[alsa-devel] Problem with bluetooth headset and "aplay -l"
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.

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.
