A2DP/AVRCP in Crossbow

[Daelyn]

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!!

Following the development/information on MS BT Stack change to Widcomm BT Stack on following links

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.

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.

Thanks Taz!

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