I use the same module and this is my ~/.asoundrc (same as the howtos on
alsa-project.org[1]):
-----8<---------
pcm.!default {
type plug
slave.pcm "dmixer"
}
pcm.dsp0 {
type plug
slave.pcm "dmixer"
}
pcm.dmixer {
type dmix
ipc_key 321456
ipc_key_add_uid true
slave {
pcm "hw:0,0"
period_time 0
period_size 1024
buffer_size 4096
rate 48000
}
bindings {
0 0
1 1
}
}
ctl.dmixer {
type hw
card 0
}
-----8<---------
for mplayer I simply use this ~/.mplayer/config:
-----8<---------
vo=xv
ao=alsa1x:default
#stop_xscreensaver=1
cat: ~./mplayer/config: No such file or directory
-----8<---------
while xmms is already configured to use alsa default pcm
the pcm.dsp0 allows using dmix also through oss emulation so mpg123 is
happy too. Note: I have no sound server installed and dmix is working
great :)
