Taskmanager fixes BT Stereo skipping problem!?

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?

Problem With BT Stereo Headset

After upgrading from WM 2003SE I have not been able to use my BT stereo headsets. I have both a Motorola S9 and a Jensen WBT212. The music from audio manager or WMP will start but then it will become choppy as if the connection is going on and off every second. Didn't have this issue with WM 2003SE. When used as a handsfree headset there is no issue. I also noticed the elapsed time of the song in progress is also erratic. This happens to both media players. When the BT stereo headsets are not used both players play normally. Anyone else having this issue? Any ideas or resolution would be greatly appreciated.
Device : Siemens SX66(WM6)
ROM Version : 5.60.00 WWE
ROM Date : 03/02/05
Radio Version : 1.15.00
Protocol Version : 1337.45

I finally got the bluetooth headset to work by installing the Helmi BT CAB for WM5 I found in the WM% forum. It is kind of strange now that it seems l;ike there are two BT connection managers but I can now get the headsets to coneect properly and the media players seem to be working properly too.

Hi I have that weird skipping problem with my HT 820 motorola stereo BT It's not really bad but it shouldn't skip I think. could you send my a link to that cab? any help appreciated.
Thanks Gyurma

BA WM5 Broadcom 1.7.1 Build 3400 Stack (Test) is the title of the thread.

which one?
thank you,but I found it,but there are several patches and stuff over there one of which (BTStack.zip) I do not know how to install which one did you use?
thanks again

I got my new BT headphones yesterday. Charged them all day. I did the pairing thing last night. They worked great. Fantastic. The audio was crisp and clear. I was able to answer the phone with them, and again over the phone the audio was great on both ends. But it's like that poem about the girl with the curl. When they're good, they're very, very good. But when they're bad, they're horrid.
I've spent the entire day fighting with the BT. It seems that I can use the headphones only right after I pair them to the device. If I shut them down or turn off BT, when I go to restart, I get the choppiness that's so bad you can't even understand what song is playing. Resetting doesn't fix it. If I uninstall the headphones, turn off BT, and then do a hard reset and reinstall the headphones, I can use them again and everything is perfect. Until I turn them off, and then it starts all over again.
What is causing this?
I know I could just install the Broadcom BT. In fact, I did today. Twice. The problem with that is that I can only get it to recognize the headphones as a high quality audio device, not a headset phone device as well. I can install it as both, but they don't play nice together when I do, and if I install it only as the high quality audio, I can't answer the phone with it. (And yest, I did install all the patches and addons I found throughout that thread.)
Also, the Broadcom audio quality isn't as good as what I'm getting with the MS. Almost like the difference between an mp3 encoded at 96kbps, rather than a better quality.
I've tried the A2DPAudioFix. No help there that I could find.
Am I missing something?
Is it really a choice between crappy audio quality and no phone headset functions and having to hard reset my device over and over?

Same exact problem
Just upgraded the radio today to 1.15 and rom to WM6 last week - Bluetooth stereo headphones work ok for phone but not for music. Please can someone posts links as to where I need to look for various cabs - I've tried searching the forum but am not having much luck. Just happened to stumble on this thread.
Michelle

Stereo bluetooth works now
Well - my dh is sick of me working on this - but I know how BT stereo headphones that work w/ audio and the phone.
I am not even sure what I did other than install every cab I found and I'm sorry I don't have links-
RestartRadio.exe
BroadcomCorp_BT1.0.0.3900.cab
RestartRadio.exe
(still had problem w/ scratchy / stop / start)
then ran
ba_oem_audiogw.cab
and
BroadcomCorp_BTUpdatefor1.0.0.3500.cab
but I don't exactly the order of the last two - I am not even sure I ran the audiogw.cab - anyway, it was like magic - stereo sound minus static and skipping.
This is after flashing to wm6 and flashing the radio to 1.15 - and there was something else I tried - oh, I did change the registry to 64 from 128 I believe - the SD card entry.
Anyway, it's been a long day - now I'm off to figure out how to change the 72M B free in Program to give some to storage which only has 5.48 free.
Michelle

Mgrunk- Which SD card entry did you change? Could you kindly check to see what version of BT you are now on? Start/Settings/Connections/Bluetooth should get you to the version. I have mine working like I described earlier using the HELMI WM5 Broadcomm 1.7 cab, however still have periodic static and skipping. I am curious because my BT headsets worked well with WM2003SE and BroadcomCorp_BT1.0.0.3900.cab. Thanks in advance for any info.

http://forum.xda-developers.com/showthread.php?t=329998&highlight=SDCARD+SDMemory_Class
is the link where I found it.
hklm/drivers/sdcard/clientdrivers/class/sdmemory_class is the entry and it was 128 and I changed it to 64 per another mesage - it did clear up the stuttering problem w/ AudioManager and WMP.
In regards to the version - now I have to BT icons on the Connections page - the About on the second icon says PE "Version 1.0.0 Build 3900"
But last night I deleted AudioManager and then had the horrible BT stereo headphone problems - I also noted while WMP was playing, it sucked the available program memory down to 5M - didn't matter what I started w/
I reinstalled AudioManager - no luck w/ BT, renistalled all the BT cabs
BroadcomCorp_BT1.0.0.3900
BroadcomCorp_BTUpdatefor1.0.0.3500 - oops looks like that probably was unecessary
HTCHeadset_AddOn
ba_oem_audiogw
But, I have persistant problems - if the ppc turns off - when it comes back on, BT icon shows on, but there's no BT. I have to go into CommManager and uncheck handset and headphones, click save, go back and click them back on and click save and then start audiomanager up and play music. But, I found that even w/ that I had to repeat the whole uncheck the services and then recheck them - somehow it's different than turning BT off and then on (that didn't work at all)
*** hey this morning the BT stereo headphones worked fine w/ AudioManager - didn't have to turn anything on or off - once in a while there's a short pause in sound but otherwise it sounds fine.
*** for no reason, BT stereo headphones are back to non-functioning - tried soft reset, reinstall cabs, etc. - no decent sound out of them - of course they work great for BT phone. Any suggestions?
I was a programmer in my former life (before 8 kids) and I design websites, but I was totally frustrated w/ the BT issue - so I'm not being methodical and I didn't really find a definite thread that said do 1, 2, 3 - so I've thrown every cab I can find onto my system.
I'm sure this doesn't help - it's very scattered and unorganized.

Mgrunk. what Broadcom do you have installed and where to get it? In WM6.0 there isn't an "about"
meanwhile found the Helmi BT 1.7 but I am getting a insufficient driver memory available. I have to preform a soft-reset which I did but didn't help. Whats is the solution?

Give up
ok, it's back to not working - I'm going to return the stereo BT headphones and wait for a new answer - maybe it's the headphones.
But, in regards to the about screen - I had 2 BT icons on the Connection page and the 2nd one had an about page - I hard reset today and it's gone.
Michelle

Mgrunk- I hard reset a couple of days ago as well just trying to cleanup because having two BT connection managers was bothering me. I have gotten the MS stack to work better by doing the SD card registry edit you suggested and another one at HKLM\software\microsoft\bluetooth\a2dp\settings\bitpool and setting it to 25 then settling to 23. It was at 48 when I started. The lower the number slows down the data transmission rate and reduces the choppiness. The lower the lower the sound quality as well so you will need to adjust on your own. Start with 25 then work your way down. What headset were you using?

Well that worked sort of
I changed those 2 registery values - I had to take the bitrate back to 21 - the sound has really degraded - but the music plays - who knows if it will work tomorrow.
Oh, and I have a set of Spider BT stereo headphones - the people I've called said the sound is fine so the mike works ok and the sound is great for the phone.
They're behind the neck, over the ear as opposed to earbuds but I didn't want wires. The ones I really wanted were $129 - earbuds behind the neck.
Michelle

I've been able to keep my BT headphones working by deleting the entry and forcing them into pairing mode and re-pairing them whenever they get choppy. If I'm careful about how I shut them down and restart them (shut off music, wait until I hear the headphones stop transmitting sound, shut off headphones, shut down BT -> start music, start BT, start headphones) I can use them several times before I have to re-pair them.
But it still seems very weird to have to go through all this crap to use them. If I deviate from that shutdown and restart pattern, I have to re-pair them to get them working properly again. If I do a soft reset, I have to re-pair. It can't be the headphones. They work great with other BT applications.
They do work fantastic when they're working though.

a link from a different forum
http://pdaphonehome.com/forums/ppc-...-rom-only-read-1st-post-before-posting-7.html
so, now I'm off to convert some of my music to mp3 - and then I'm going to try some different players - AudioManager has the same issues w/ wma music as WM10 player - having the bit rate down to 21 really makes for some static in the music.
Update: didn't work - low rate mp3's w/ MortPlayer had same issue

HBH-DS970 Bluetooth problem / HT820 review

I'm having problems with this stereo bluetooth headset. I can pair with it fine from a few meters away but I can't play music from it unless my phone is almost touching the reciever phones
I think i've tried everything, been through a hard reset and installed the bluetooth hotfix but no luck.
Any help would be appreciated.
Thanks superman101
EDIT: I couldn't fix the connection problem so i returned them and just ordered a pair of ht820 i'll let you guys know how that turns out

HT 820
I got my ht820s today and all i can say is that they are AWESOME
The range is incredible i can get the advertised 10 meters (33 feet) with ease, and indoors the signal rips through walls
Most of the buttons work answer/reject, call hold, answer 2 calls + switch between or merge them, redial numbers, dial a number using voice command
(not sure is msvc will work as i don't have it, if someone does and has these headhones i would appreciate it if you could fill me in as i would definately be interested in msvc if it works with these)
The battery is great too with 17 hours call time, 12 hours music playback and 500 hours standby, I'll update what these actually are when i have tested them fully.
The soud quality is also ace and all music buttons work with audio manager and windows media player (probably most others aswell) The problem that some people have that the music will play through speakers doesn't happen either. Loud as most people will probably want but the base is not the best i've ever heard but great for wireless headphones.
Very comfortable with ear hooks and no pain whatsoever after 5 hours, they will not fall off when jogging or in the gym as they are very secure ( Ijust couldn't shake them off)
I got mine for £17 from ebay deliverd and new (amazing value in my opinion) i recomend these to anyone who wants great quality headphones that won't break the bank, worth much much more

Do these headsets have USB charging or some proprietary charger is required.

Charger
They use a standard mini usb charger so the tytn II charger will work along with the usb connection and any motorolla mini usb chargers you have

I have been using this setting after experience disruption and range issues, and this setting fix all the problem i know. except display song play and name of caller.

what kind of software to edid the registry
what kind of software to edid the registry
thanks

Registry Edit tool
google PHM Registry editor, best tool, can be install into external memory card and in the event of hard reset your phone you can go to storage card directory under program folder and run the registry editor without reinstall. Good luck.

I use the DS970's as well. To answer calls through the headset, its best to hit the play/answer button on the lanyard instead of hitting the answer button on the phone. Not sure if its supposed to be like this, but honestly I prefer it. That way i have the easy choice of using the headset or not when the phone rings.

I recently upgraded from a Nokia N95 to a Touch HD. I've been trying to get my Sony DRBT21 bluetooth headphones to work with the touch HD. The phone pairs with the headphones, but the sound quality is poor with no bass and sounds crackly.
Additionally when I turn off/on the headphones, only the headset and microphone profiles connect back to the phone, not the A2DP stereo part. The only way I've found to get it to reconnect is to repair them.
Any idea if this is a known issue with A2DP headphones on the Touch HD? I'm not expecting to get brilliant audio quality, but as it is right now with crackles and distortion it isn't worth listening to.
Just wondering if anyone has any ideas on how I can fix or optimise this?
Cheers

Was the device properly paired? Were you prompted for the PIN? If not, do so manually by going to Bluetooth settings and pair the headset from there.
As for the A2DP not being available when reconnecting, this seems to be a known issue as I experience this intermittently with HTC's own Bluetooth and another third-party one, too. This issue was also observed on my previous HTC Polaris! A workaround for this issue for me is to power off Bluetooth and then power it back on: not a good solution!

It prompted for the PIN which I entered, and looks to be set up correctly. The main issue seems to be the background static when listening to music (hissing and crackling). Is there anything in Advanced config that could be tinkered with to try and alleviate the problem?

This won´t help you:
My Motorola S9 and HT820 (Both A2DP/AVRCP) working fine with HD and Diamond. Also I had some difficulties reconnecting the first times, due to the not used pairing-PIN. The motos doesn´t need it. The HD and the diamond needed some time to accept this
Now they reconnect as Hedset and Stereoheadphons.
Maybe there is another BT-Master (your old phone) active that occupies the A2DP connection with your headset.

I have one HD and S9, sometimes it's a little hard for them to connect but the sound can be very good, the only problem is that with high BitPool values above 30 (medium quality) it's very easy to break the sound when the HD is in our pockets and we are outside the house.

hi, im using the same headphone with you. you got that cracking noise with no bass because it's playing via the headset function, not as stereo headphone.
try disable the heatset option in the bluetooth, then open your music player and try again.
And yes, when u turn off your headset improperly. i.e. turn off from the power button, and not through bluetooth -> disconnect, then turn off... you will have to go to setting -> set as stereo headphone...

I had a play around with Advanced config and found that if I change the max bitpool from 30 to 50, the crackling and static disappears. It seems better now. Many thanks!
Edit: Changed to Max Bitpool 80 and Min 65 and the quality is brilliant. Found some further information from a post on another site (PPCSG) which may be useful to any with a similar issue:
Using ACT (Advance Config Tool), go to BLUETOOTH:
*below are my settings->
-Use Joint Stereo: Yes (default)
-Bitpool: Very High
-Max supported bitpool: 80
-Min support bitpool: 65
-Sample rate: 48000Hz
*My settings may not be the best, therefore you may want to trial and error.
The following shows the named values for the A2DP\Settings key.
By default, A2DP uses a bitpool of 48. A lower bitpool value improves system performance. Increasing bitpool to a higher value causes an overhead on Bluetooth and system resources.
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
-The maximum reported bit pool value, which can be negotiated with the peer device. Default value is 80.
-The minimum reported bit pool value, which can be negotiated with the peer device. Default value is 14.
-SBC sample rate to use. Default value is 44.1 KHz.

least of your worries...
what bothers Me more is that the old A2DP bug from the HTC Diamond has made its way to the HD ROM, in that if you listen to music via A2DP and recieve a phone call, you take that call and end that call then your music continues playing through the phone speakers! You have no idea how embarassing this is on a train!

that doesnt happen on mine, go straight back to my headphone again...

Even though it doesnt happen on mine, to be safe I plug a dummy headphone jact to the phone so even if bt gets disconnected, no sound goes through decice speakers. Makes me feel comfortable on the train. This was also an issue with Cruise which was addressed by a hotfix later on.

Tried that, and the difference is staggering!
I can now confirm that it isn't a hardware issue, that these phones (Sony HBH-IS800) are capable of sound quality just as good as other Sony in-ear jobs. Thanks for that!
Now, all I have to do is try to sort out the drop-outs. It seems as though the slightest barrier can cause drop-outs, for instance, putting the phone in my jacket pocket, or passing my jacket sleeve in front of it. Not sure whether it's the particular material of my jacket, or the metal in the buttons, or what, but it's hugely irritating.
Funnily enough, seems to make a difference if I have the connecting wire behind or in front of my neck. More to follow on this one....

noise ?
For people using the HD and motorola S705 as bluetooth A2DP : do you have also an annoying background noise when listening to quiet music ? Or before the sound starts. You know a noise like pffffffffffffffffffffff

HTC P3600
Hello,
I already installed the tornado_a2dp.cab on my PDA HTC P3600 with WM5. but I can't sincronize MP3 (Windows Media Player or TCPMP) with my headphones Nokia BH-206.
Anybody help me to solve this problem?
The mp3 sound only worked (10seconds) in Windows Media Player when I press the button to do a call

Hi.
I have done the changes mentioned in this thread and got much better sound when listening to music.
But i still have a static noise when im in a call.
Is there a way to fix this?

I am having the same problem as you on my HTC Incredible. Any idea of an app that lets you configure those settings for Android?

A2DP skip : any solution ?

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.

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.
