Try this one:
pcm.!default {
type plug
slave {
pcm "both"
}
}
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 "analog"
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 1
*device 3*
channels 2
}
pcm.analog {
type hw
card 0
device 0
channels 2
}
I'm not sure exactly which device is the HDMI so if it is not working
replace the bold out "device 3" with "device 9" and then "device 8" and
"device 7" in the consequent retries. use ALSA:default as device in MythTV.
