I went to town and did just that. I ended up buying a Typhoon bluetooth 
usb adapter (http://www.typhoon.de/de/art.php?p=838&pv=3). I had the 
clerk check out the webpage for me and there we found "Functions: Main 
chip - CSR BlueCore ". That's why I bought it and didn't check out th 
other available devices (only one).

Today I tried to get it to work...

I already applied the MTU patch.

Maybe they changed the internals of the device in the revision I bought...


Setting volume and connection does work just fine, but no sound only 
some white noise. Now I can try to bring it back (might be difficult 
since the package is opened) or try to get it to work. I've looked 
through the archives and it doesn't look too good. Are there any news on 
this?


There is a pecularity I'd like to understand: When I use alsamixer to 
set the sound level, there are four settings: Master, Mic, AGC, 
Loopback. I can modify the first two, btu the other ones are disabled. 
What are they? Are they related to the problem?

When I use aplay to try to play a sound, it hangs after writing out the 
version info. Strace gives:

And there it sits doing nothing.
