Hi,
i'm using an asus mainboard with a via 8237 sound chip and coaxial
s/pdif out.
I'm trying to get the s/pdif working with oss-emulation and dmix. It
works great and i'm absolutely satisfied with the setup except that the
sound stops sometimes without any obvious reason. Sometimes it then goes
on after a while, sometimes i have to restart the computer. I don't know
if it is a problem with alsa, but maybe someone knows what's going
wrong. Perhaps i'm using wrong values in the slave section in
pcm.dmixer; i have copied them from another .asoundrc at the alsa homepage.
Another thing is, that i have /dev/dsp, but programs using this device
like audacity (or cat /dev/urandom > /dev/dsp) are mute.
Mixer levels are all about 75%
Any ideas? Thanks in advance,
henrik
Here are my .asoundrc and modules.conf (gentoo /etc/modules.d/alsa):
pcm.!default {
type plug
slave.pcm "dmixer"
}
pcm.dmixer {
type dmix
ipc_key 1024 # must be unique!
ipc_perm 0660 # sound for everybody (at least in your group)
slave {
pcm "hw:0,0,3" # you cannot use a "plug" device here, darn.
rate 48000
period_time 0
period_size 1024 # must be power of 2
buffer_size 8192 # dito
}
}
pcm.dsp0 {
type plug
slave.pcm "dmixer"
}
ctl.mixer0 {
type hw
card 0
}
