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
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.
