Hi,
I''ve been trying to get audio output from multiple cards working but
have not had much luck.
What I would like to happen is for 2 channel stereo audio to work over
the HDMI connector (to TV) and 5.1 channel DD and/or DTS to work over
the optical output (to receiver) simultaneously.
Below is my current .asoundrc file. It is the closest I've come to
getting the required outputs to work. Usually I get only one of the
outputs working.
pcm.hdmi {
type hw
card 3
device 3
}
pcm.optical {
type hw
card 0
device 1
}
pcm.multi {
type multi
slaves.a.pcm "hdmi"
slaves.a.channels 2
slaves.b.pcm "optical"
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
}
The outputs of aplay -l and aplay -L follow:
pvr@orion:~$ aplay -l

Can anyone help me get this working correctly? Any hints would be
greatly appreciated.
Thanks,
