[GnomeMeeting-list] Select custom alsa pcm device?

[Gilles Schintgen <gilles vonet lu>]

Hi,

I'd like to know if it's possible to choose a custom alsa pcm device. The GUI 
only offers "default" and "VIA 8237". However, I'd like to choose the 
"headset" pcm device which I've defined in my .asoundrc.

I'm using a simple headset with two stereo connectors. The headphone jack is 
plugged in the rear channel of my 5.1 onboard sound device. Since I'd like to 
use the front and rear channel independently I had to resort to 
this .asoundrc:

pcm.rearx {
        type route
        slave.pcm "surround40"
        ttable.0.0 0
        ttable.1.1 0
        ttable.0.2 1
        ttable.1.3 1
}
pcm.!rear {
        type plug
        slave.pcm "rearx"
        slave.channels 4
        ttable.0.0 1
        ttable.1.1 1
}
ctl.rear {
        type hw
        card 0
}
pcm.headset {
        type asym
        playback.pcm "rear"
        capture.pcm "hw:0"
}

As far as I can tell everything works as expected, i.e. the "headset" pcm 
device is completely independent of normal sound playback (e.g. sound 
notifications, music, etc.). The only problem is that I can't find an option 
in ekiga to use this device.

Would it be difficult, from a technical point of view, to implement support 
for these "virtual" pcm devices? Or is there already a hidden option in a 
configuration file somewhere?

Thanks,

Gilles
