A2DP with Official WM6 Roms

[leewilko]

I have asked this question in several other threads and have not recieved a response. I have also searched all threads within 1 week history for A2DP content and cant find my question answered anywhere... so here goes!!

Can people confirm their experiences with A2DP on the official Wm6 roms.

Does the skipping still occur with default rom settings?
Do you still have to install sleuths a2dp patch to get things anywhere near stable?
Is default sound quality good?
Is tweaking the bitpool and other reg settings still needed?

I have battled with all other roms and my Motorola Ht820 headset to get skip free good quality audio and never managed to get it working consitently and was waiting for the official WM6 roms to see if they would crack the issue?

All feedback appreciated.

I've had no problems with A2DP in the official Dopod WM6. it works great straight after install with no tweaks at all. It seems to be skip free and with good sound quality.

The only problem I still have (and had with every version & tweak) is playing m4a files with WMP. When playing these files, the phone goes back to the speaker...

Cool thanks for letting me know, is it working in official rom for anyone else without messing about with fixes?

Come on guys some of you must be using A2DP is it stable with out tweaks and fixes in the official rom?

I'm a big A2DP headset user when working out, so I have been keeping a close eye on the sound quality with the different WM6 ROM versions here. As posted before, the version from Sleuth was GREAT in sound quality.

The "official" WM6 ROM from HTC for Cingular/AT&T (US) does have the registry entry for UseJointStereo set to 1, so that is great. However, I did see that the MatBitRate and SampleRate were also there and set to 30. So, following the "best" settings on this forum, I deleted these two registry entries and added the increased rate entry of SampleRate at 48000.

The workout this morning sounded as sweet as with Sleuth's ROM.

Sounds promising, just gonna try my headset now with official dopod rom. Fingers crossed. What head set are you using?

[rgelfand]

I have a parrot hands free car kit and I find the quality is best when I just leave all settings as is. I think the a2dp on this rom sounds exceptionally weel.

I'm using the Motorola S9 headset.

I still have the skipping issue with Dopod SEA version and SE HBH-DS970. Before that I had one of LSVW's ROMs installed and AD2P used to work just fine in that rom.

[joej]

yup, the dopod release does not seem to have all the fixes done here. i have tried LSVW and black and no more skipping issue with my DS970.

Thanks for the feedback I am still getting skipping in the Official Dopod rom....Argggghhhhhhh !!!!!

Anyone know of any plans for a fix the A2DP issue ever??????

Did you apply Sleuth's patch? I wasn't sure if it would work on WM6 (official), but, thank goodness, it does! After 9 months I can listen to music!

Hi, Was hoping that the patch that sleuth did (to fix the looping code error) would have been incorporated by M$ into the release. Looks as if it has not, which is a real shame. Just about to flash Black Satin and will try with and without Sleuths patch and post the results. Thanks for all the feedback guys, much appreciated.

on a whim i knew what a2dp was but i just wanted to wiki it..
check out the LAST LINE...

Advanced Audio Distribution Profile (A2DP)
This profile defines how high quality audio (stereo or mono) can be streamed from one device to another over a Bluetooth connection[1] - for example, music streamed from a mobile phone to a wireless headset.

A2DP was initially used in conjunction with an intermediate Bluetooth transceiver that connects to a standard output audio jack, encodes the incoming audio to a Bluetooth-friendly format, and sends the signal wirelessly to Bluetooth headphones that decode and play the audio. However, many Bluetooth 1.1, 1.2, and 2.0 mobile phones and portable media players natively support A2DP, and most newer Bluetooth 2.0 headphones support it as well.[2] Bluetooth headphones, especially the more advanced models, often come with a microphone and support for the Audio/Video Remote Control (AVRCP), Headset (HSP) and Hands-Free (HFP) profiles.

A2DP[3] is designed to transfer a 2-channel stereo audio stream, like music from an MP3 player, to a headset or car radio. This profile relies on AVDTP and GAVDP. It includes mandatory support for low complexity Sub Band Codec (SBC) and supports optionally: MPEG-1,2 Audio, MPEG-2,4 AAC and ATRAC, and is extensible to support manufacturer-defined codecs. Most bluetooth stacks implement the SCMS-T copyright protection. In these cases it is not possible to connect the A2DP headphones for high quality audio. E.g. the Motorola HT820 can be used for high quality audio only with certain versions of the Toshiba bluetooth stack.

HOPE THIS HELPS!!!!

Offical SEA WM6 ROM fixed all my A2DP issues with my BlueAnt X5 headsets. (No tweaks at all required)

One problem remainds... it pauses/skips if Wifi is left enabled. Not sure if that is a software or a hardware issue (both protocols use the same frequency)

Hi, thanks for the article, but dont think this is the problem as I am now getting a lot better A2DP support, no problem with playing the audio or the quality just the skipping. Nothing really has changed, it is a bit more stable but needs sleuths A2DP patch to make it usable. My point is that is sleuth could fix this with a bit of code at home (no offence sleuth) then could M4 not have used the might of their developmental skillset to fix this most annoying problem.

I have been running the newest WM6 v3 rom from VP3G:

And I've been using A2DP without any skipping. I've been using an iTech clip headphone and it works great.

Same for me. With v3 of this ROM from VP3G, I get crystal clear STEREO sound thru my Motorola S9 headset.

1. Yes, I still got skipping after installing vp3G's v3.61 ROM.
2. So, yes, I installed Sleuth's A2DP patch.
3. That is all I did, and the sound is pretty good on my Motorola S805.
4. I haven't dome any registry tweaks, though I may to see if it makes any difference in sound quality.
