Yes, yes you are thinking gee why didn't he do a search but I have. I have a Zotac ION 330HT board that is hooked up to my TV through HDMI and to my receiver through Optical.
What I want to do is the following:
Simultaneous sound through both HDMI and Optical BUT if anything is AC3 or DTS, it needs to be resampled to PCM to go over the HDMI. And anything PCM needs to be resampled to go the the Optical. Right now it seems like the all passthrough only goes through the Optical and anything PCM will go to the HDMI although navigation sounds will go across both.
Anyone done this?
Here is my asound.conf:
pcm.!default {
type plug
slave {
pcm "both"
}
}
# slave.pcm {
# type hw
# card 0
# device 3
# }
# }

pcm.both {
type route
slave {
pcm multi
channels 4
}
ttable.0.0 1.0
ttable.1.1 1.0
ttable.0.2 1.0
ttable.1.3 1.0
}

pcm.multi {
type multi
slaves.a {
pcm "tv"
channels 2
}
slaves.b {
pcm "receiver"
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
}

pcm.tv {
type hw
card 0
device 3
channels 2
}

pcm.receiver {
type hw
card 0
device 1
channels 5
}
