You didn't say what happens when you go from the myth box to the
Yamaha directly or if you did I missed it. I just want to make sure
you are talking about the same setup in both myth and windows.
I had a similar problem with my spdif setup that was solved by
reversing the bits in the audio bits with this setting in asound.conf
pcm.!default {
type plug
slave {
pcm "hw:0,1"
format S32_LE
}
}
Obviously yours would be different because your hdmi device is
unlikely to be "hw:0,1" but you might try adding the format line.
Without the format line, only one of my two decoders worked.
