[Ekiga-list] simultaneous alsa access to sound card

[Sven Nielsen <post svennielsen de>]

hi,

after fiddling around a bit with alsa setup on my system (debian 
testing) I could not get ekiga to access sound output while another 
sound application is also running.

A few minutes ago I started up ffplay, mplayer, and amarok (using arts > 
alsa ), all playing simultaneously through alsa without problem, so I 
assume my sound card is capable of hardware mixing the sound streams 
(integrated AC97 Audio on nvidia2 controller board).

I have also tried setting up dmix configuration in /etc/alsa/asound.conf 
(and /etc/asound.conf, forgot which one was the right directory), as 
follows:

> cat /etc/alsa/asound.conf

pcm.dsp0 {
   type plug
   slave.pcm "dmix"
}

ctl.mixer0 {
   type hw
   card 0
}

So, why is it that ekiga reports:

"Could not open audio channel for audio transmission"

when a call comes in while I listen to some music?

I am running asterisk on my home server (with a hard phone connected 
over hfc-s isdn card), and I would really like to take calls at my 
desktop PC so I won´t have to walk over to my other phone anymore.

Any help appreciated,

Thanks,
Sven Nielsen
