I'm one step further. I got the "Device or resource busy" error
because I use the wrong slave.pcm in my .asoundrc:
pcm.ice1712 {
type hw
card 0
device 0
}
# envy24 channel 1 only
pcm.channel1 {
type plug
ttable.0.0 1
slave.pcm ice1712
}
The first definition is not necessary because there is already a
default configuration in /usr/share/alsa/cards/ICE1724.conf with
dsnoop
# default with dmix & dsnoop
ICE1724.pcm.default {
@args [ CARD ]
@args.CARD {
type string
}
type asym
playback.pcm {
type plug
slave.pcm {
@func concat
strings [ "dmix:" $CARD ",FORMAT=S32_LE" ]
}
}
capture.pcm {
type plug
slave.pcm {
@func concat
strings [ "dsnoop:" $CARD ",FORMAT=S32_LE" ]
}
}
}
Now I changed my .asoundrc to
# envy24 channel 1 only
pcm.mono_channel1 {
type plug
ttable.0.0 1
slave.pcm "default:0"
}
# envy24 channel 2 only
pcm.mono_channel2 {
type plug
ttable.0.1 1
slave.pcm "default:0"
}
and so on.
But I still cannot record channels beside the first one. On the rest I
a recording with no sound.
Am I using the right ttable definitions?
Thanks,
Peter
