A2DP/AVRCP in Crossbow

Hello there.
I'm a newbie to using A2DP/AVRCP, sorry about that, but I have big issues.
I have huge lag when trying it out.
Specs:
HTC Universal
Midget's WM6 (Crossbow)
Radio 1.14
Bootloader 1.01?
Sony DR-BT20NX (really nice ones).
Anyways. I pair it up, no problemo at all. Tried a few calls. Works fine. Selected both handsfree and wireless stereo from profiles ofcourse.
So, I tried playing a movie in TCPMP. Audio and Video stutters every second. Tried playing a MP3 file in Media Player. Audio lag every second.
DAMN!
So, I went in to all these threads about A2DP/AVRCP in the forum (read them before) and checked out fixes etc. Everything seems to already be applied in this ROM. Priority256 value exists (in another folder though as described for another device, HKLM/BuiltIn/Drivers/WavDev I think)
What the heck can I do? I'm not comfortable applying different patches because I think A2DP support in every manner is already applied, so as the registry values.
HELP ME!!

Any one know more?

Just a thought. Is it possible to deactivate SBC (recoding/decoding) of MP3's?? My Sonys support direct MP3 streaming.

Tried out BT Stack change for Hermes patch/program.
TEST RESULTS ON UNIVERSAL WITH WM6 (Midget aka Helmi unreleased)
Sound IS great. But other than that, this program does not work very well on my device. Of course this is designed for Hermes but I gave it a shot.
Issues:
1:
Screen flickers (only when this BT is turned on).
Flickers really bad and unable to use device.
Fix: set the device to standby (power button) and wake it up again. Flickering gone
2:
Once BT is deactivated for a few minutes I can't start it again.
Fix: No fix found yet. Only a Soft-reset and directly activate BT works.
3:
I can't use my GSM/UMTS connection anymore. Trying endlessly. Even after soft-reset's I can't connect. WiFi works fine though.
Fix: No fix found yet.
4:
Unable to uninstall this program. Tried several times. I get to the "Soft Reset Device Yes/Cancel". I soft reset, program still there and working.
5:
Hard-Reset, complete setup with WAP, MMS, MAIL etc.
Installed Widcomm BT Stack again.
Soft-reset:
Screen flickering (fix)
No 3G/UMTS connection avalible anymore. Even when BT stack is completly shut down.
We need a specific one for our Universal. Who's up to fixing this for us?
KEEPING this post updated.
EDIT 06: 18:40 @ 21/01/07

ANYONE into programming/developing interested in taking this as a sideproject so all of us Universal users can benefit from this great software?
PS. No, Nuclear (aka Infidel)! Pleace do not participate in other than testing. And if you do, please don't be too exited and write lies/bs in this thread. Thank you. Ta ta

I'm currently using Midget's WM6 with a set of Motorola HT820 bluetooth headphones without any problems.
In fact I've tried a couple of WM6 roms now and both have had working a2dp & avrcp and if anything quality is as good as the AKU3.3 I was previously running.
AVRCP & connecting up seems to be a little more reliable than the last rom as that would occasionally lose the pause control, something I don't think has happened on WM6 yet.
It might be worth trying your device with a different set of bt headphones to see if the problem persists.

Hmm. Headphones shouldn't matter, should it?? It's one thing if the sound in my headphones is bad, but it is the DEVICE that has problems actually outputting to the recoder fast enough. It works fine with the Widcomm!!

Did you need to do any extra tweaking on Midgets ROM to get them to work properly?

i've hs-12W. I'm using it with midget's first vanilla crosbbow rom without any problems. without any tweaking.

I have tried the broadcomm stack on WM6 but couldn't get my jabra bt620s stereo phones to connect to both the headset AND stereo profile at the same time - if I connected it to the stereo profile, then it sounded great, with no log, but wouldn't act as a headset. If I connect it as a headset, it works fine, but all audio is mono, even stuff that shouldn't be. Should I be able to get this working for both at the same time?

Worked straight away without needing any tweaking.
Both stereo & phone headset work okay.
Also had Stereo configured with Universal and Phone paired with a hermes since getting a second data SIM and that setup is working okay as well.

Is it true that this headset can store two pairing profiles (ie I can have them paired with my Qtek and my PC)?

Bluetooth Stereo Headset Problem

Hi all
As this is my first post I just want to say a big thankyou for all the contributers to this site, awesome information and keep up the good work.
I have been running Black Majik on my M3100 for a week or so now and have been really impressed. the only slightly annoying problem I have is with my BT Stereo headset (HTC BH S100) which I have had only a couple of days.
Listening to music and controlling the media player(s) (Audio Manager and WMP) is fine, the problem I get is answering/initiating calls from the headset. After a reboot of the phone, the headset works OK for both music and calls, but after turning the headset off/on, the call handling functions don't work although wireless stereo does - its as though the phone loses the headset profile but not wireless stero. Stopping/Starting the BT stack from comm manger seems to reinstate the headset functions but this is frustrating!
I have searched multiple forums but have not found anything of use yet!!
Does anyone have any ideas
Thanks in advance
M.

same problem

please help us

Up ... Same WM6 version, same problem ... with a Nokia BT Headset, and a Sony Ericsson too ...
Thank you.

guess i have a worse problem then. cant hear my phone ring from my BT HS. not that ive tried to figure it out. i can live without listening to music. but it would be interesting to know how everyone is able to hear their phone ring from their headsets. im thinking its because of my headset. i have a moto hs810. does anybody concur?

I have the same problem and I've tried a P3600 and kaiser and the same problem.
As merlynuk wrote the problem seem that the HD lose a free hand function of it profile and only a reset and sometime a pairng od device solve it.
It's for me important to use this function in car or call a voice command but the MTB button seem not work.
bought this HD because belived it would be perfect with a HTC PDA but it's not really.
Do you have some suggestion ?
Do you believe it's better to sell this HD and to buy another ?
Someone know a HD device thet work perfectly as free hand and function as a call, a start a vocal command etc etc work fine ?
Regards
aladino

got the same problem: bought the HTC BH S100 after my touch cruise cause I thought to have no problem with vocal commands, but it doesn't work. music, player control, phone and pairing are perfect but no vocal dialling..
how can we solve this??

A2DP Audio routing problems

Well, being that this is my first post, I would first like to say that this site and forums are top notch, I have had my 8525 for about a month now and have learned an immense amount of knowledge in a short amount of time thanks to you guys. Now for my problem...
I have my 8525 running Black Magik, radio 1.43.00 and have recently purchased a pair of Sony DR-BT21G A2DP stereo headphones. Now I was a bit weary about buying these since I have seen no mention of them on these forums... buy anyways. When I first paired the devices together I was able to listen to music without problem, though sound needed to be tweaked. After trolling for quite some time through the forums (yes, the search feature works great) I found what appeared to be the best A2DP setting for audio quality, and now after playing with every possibility cannot get music routed to the headset, phone calls work without a hitch. I have downloaded BTAudio to route all system sounds to the headset but It doesn't seem to work. I toggle BTAudio on and I can hear slight static through the phones but the audio still comes out through the system speaker. I have played with A2DP settings in both pimp my black and HTweakC but have not had any success. I am planning on reflashing Majik tonight to attempt to set it up from scratch, but I was wondering if anyone here could shed some light on this issue? Thanks in advance.

Delete the pairing. SR. Re-pair. Should do hte trick. Better yet - for the most stable ROM and A2DP tweaked for the best sound "out of the box" - reflash with Sleuth255 variant of LVSW ROM.

How exactly can I delete the pair? I can repair the device but have not seen an option to remove it?

To toggle Audio to A2DP you might want to see:

There's a description and a link to download the CAB for A2DPToggle plugin too.
Let me know how it works on your hardware.

Problem with bluetooth A2DP headset

when I connected my JABRA BT620S with my spv m700 and started to play music with windows media player or other mp3 player, at first it worked well, while when I start to move(riding bike),in about 10 minutes, there always breaks happened. the voice firstly got lost, then appeared, then lost again... the gap happened about every 5 seconds.I've tried all versions radio, 3 different ROMs, seemed none of which can solved this problem. Can anyone plz help & give me a tip? Thx!

Try this fix. It gives the A2DP higher priority on the CPU, so that is continuously plays the sound:
http://forum.xda-developers.com/showthread.php?t=284974
However, it is known that A2DP AND Video at the same time is too much for the CPU of P3600. You may experience stuttering.

THANKS. I didn't run A2DP & VIDEO at the same time. Just want A2DP to work when riding bike. Hopefully this works.

A2DP Fix, I am challenged, did it work?

A related question:
It seems like bluetooth encrypts my audio files on my memory card. After a while i am unable to listen to them. But other files on the memory card remains fine. Has anyone experience this problem?

No, I guess there is something wrong with your memory card.
Are these WMA files with DRM?

Bluetooth headset disconnection...

Hello,
I tried many kind of WM6 and 6.1 ROMs and faced the same problem with different frequency rate: my bluetooth headsets disconnect very often (also during phone calls) and actually I don't have any idea what should be the problem.
The HW I have is: H200 with Logitech BT mobile pro and Plantronics voyager 510 (of course not together the latters).
I tried different radio versions and different roms: the only variance is the "well-work" period. If it lose the connection I have to set off/on the BT in connection manager. Does anybody have this problem or know the root cause/soution to fix? I really appreciate any kind of help/suggessions.
Thanks

I have the same problem as you... I tried WM5 and WM6 (Official Spanish ROMs) and no solution found. My hardware is H200 and Parrot CK3000Evo. I think may be a hardware problem. Any help please???

Don't think there's any easy answer. Often seems to be a combination of headset firmware and BT settings in your WM device.
There are good discussions of some of the problems and issues in this thread and this thread.
Other than that, you could try different firmware versions for your headsets - that solved my problem with a Jabra 8010 (till it just crapped out completely).
Alternate solution is to cut the crappy earphones off your standard USB headphone and solder on a 3.5mm stereo plug. I haven't quite got to that stage yet, but have come perilously close many times.

Do you think it refer to the A2DP problem? I don't want to use my HS to listen to music; otherwise these aren't A2DP compliant neither. I just want to use for phonecalls as it designed for.

I want to use for phonecalls too. I'm sure there is a bluetooth problem, perhaps a hardware problem. I have same problems using BT GPS...

I have the same issue with my Cardo headset and my BTGPS unit.
On a call and the headset cuts out and call diverts to handset.
BTGPS working fine then suddenly no connection to BTGPS.
Are any of you using MS Voice Command with BT Fix? My problems seem to have started right around the time I began using it. Before that I don't recall having any headset drops. Can not say the same about GPS as I've only had it a short time and have not un installed VC to test.
BTW. I'm using the stock WM6 update and radio for AT&T 8525 H100 hardware.

I'm not using voice command, and i probe it using clean official WM5 and WM6 ROM. Today I installed schaps WM6 ROM, but i have the same problem.

I have the same problem too. It will be ok for a few days, then wont be able to use BT (Plant 250). Then either I have reset the phone or turn off BT in phone and turn it back on, then it will work.
I believe it is a hardware issue, cuz I had a 8525 before, and never had this issue. But with the set I got now, its been a problem from day one.

I don't use voicecommand at all. The strange thing is that I use a Nokia BT GPS and it works fine always: no disconnection on long trips neither.

Do you use headset and BT GPS at same time? When headset disconnects BT GPS still working?

Yes, the HS is dropping but the GPS still working forward. Strange, but because of that I think it's not HW problem.

Sorry if I mislead you with the A2DP stuff. Didn't realise you were having issues with just the basic audio.
As I mentioned in the other post, though, there seems to be compatibility issues between the MS BT stack and some headsets. Changing ROMs probably won't help, because they still all use the same BT stack. Better to try playing round with the headset - see if you can change firmware in that, if possible.
I know there are some people trying to port the Widcomm BT stack to WM6, but I haven't heard of any real success yet.
