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
hello again everyone!!!
i just got a set of blueant x5i stereo bluetooth headphones yesterday... they look cool and feel cool... call quality is great...
but the mp3 sound through my tmobile wing is HORRIBLE!!! i tried the headphones on my co-worker's t-mobile dash and they sound awesome... i can't figure out why they sound so muddy and crackly on my phone... is there a setting somewhere that i am missing??? perhaps a firmware upgrade for my phone that would solve this issue???
any help or insight would be greatly appreciated...
thanks in advance,
bennie
How does playback sound through the included (if any headset) or through the loud speaker? If it sounds good (normal) through those then its most likely a blue tooth problem. When you sync it up are you around anything that could possibly interfere with it during the sync process? There have been a few times when I am making a call (rare) but it wont get a good connection and everything will sound like I am under water or worse. (more with my old phone having a crappy radio)
If you have sync'd the two a fair ammount of times and its always the same sounding quality might look on the T-Moble Wings forum (this is the HTC s730) and see if other users have had the same problem. I wouldnt see it having a bad HTC driver, but it might not be very compatable with that headset?
its hard to judge sound the the loud speaker... it sounds bad no matter what...
when hard wired through the headphones that came with the unit, the mp3 playback is fine... its not crackly like this headset is... i tried resyncing a few times as far away from everything as i could so there would be no interference... i never sync my music files though bluetooth so i know that the files aren't getting corrupted... they are going through usb...
i think it has something to do with the phone...
Double check the compatability on the headset, if it plays fine through the USB headphones, and the headset sounds perfectly fine on another phone...
What version is the heatset? blue tooth 2 or whatever the newer version is? I know the phone supports it but something else might have changed? Just something to look into.
Aside from a firmware flash or some software bug I cant think of anything else If the compatability show's up that it should work might try calling HTC's support line?
i contacted blueant before purchase and they assured me the headset is compatible... also tmobile claims that its compatible as well... they even have tmobile packaed oem boxes for this particular headset... the hardware protocols also line up... technically, everything should work!!!
i already contacted htc with regards to this issue... this was their reply:
Thank you for your inquiry in regards to Bluetooth headset stereo issue.
Ben, I know how important it is for you to have the bluetooth headset working properly, Unfortunately there is no updates or patch available for the T-mobile wing to fix the issue, although T-mobile might have a ROM upgrade. The reason why the T-mobile dash had no issues with the headset is because it has different drivers for bluetooth support. Look into possibly upgrading the device rom to try and resolve the issue, otherwise you'll need to purchase another headset which is compatible with the device.
i looked into updating the rom and it appears that i have the newest version: 4.10.531.3 WWE from march 15th 07... i wasnt' able to find anything newer... does someone else know of a newer version for the hera110???
Hmm, might be something in T-Mobiles software that is nerfing your set... Not sure of what though...
So I have an xperia, and I have a new JVC Bluetooth deck, I was so impressed how flawlessly it worked with my old phone the Kaiser/tilt, but to my surprise I have not been able to get it to properly pair up with my newer xperia. They will read each other and try to connect but I always end up getting an error. Sometimes it still shows up as connected but nothing works. I used my kaiser/tilt for both calls and streaming music through my new JVC bluetooth deck and I loved it, so its pretty dissapointing when I upgrade to what is/was one of the hottest & expensive windows mobile phones and it apparently has bluetooth issues.
I tried a few fixes already like changing the registry to read as a normal phone and I added in a missing bt profile, unfortunately nothings changed. I am curious tho because i had a magician and they had whole bt stacks that I messed around with, and I'm also wondering if a flash or two of a new rom may make a difference. Ocerall I'm really happy with the X1 (unlike my tilt/kaiser which had lots of problems) so much so that I don't really feel the need to flash a new rom, but if it might have a chance of fixing my bt I'm all for it.
Let me know if anyone has any suggestions, tia.
Hey Guys,
after weeks of trying and searching, i'm really considering to sell my Galaxy. But before i do so, i want to ask once more on this way, if anyone knows or at least got a clue about how to fix the bitpool/bitrate quality for bluetooth stereo streaming. It's important to me as i use my phone for music a lot.
The problem is known for some people, but not a lot coder/tweaker tried their luck on this yet.
The only way I know would be to flash cyanogen. I even tried it, but cyanogen is not for everyday use on the galaxy yet imo. It still has a lot more other bugs, and the battery life is much worse compared to my stock 2.3.3 rom.
Perfect solution for me would be a rom based on the stock gingerbread, with just the bitpool issue fixed. I'd even donate anyone who could fix that.
So if someone knows more about it or would give it a go and tries to fix it... I'd really appreciate that as apart of this issue i really like my Galaxy S
Have you tried gb stock ? I am on jvh and think Bluetooth streaming has improved. Try it and see if you hear the same way?
Sent from my GT-I9000 using XDA App
Hey fylim, thanks for your reply
Are you sure about that? Currently i'm on stock gb. I think JVB... is JVH newer?
EDIT: I've checked it i'm on JVB and modem is JVK. But i haven't read about any improvement on JVH yet... well i may try JVH then... I'd do everything to get it fixed :/
Ok, ive tried JVH... still the same aweful quality Ok, seems like i'll get a WIN7 phone soon then :/
You've got to be kidding me. Just use fre*kin wired headphones. The SGS +voodoo is like one of the best DAPs in the world and you're going to sell it because you want more quality with your bluetooth headset. Let me tell you something bluetooth and sound quality shouldn't be used in one sentence.
There is a reason i bought a bluetooth stereo headset. And just a little headup: You may have terrabytes of space on your SGS to save FLAC's or Wave files, but i bet you're using compressed music as well... So you shouldn't even start to think about "quality" even with wired headphones. So its not a qualified comment at all...
Also, like i stated before, i tried cyanogen and the quality with the bluetooth headset is the same as with wired ones. Also on my mates W7 phone its decent (after a 1 minute tweak)...

Dude, sorry to spam in your thread but I got bothered by that "not a qualified comment". First ,as I said the SGS with voodoo just blows out of the water almost all DAPs (and I mean dedicated music players). Second, yeah I have a 32GB micro sdhd card which I use with my SGS and I almost exclusively listen my music in flac or in mp3 which I have personally ripped. And I'm an audiophile with a vast collection of headphones (even bluetooth ones) and I know what I'm saying - even cheap wired headphones with voodoo sound way better than any bluetooth ones. It's your choice, I understand that wireless is more comfortable but trading an awesome phone with awesome audio quality for a Windows phone which doesn't even have Angry birds for it, let alone proper multitasking and stuff is a bad deal
There isn't much room to talk about quality even if we have 320's mp3's... Trust me, i'm really strict and sensible with such sounds issues, thats why it bothers me so much with the small bitrate on stock gingerbread. It sounds like 96 kbps compressed streaming. With cyanogen it seems to stream in the highest possible bitrate which is about 328 kbp's as far as i know (at least thats how fast it streams to the bluetooth devie on my pc). However, whats the difference between a 320 being played without bluetooth and with bluetooth? I can understand your argument if its a non compressed file format. But even Voodoo doesnt do magic with it. I got quite a bunch of cheap and expensive earplugs which i tested with, and without the bluetooth device. Trust me, you wont hear any differnce (on cyanogen at least)...
But anyway, i just tried the newest cyanogen build and some stuff got improved especially battery seems to be somewhat better... so maybe there's light at the end of the tunnel and i'll wait how cyan gets improved. I'll stick with my SGS then, as i know its sound is really good otherwise and also the rest
If i plug-in an other headset than the original X1 headset it echoes and I don't hear anything on my right side. Has someone got a solution? Or do i have to buy another one? reaction A.S.A.P. please
Is there not any software that can change bass etc. for X1?
lemme think...
easiest way is flashing a custom-rom with htc sense 2.5, it comes with an app called "audio booster" which gives you an equalizer w/ presets. most of these roms also have modded audio drivers cooked in for better sound (at least of ultrashot's dynamics i know for sure).
then there were quite some apps for win mobile, but they're are all very old by now. if you don't want to flash a sense-rom, you could search for "srs wow hd". another audio-driver, but iirc there were always problems with it...

I've had WOW HD buy now and did not work. I already have a 826x ROM. Audio booster also tried and it didn't do much. I just want to be clear about the problem, its about that i o not have the original headset of the X1 wich you get in the pack if you buy the phone, i have a completely different headset. On the right side of the headset i don't hear anything and in the other only a echo with kggg sounds.
You can use any headset you want. Rather sounds like yours is crap/broken. ^^ or hw-failure on x1. Have you tried others?
Not something you fix with installation of software.

when i had the original one it didn't screw the music up, only with other headsets.
I tried multiple music formations and that also in screwed up sound...

Can it we a hardware problem? If so thn the original wouldn't work either, right?
Don't be afraid to give answers people, thanks.
yeah well, if stock is working, then it's not on the phone.
how's your headset, does it work on another device? have you really tried different headsets or just the one?
stock-headset isn't specially recognized as "original SE".

I am not using an SE headset, but the headset works on other devices pretty wel.
But I think to see another problem, when playing a song, the audio is the same as on the headset. Maybe there is a problem in the audio files? (although it sounds a little weird)
