      hi!
this does not work for me. xmms and rhythmbox play fine, but gaim sound
does not and gaim crashes when i try to close it.
i am not a programmer  but i test whatever you tell me :-)
would be great if i could be helpful here...
regards,
christian

I have further suggestions: make the defult output device dmix, and
default input device dsnoop. Then create a default device with full
duplex, like this:
#
# DMIX input device
#
pcm.!output {
    type dmix
    ipc_key 1234
    slave {
        pcm "hw:0,0"
        period_time 0
        period_size 1024
        rate 44100
    }
}
#
# DSNOOP output device
#
pcm.!input {
    type dsnoop
    ipc_key 1234
    slave {
        pcm "hw:0,0"
        period_time 0
        period_size 1024
        rate 44100
    }
}
#
# ASYM duplex device
#
pcm.!duplex {
    type asym
    playback.pcm "output"
    capture.pcm "input"
}
#
# Make the duplex device default
#
pcm.!default {
    type plug
    slave.pcm "duplex"
}
#
# OSS Compability
#
pcm.!dsp0 {
    type plug
    slave.pcm "duplex"
}
ctl.!mixer0 {
    type hw
    card 0
}
This should enable sound mixing - both input and ouput - to /just work/
for all supported cards.
