I don't know how long it's been since I popped my head in this thread, but I thought I'd just mention the status of a2dp on my own tablet, currently:
As johnx mentioned before, after flashing to Diablo, there were some weird issues getting a2dp working, but I believe repairing my headphones and rebooting is what actually solved it.
I can currently play not only audio, but also video with mplayer flawlessly, encoded at very high quality. Here is an example of a video file that plays very nicely: http://www.ageofikon.info/N10-Haruhi.avi (Melancholy of Haruhi Suzumia AMV).
Just thought I would let everyone know, in case there is any question of how well you should be expecting a2dp to work.
Note that as of this moment, I have gotten lardman's SBC DSP task to play audio very well, but I still have to use the software encoder for video to work well (it basically just freezes the video stream and the audio stream is very choppy using the 1.0 release of the DSP task). Hopefully when he releases the new version this will be improved. Gogo lardman, you are my hero!

New version is released and on the Garage page, please let me know how it works when you decouple the DSP & ARM speeds (see instructions in the Release Notes) to let the ARM run at 400MHz while encoding the audio on the DSP (at 133MHz).

That's a Bluetooth error as opposed to something wrong with the DSP task.
I've seen that before, try repairing your headset, with some reboots thrown in for fun (I know, not very scientific, but I'm not a Bluez expert.)

In fact everytime i try to follow those steps my mplayer just plays any video in fast forward mode without any sound. I have to reflash to get the normal mplayer back.
Is it possible that you have another mp3 player, computer or cell phone that is also paired to the headphones and might be keeping a connection open?
This is what it gave me in the terminal when it happened (it is exactly the same error you got in your last post):

Install it and see how it goes. Note that this is for Diablo only. Also check the install_sbcenc.sh file to check that it works correctly.
Please give feedback at the Garage project.
Enjoy,

I tried to install this downloaded the 4 files to user/MyDocs,
ran the deb in application manager
un tared the .gz file to /lib/dsp/modules
~/mydocs/chmod 777 ./install_sndcenc.sh
~/mydocs/./install_sndcenc.sh
it said everything installed "now please reboot" i reboot and now it just keeps rebooting, get about 75% on the boot loader graphic and reboots, any help?
Thanks for your work on the a2dp support, so far i love it!

oh dear, I think that might be my fault.
The script will add the dsp task to the dsp_dld_avs.conf file no matter what (like even if it's already been added), this might cause issues.
You should be able to disable the lifeguard reset with the flasher, boot, remove the extra line in said file, then reboot and all should be ok. My apologies

I've added a note to the release notes, I should also tweak the install script. Someone kick me on IRC tomorrow to remind me to do so!
Sorry for the hassle anyone who's been affected
