Hi
I have a wired problem. I can pair, and connect a bluetooth headset using bluez-simple-agent and bluez-test-audio, no problem.
I kan also record and play using aplay/arecord -D bluetooth.
But i can list the device in "aplay -l" og "aplay -L".
My gees is that I am missing a ctl interface or a kernel module. (or that ubuntu has done something nasty)
My system is a ubuntu 11.04, where the bluetooth pulseaudion plugin have been removed. I am developing for a embedded arm platform also running ubunut 11.04 and the problem is the same on target.
The list of modules is listed in the bottom og this email.

I am so sorry!
I have made a spell error, but a rather important one.
The line
- But i can list the device in "aplay -l" og "aplay -L".
should have been,
But i can't list the device in "aplay -l" og "aplay -L".
The big problem is that i am looking for the ctl interface. When the device is not listed using aplay -l og -L I have a problem.
Regards Anders Gnistrup

Bluetooth is wireless. :o)

"aplay -l" lists kernel drivers, while "aplay -L" list devices for which
there is a name hint entry in the alsa-lib configuration files.
The bluetooth audio driver itself is not a kernel driver (it's a user
space plugin), and, apparently, its configuration file does not define
name hints.

Clemens
