Hi to all,
as pointed out many times in various XDA forums - there is a definite solution to the skipping problem with bluetooth stereo. The reason i post it again is that i never had the issue before, but it appeared with the latest ROMS 2.26 and beyond - probably due to more optimistic assumptions about the BT headset performances (i own a Jabra BT620S which i love, after i got rid of the Motorola HT820 because of terrific skipping that i could have probably solved!)
The solution:
set/change the registry BitPool (it is a DWORD in case you don't have it) by using TotalCommander or similar:
HKLM/SOFTWARE/Microsoft/Bluetooth/A2DP/Settings/BitPool=40
A value of 50 or so means heavy skipping, the lower it is the lower the bandwidth between your headset and the wizard. At 40, i can be the famous 10 m away without any skipping with a great audio quality. But at 50, i have essentially to keep the wizard nearby my ears....
Last comment on the quality: i don't notice any difference, probably because my WMA files are encoded at lower bandwidth anyway....BTW, MaxBitpool and SampleRate, experimentally, have no visible effect (probably depending onthe MS implementation of the BT stack).
All the precise information supporting this empirical evidence is available in (see for example pg. 22 and 71 for the bandwidth estimation)

Enjoy the Wizard!
No Skipping at last.
It seems to work for me no skipping as long as I am not syning via bluetooth.
Thanks for posting this fix, as the skipping has been bothering me for a while.
I thought it was fixed
Sorry Buddy it still skips on me, do I have to reset the wiza after adding the registry setting?

Absolutely yes, you have to soft reset your device (keep pressed the power button or use the stylus in the small hole on the right side).
I use resco registery editor and there is no file for settings or bitpool? I have cingular 8125 and jabra 620
same here, i have no settings/bitpool in my registry
i have hklm/software/ms/bt/a2dp/devices/1, 2, 3, 4
@pzucchel, which rom are you using?

And your roms are A2DP enabled? seems strange, though you could always add the settings, but God knows how many other keys you'll be missing.

I'm currently trying wm6 underground, in my first test the bt stereo semmed beetter than the others i tried - but i'll see how it survives the work commute today/
which are you using, my only requirements for a rom are -
1 working a2dp
2 fast i don't really care if vanilla or not
Just overclock mate!! No skipping at 260MHz

if only that worked
i am using phoneAlarm which seems to slow down every rom is use a lot, but overclocking does not work for me.
someone please tell me which rom they are using, that way i can try it, and if the sound still drops, i know it's my device/my loaded software
I'm using Core2.0 (as shown in my signature). But I got the hissing problem so I am using Axim Widcomm stack.. However, I still have to overclock to get rid of the skipping. The reason could be because I play aac+ files using TCPMP. I remember that there was no skipping in WM5 when I played MP3s.

Well I'm using the stock T-Mobile now (I'm in between cooks, and messing around with the registry files, hopefully tomorrow I'll be flashing..... again) Have you tried Faria's roms? a2dp worked pretty well for me using an IOGear stereo headset. Skip's were far in between, that is if they were present at all; usually when I had a lot of apps running, or when the phone was connected or connecting to GPRS was the only way it would skip. Your milage may vary though, but it might be worth a shot.
so i flashed the core 2
edited the registry (set it to 20 hexadecimal, which gives 32 in brackets) (i really didn't find a2dp settings in any other rom i tried) and now it works, so thanks for all the help - it's easy when you have the right rom
I thought I would drop in my .02 cents. I have a Jabra 620 as well. I had previously used Molski 3.3 crossbow lookalike rom (WM5). With that one, auidio was good but was not in stereo.
Now today I had some free time so I decided to try a wm6 rom or 2. With Faria's rom, the sound quality was good. I think he sets the bitpool to 60. But the rom itself is buggy.
Next I tried crossbow reload 1.7. This rom is much less buggy. But the stereo bluetooth sucks. The sound quality is very tinny. Also, there is this constant background clanging that is very annoying. I have looked at the bitpool. Bitpool in reload is 30. I changed this to 60 but it may have only gotten slightly better. Sound quality still sucks. To note, I dont get any skipping, so Im happy about that.
EDIT: I decided to change the MaxBitPool value to greater than 30. At 35, all the clanging and general bad sound went away. I'm happy!
sorry for the missed replies!
....i have switched to the trinity due to a wizard failure!
...If you don't have the bitpool register, you should create it. And by the way, i had exactly the same problems with the trinity and the same jabra bt620s, and changing the bitpool value worked again!!!
all the best;
Piero
I now have the ingenetics rom dump flashed to my ppc (see my sig) and it is by far the best a2dp rom ever - without overclocking (i forgot to try it, so i'll be doing that soon, to see what improvements i can make)

OT - how is the trinity compared to a wiz? i asked in my local shop, but with all the rubbish from orange on it, it was actually a lot slower than my wiz. and they wouldn't even let me hard reset it and let me remove the extended rom they even said there was no other software to make it run faster! nor would i be able to remove the orange crp - funny how we know more about these things than the sellers
Thanks for this post. I know it's been a few months, but I just got myself a Jabra BT8010 and this change in the registry value made a difference in the audio quality. I don't have the drop outs I had with the other value. The problem I have now is that TCPMP doesn't play the video smoothly when using the headset despite overclocking. Any ideas to the setting that would help? Thanks.
Re Skipping
Hi All
I just got the 620,s , and Yes they sucked, found this fix , (post 1) tweaked my registry , soft reset......
And OH MY GOD !!!!!!!!
It works FLAWLESSLY,
hasent skipped now in 30 mins, walked away from phone 20 feet, not a skip in sight
You Guys , Totally Rock!!!
Kudos to the poster
First post so go easy guys. I was able to flash a ROM and a few other things with no questions using search and just doing the leg work. I am sure the answer to my question is right under my nose but I haven't been able to word it correctly or something.
I have a Tilt using Dutty's 5.2.19716ROM (4/29/08). I am also using radio 1.65.14.06. I never changed it because everything was working rather well and didn't see the point.
Here is my problem. I have a motorola S9. In it's profile it is showing both wireless stereo and hands free. Ok now sound is actually very good and range is nice but it is not in stereo. I can maybe hear just a twinge of music in one ear but I am not sure, the other sounds like a champ. I can hear and answer incoming calls but no one can hear me on the other end. Lastly I can answer calls and use the volume keys on the headset but not any of the media player controls work, (next track, previous track, play/pause). Also skipping or lag is there but not that bad at all.
I tried the setting suggestion in the registry that was supposed to be set to "0" to turn on stereo but it was already at "0". (sorry forgot the path).
Thanks so much for any help in the right direction.
I am thinking about changing the radio. Also I am going to test the headset to make sure it isn't the problem. I have seen that most people haven't noticed any difference by changing the ROM. Anyone think it could be a radio issue?
I feel stupid as I tried to test the headset right away but didn't have a phone that was A2DP capable handy. I got my old phone a Sony w580i and set it up with the headset and it had the exact same problem. I am assuming that it must be a faulty headset? This reminds me of real life. I am talking to myself and answering my own questions.
thats the way to go... step by step troubleshooting...
Hello guys.
I have a Plantronics Voyager 815 mono headset, which is supposed to be a rather good one. The reception quality is great, however people on the other end either don't hear me very well, or they're telling me it's as if I would talk from inside a barrel.
I usually hold the phone in my hand, so it's barely a meter or so away from the headset. When I just use the phone (no bluetooth), the sound is crystal clear both for me and the other side.
I was wondering what your experience might be with bluetooth headsets and if you could perhaps recommend one that would also have a good outgoing sound.
Thank you.
Hi pedmond, I use a motorola S9 mainly for music, no one ever phones me unless I'm at work or my Mum, But I love it, the sound and reception are great. I did have a problem where the sound kept dropping out for a few seconds then coming back but it seems sorted since my latest flash (Dutty's 1.6 awesome). On the S9 the mic is built into the tiny in-earphone in a single unit, background noise is minimal. One thing I did was play with the settings in Schaps adv. config. until I was totally happy, I know you must have done this, and searched everywhere and also posted in accessories too! Maybe you have fluff in the mic!
Thank you for the input, uniqueboy.
I played indeed with Schaps settings, but unless I'm mistaken they are for stereo headsets - mine is mono. Your S9 would be too big for that.
I'm mainly using it at work for business conversations; I also need it to be small enough to keep in my pocket.
The headset I have has an extending boom, which makes the microphone hole pretty much self cleaning, so I would guess there is no fluff (at least I can't see none).
It's a bit annoying I can't use my set in optimal conditions. I'm willing to buy a new one, I just don't want to get into a trial and error loop - this can get expensive pretty fast.
I also don't trust a lot what I read on the net - this headset comes highly recommended, but I find this not to be true.
I would thus rather learn from other people's experience.

hi bro,
I am using Jabra 5010 mono headset as well as I-Tech Blueband Pro stereo headset. Both, i do not have any problem with bluetooth and sound/voice quality.
not to jump into conclusion that your set might be faulty ... Have you done any tweaks to increase/decrease volume? if so, try to reset to default. or try another rom, if using a official rom or cook rom gives the same issue, then most likely it will be your headset thats causing the issue.

OK, this may be a silly question: can I increase the OUTGOING volume on a bluetooth headset? (mono)
Just to mark this problem solved: turned out my headset was defective. I've had it replaced today and finally everybody can hear me just fine
Thank you for your help.
Anyone here could confirm if SRS WOW HD work on X1 ?
it does work, however it screws up the volume control. Also, sound doesnt seem much better, its realle, really good as it is
That's sound great
Wow that's what I really want to hear thank for reply
Anybody get a version of SRS Wow to work on the xperia?
one version said it couldn't load the driver, and the other version worked but you couldn't change the volume settings (always set on a very loud setting).
How did you get it to work?
I installed on my X1, but no sound, and phone can't wake up after sleep(gotta remove and reput battery).
I realised my wave.dev is missing, can someone please upload it?
I tried the one from this thread: http://forum.xda-developers.com/showthread.php?t=421589
It works, but sound is VERY loud and volume control doesn't work any more.
Anyone has been more successfull than me?

HTC Audio Booster ... !
Hey!
The attached HTC Audio Booster works great on the X1 !
BUT the graphics are made for QVGA so it looks a bit tiny.
I can live with that
Greets !
It will screw up the switching of the sound channel.
I did try the SRS Wow and found that it will screw up the switching between sound channel. e.g. A2DP -> Headset (phone call) -> turn off BT, and you will found there isn't any sound on yr speaker.
For HTC Audio booster, it only works for wired headset but you can use the files from blackstone for WVGA resolution.

I have also tried it. It works but it automatically switch to internal (Stereo) while i want to keep it in handphone....
it there any solution for this bug?!
I´ve tried it with the attached .cab. In my opinion it was a very bad experience. I´m using Grado SR80s which sounds very good with everything EQ turned off. With SRS Wow HD the sound was less detailed and lacked definition.
I think it can sound better with bad headphones (compensating with EQ) but I can´t recommend it if you are using good ones.

Ummm...I use it for making ringtone become louder, so sound quality is not my concern. The headphone mode of SRS WOW is really work. I really want to know how to slove the problem of switching to internal (stereo) automatically. Anyway, thanks for your opinion
A simple question: on which way is the sound better (when using headphones and SRS Wow 3D)?
Would be nice with a description.
For me the biggest problem was the lack of definition and details compared to totally flat setting with the Pocket Player. But - if SRS Wow HD has an own audio driver who has replaced the standard one - it sounds good when it´s used in "flat mode". But I´m not sure it has replaced the standard audio driver (i.e it´s always used instead).
Any X1 user successfully install and notice changes in the speaker after install this SRS WOW HD ??
Anyone mind to upload their Original WaveDev registry here?? My X1 totally lost its sound after install SRS WOW n their wavedev.reg zzzz
it works easily without any issues.
it digitally loudens the sound...if u amp too much..u get distortion..but otherwise u can use it for loudspeaker
am confused.. so bottomline which is the best free audio enhanceR?

Please, some body tell me how to increase volume of internal speaker? my TytnII's internal speaker volume is small, i can't hear when i'm in the street! With my Treo 650 this problem can fix easily with "Volume Caze" software, what about Windows Mobile?
thanks!
Well in this day and age, get another phone. No offence I just had to say that.
have you tried the obvious roll up the wheel while your in a call (rtfm). thats as loud as it goes
otherwise you could always get another phone (theres an echo in here)
I see a smile here.

What Rom are you using? TPC had some volume hacks for his Roms. Not sure if they will work in others. Some of the hacks had a tendency to mess up bluetooth audio, but you can try it at your own free will.
Just extract the file and copy to you Windows folder using a file explorer like Resco File Explorer. I take no liability if you mess up your device though. However I have personally used these hacks and I already stated some of the bugs they have.
Interesting... I just determined today (day 2 of using TPC's Mega Minila) that my in call volume is DEFINITELY lower with this rom than my previous (KAIS_ROM__eOS_4_888_FiRe_pp6__NoRadio).
There must be something up with different roms.... I'll give these hacks a try I guess.
Same here with TPC's Mega M2D
I have the same volume problem using TPC's Mega. I was gonna try switching radios and see if that would help, but other radios dont give me the signal reception that I get from the one I'm currently using. Have anyone tried any of these three on TPC's Mega Manilla rom, and if so, which one is the best volume level of the three, and does bluetooth audio suffer? And if I try one and decide one of the others is better, or decide I can't use any of them, is it as simple as removing it from /Windows and soft-resetting, or will it change some registry stuff or something ?

I have used these with TPC roms and they work. TPC's default is the normal one. You can try the louder & loudest, and if you don't like it, copy the normal one back to the Win dir. I have a Jawbone Bluetooth headset and I experienced some audio issues. But you can try it and see. If you have problems, like I said just copy the normal one back to windows.
it works! Also the quality of the sound isn't too good but it's ok (I've tried the loudest)! Thank Philux-X!
