This version has been rock-solid for a couple of months now:
pcm.!default {
type plug
slave.pcm "asymed"
}
# This is the audio output:
pcm.dmixer {
type dmix
ipc_key 1024
slave {
pcm "hw:1,0"
period_time 0
period_size 1024
buffer_size 4096
rate 44100
}
bindings {
0 0
1 1
}
}
ctl.dmixer {
type hw
card 0
}
# This is the microphone
pcm.dsnooped {
ipc_key 1027
type dsnoop
slave.pcm "hw:1,0"
}
# This makes both channels work together.
pcm.asymed {
type asym
playback.pcm "dmixer"
capture.pcm "dsnooped"
}
I am very happy now! Thanks for all your help!
Regards,
Phil.
