Yup i can confirm that that does what it's says on the tin, i still have a slight problem every now and then where mplayer and alsa get overrun but i think that might be just down to load spikes and the sco codec not being able to empty the buffer out

@ascherjim: Just setup your .asoundrc the way I have it in my instructions at the top of the thread. The "profile a2dp" line is technically optional. I included it because I had issues with a2dp not being available and my N800 automatically reverting to SCO (the mono sound, headset protocol). Tell us how it goes. The more data points out here the better.

Thanks you guys for the clarification. I did edit the file, but my trusty Bluetooth headphones so far don't work in either Kagu or Kilikali.
Hope I understood the second edit instruction correctly -- "lp rswitch,hold,sniff,park; and remove rswitch" to change the line to
"lp hold,sniff, park;"
And what should I have done with the "Setup the .asoundrc file" instruction, if anything?
As for not working. Do you have fmradio installed? If you do make sure you can use regular plugin headphones as there is a switch on it that forces sound to the speakers (just using the headphones as an antenna) that if it's set wrong you can't use regular phones either.

Interesting update: I got A2DP working on my old Zaurus C1000 (XScale @ 416MHz) with a USB bluetooth dongle. Plays back smoothly with ~15-20% CPU usage. Somehow there is definitely a software issue with A2DP on the N8x0 w/ 2008OS. I'll be doing further research. I wonder if it's mplayer, bluez or alsa though...
Edit: On the Zaurus it's also quite a bit more resilient while I'm loading down the machine with lots of other CPU intensive tasks and doesn't even skip when heavily swapping to the SD card.
Edit: I did a couple quick tests of mplayer playing to my bluetooth headphones on 3 machines (Zaurus, N800 and my desktop). The Zaurus and the Desktop were both using the same usb bluetooth 1.2 dongle since I only have one.
The buffersize on the N800 looks quite low, comparatively. And to top it off the frequent complaints about "broken pipe" and "trying to reset soundcard" seem to happen on the other platforms mostly under high load when the buffer would be most likely to be empty. I wonder if this might be connected to the other issues the mplayer guys are having with alsa...

I'll be watching this thread for further developments -- as well as awaiting the arrival in the mail of my ad20 mp3 dongle! Keep up with your dedicated endeavor on this matter. Regards, Jim

@ascherjim: So are you saying it does work in mplayer but not in the other players? I really have no idea on what other players may or may not work. All I can tell you is how to make it work with mplayer. The authors of the other players will have to answer questions about whether their software works with A2DP in 2008OS. If it doesn't work in mplayer, what error does it give? Also, be sure that you rebooted after making changes to anything under /etc/bluetooth/ . Tell me how it goes for you, and thanks for helping me test this.

Probably a very naive question.

Hope I understood the second edit instruction correctly -- "lp rswitch,hold,sniff,park; and remove rswitch" to change the line to
"lp hold,sniff, park;"
And what should I have done with the "Setup the .asoundrc file" instruction, if anything?
