I use to talk on this on my speeches, you just lack an asym pcm with
can join the microphone with the dmixed output. This conf also adds
dsnoop so varios aplications can read data from the same microphone at
the same time :)
#The default device:
pcm.!default {
type plug
slave.pcm "asymed"
}
#This is the audio output:
pcm.dmixer {
type dmix
ipc_key 1024
slave {
pcm "hw:0,0"
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:0,0"
}
#This makes both channels work together.
pcm.asymed {
type asym
playback.pcm "dmixer"
capture.pcm "dsnooped"
}
