Ported original thread from SF list:
  http://article.gmane.org/gmane.linux.bluez.devel/16060

I can reproduce the exact same error with a BT250 hooked up via
a different bluetooth adapter to an amd64 machine this time (the
last one was i386), running 2.6.26.

Stuart Pook told me about bluez-utils 4.4 [0] - I am still using 3.36
[1], but the wiki page says that I need 3.16 or newer. Would
I have better luck with 4.4? Where does this stuff come in anyway?
I am running hcid in the background, but I know too little about
ALSA or Bluetooth to be able to see how the two interlink. The wiki
mentions a btaudiod, which 3.36 seems not to have. Is that needed?
