I don't know if there is a method a enable Mix, probably not, because
it depend on hw. Anyway with new alsa drivers, i suggest you to use
the latest one, wsa introduced aloop virtual device, which is usefull
to record what you are playing. Here it is a configuration:
#
# Split 4 channels stream to play them to 2 soundcards:
#
# in: LRLR out: LR -> through main sound card (with dmix)
# LR -> through aloop sound card (with dmix)
#
pcm.multi {
type multi
slaves.a.pcm "dmix:0,0" # main sound card
slaves.a.channels 2
slaves.b.pcm "dmix:1,0" # aloop sound card
slaves.b.channels 2
bindings.0.slave a
bindings.0.channel 0
bindings.1.slave a
bindings.1.channel 1
bindings.2.slave b
bindings.2.channel 0
bindings.3.slave b
bindings.3.channel 1
}
#
# Create a 4 channels stream from a normal stereo one
#
# in: LR capture out: LRLR
#
pcm.hdaloop_out {
type route
slave.pcm "multi"
slave.channels 4
ttable.0.0 1
ttable.1.1 1
ttable.0.2 1
ttable.1.3 1
}
#
# default PCM able to play through main sound card and record from
capture device
#
pcm.!default {
type asym
playback.pcm {
type plug
slave.pcm "hdaloop_out"
}
capture.pcm {
type plug
slave.pcm "dsnoop:0,0"
}
}
#
# PCM able to record from capture device and default PCM out
#
pcm.ear {
type plug
slave.pcm "dsnoop:1,1"
}
