I think, this story is really old, but I didn't get managed to it. I'm
running Debian unstable on my T40 and can use only one sound output a
time (eg. playing mp3s in XMMS but no sound for mozilla).
So, I was browsing the net and found the solution: asoundrc. I created
one, which looks like this:
*****************
pcm.amix {
type dmix
ipc_key 50557
slave {
pcm "hw:0,0"
period_time 0
period_size 1024
buffer_size 8192
}
bindings {
0 0
1 1
}
}
pcm.!default { # route ALSA software through pcm.amix
type plug
slave.pcm "amix"
}
pcm.dsp0 { # oss software as well
type plug
slave.pcm "amix"
}
ctl.mixer0 {
type hw
card 0
}
*****************
Unfortunately, same problem; no multi channel mixing (or however you
want to call it). Another curiosity is, that if I try to play two mp3's
with mplayer and alsa output, it only works for the first one. The
second mplayer waits for the device to become free. I thought, that this
should work for ALSA?
Maybe someone of you guys can point me to the right direction. I'll also
post my loaded modules here:
