with minijack is available many places, even HTC has one. And if you take a look at DS970, you will see that it's the same as Sony MDR-series.
4: And well, the CPU usage is a issue, but that is the only part that I agree with you on..(but let us be frank, I've bought a pair of A2DP headset, so I do smell a bit "conflict of interests" here...)
And to the bottom line, I've bought the Trinity because it's one hell of a gadget, and so is bluetooth stereo So if anyone want to shoot me for that, well hell yeah, go ahead
Edit: And FYI meroupow: I do feel you are a bit rude in the way you wrote that response, or at least a bit arrogant when you post a comment like that. Trying to mock people who have bought A2DP headsets and are tweaking and fixing issues to make them work correct(this also goes for GPS on the phone, black coating comming off, improving camera quality, getting the ATI ImageOn to work correctly... etc) . And I must honestly say that yes, you do have some points there, but you should be able to present your views in a much more polite way...
Sound better but discontinuou. Impossible ear music. The sound goes on and off continuously. Why?. How can I do?
I am sorry if you felt I was being rude.
That was not my point and It was probably the wrong place to say what I said.
It is just that just like you I bought this A2DP stuff with my Wizard.
Just like you I tweaked it as much as I could and managed to get it work.
The problem is when it comes to sound quality is important and just working is not enough.
When you show your happiness because it's finally working, people think you are happy because it's good and they are buying it. And get disappointed too.
I just wanted to warn people on the fact that it's not working to watch movies because of cpu and that a 5$ earbud will have far superior sound quality.
It's just a toy and by no way a mature technology.
I've got a CB2530, hard to pair and I still don't know what do I do for the pairing to be successful, but I do manage to pair it after a few attempts, on the registry I just disable jointstereo, set the MaxSupportedBitPool to 320 and the quality is quite nice and with minimal skipping. High cpu usage of course, but if I set the MaxSupportedBitPool to 80 the quality is quite crappy and the device gets equally sluggish(gets worse when you touch on the screen, as K-Rally does even with the new ROM).
As for the pairing, I still haven't confirmed, but I think the registry setting that enables the bluesnarf option on BTCrawler has something to do with it(the bluetooth ISC mode thing), because right after setting it I managed to pair the headset right away, the thing is, I was also successful in other occasions when I hadn't set that reg. option.
Hearing the pairing sound from the trinity or headset doesn't indicate anything on my case, and I think I've already tried these reg settings you mention, but I'll try them again as soon as I get home to see if there's any difference and post the results.

Does anyone know what is changed when you DO pair with the button on the headphones? With some models, you MUST do it because, otherwise, the music will be muted after about a second (see http://forum.xda-developers.com/showthread.php?t=282008 for more info).
I've searched around in the Registry for changes, without any success. It's possible we could directly edit the headphone connection-dependent parameters set AFTER the headphone's initiating the connection to avoid sound problems. If we knew where they're stored, that is.

BTW: is it the profile and software on the phones/PDAs that arn't handling it, or is it the standard itself that sucks? (or in other words, should I keep my headset for later usage or return it to the store)
I use Plantronics 590a and the skipping problem appears very rarely, mainly when I use volume/track buttons on headset. However, yesterday I also connected the headset to a normal stereo (via the 3.5mm adapter) and noticed the same occasional skipping. So in my opinion the skipping issue problem might be from headset, not Trinity.
I also tried a Nokia stereo bluetooth headset and noticed serious skipping problems - unusable.
PS: there is indeed a skipping problem if I open/close other applications while listening to music. It looks like the processor is very busy - system very slow etc.
PPS: any suggestions for a player that has equalizer? WMP doesn't and the sound is not that great (especially when compared to my old SE P900 which had an excellent player - best I've heard so far... )

Stereo BT experience is very positive
Hi all,
As always, someone has to have a different view of the issue. I got my trinity a couple of weeks ago and went and bought a Plantronics Pulsar 280 stereo headset. Mostly because of the stereo jack. I have not updated trinity nor have I applied any fixes, just paired right out of the box, as always from trinity BT manager. It really sounds great, particularlly the base is fantastic because of the earbud design. Even you may choose the actual headset of your dreams by using the standard 2.5mm jack. I have owned a "no brand" headset (still do) but it is not BT 2.0 and I think it makes a difference. The plantronics does not skip and it sounds great. Most of my MP3 is 128k and above so no limits with that. I have not checked my registry settings as they are default rom image set. I am using ROM 1.15.412.2 and Radio 1.20.00.11 (my trinity only speaks spanish for now, hope to change that soon).
Point being that the software and quality of the headphones makes all the difference, don't be so quick to blame trinity, just a piece of my mind. Keep it up guys!!!

If you tell me how I'll be glad to try...
I've never managed to do it sucessfully with my Prophet (witch had the same A2DP sound quality problem as it come with taht Fu***g, crappy, buggy, foot-coded MS BT stack)

Yes, how do you change the BT stack on the Trinity?
Thanks.

If you haven't changed anything it might sound great but it definitely sounds MONO!

Up to now, I haven't managed to do it; see http://forum.xda-developers.com/showthread.php?t=291605 and http://forum.xda-developers.com/showthread.php?t=286094 . Sorry for telling you it might be possible - I assumed it would, as it is on most other HTC models.

set UseJointStereo to 0
I am trying Touch HD with a Jabra 620s, A2DP (stereo headset profile), but I suffer occasional music skips.
I have read numerous thread about this problem, and habitual registery fixes like Priority256 etc.. doesnot seems to work with Touch HD.
With Bitpool=30 I have no skip, but sound is awful.
With Bitpool=40 I begin to skip. JOINEDSTEREO=1 helps a little.
I have not tried all Bitpool values below 40 (painful, softreset etc..) but Bitpool=40 is minimum quality IMO.
I tweaked Priority256 (/HKLM/Drivers/BuiltIn/BtA2dpSnd) down to 1, with not much improvement.
I noticed also turning Wifi off helps, but it is no sufficient.
Does anyone of you use A2DP ? Do you have problems ? Thanks for your help.
i use it with the Sony Ericsson DS980 and i dont have any problems at all.. the only thing i notice is that the screen turns on every time i change the song.. any way to get rid of that? want to save battery lol.. ..
I get skips too. Haven't figured a solution yet.
I'm using Moto S9 stereo BT headset, I have the same problem......
And I noticed, when I start play music, and press the powerbutton make the HD enter the blackscreen mode, the quality is good, and music play very smooth, but if I press powerbutton again make the HD back to normal status, and screen on, big stutter occured, and after some seconds BT lost connect with HD......
It's a little outdated, however have you used Sleuth's A2DP fix?
i always got skips with a jabrabt620s and a trinity...well you can minimize it - but never get totally rid of the problem....this is an A2DP limitation, sensitive to EMI like wifi etc.
My suggestion: go to wires...
Skipping?
I've been using a Votager 855 A2DP headset for 6 or so months with Pocket player. It's an excellent application, complete with A2DP compliant equalizer.
I listen to head banging music, but it never skips...but maybe it does and I just don't notice between the bangs.
In another forum several months ago a person or two took up my suggestion on the PP app, and had good results with a stereo BT headset.

I've seen it, but not installed it for two reasons :
1) It isn't validated for WM6 nor for Touch HD
2) It seems to eat CPU time too much, according to certain posts
Thanks for the tips anyways. If someone more daring than me installs it on Touch HD, keeps up informed.

A lot of people have problems with A2DP, but a lot too have none. I'm pretty sure problem comes from poor BT stack, not A2DP technology itself or BT broadcast / EMI problems. I've almost the same skipping rate with my headset 30cm from my HD, than 5 or 8m from my HD.
Your suggestion is wise, but I'm eager to make my Christmas present functionnal..

I've just downloaded it and tryied it. For now, no skip at all !!! (with BitPool=42) This application seems to be very optimized for A2DP.
I keep you informed in this thread if this resolves my issue. I want to increase Bitpool to 50 or more to have optimal quality (I listen classical), and I hope PP will handle this datarate.
Thanks for this excellent advice audscott.

I also have had no problems using the HBH-DS980 except that I too can't get it to stay in 'standby mode'.
I started a thread on this exact same issue, but have had no joy up until now.

Any help or pointers in the right direction would be greatly appreciated.

dear all,
i remember searching up for ad2p anti-skip quite a few months back.
my conclusion was the following settings:
jointstereo -> turn on
samplerate -> 48000
remove all bitrate settings
then all should be well.
The previous settings that involves bitrate, priorit256 are meant for wm5 devices.
in wm6.1, most of these are redundant. in my case, the above settings works perfectly on my itech blueband pro. ad2p and avcrp works well with the default player or with wmp.
Where can one find these settings? I have looked high and low!
***Doh! Found them... HD Tweak is my friend!***

I also have iTech BlueWhatEver and it works better, but still ones a few minutes sound skips
Also how to prevent phone from waking up from standby when I press pause/ff/rew button? Because it's ****ing annoying, I have to manually turn phone back off, so avcrp is totally useless if I have to touch the phone.
I suggest you lower the bitrate to 44100. 48k is useless since your mp3 are in 44.1kHz and you will save some CPU, bandwith
Jointstereo = 0 is prefered for quality purposes.
Then the bitpool ... this is where it gets tricky because every headset have their own limitations.
When i use it with my sony ericsson HBH-IS800 I can go up to 48.
If I use another device I need to lower it to 40.
The "CPU" of you headset needs to be taken into account.
The touch HD have no difficulties encoding SBC in realtime in high bitrate, the issue comes from the headset itself not able to decode SBC fast enough according to the bitpool you chose.
So there's nothing you can do except trying another BT Stack (that can have better SBC encoding algorithm) or changing you A2DP headset.
