Congratulations to Phil Wild on solving his audio over HDMI.  I took
some notes and here is what I have:
---------------------------------------------------------------------------------------------------
For HDMI cards run aplay -l and look for an output like this:

  Subdevices: 1/1
  Subdevice #0: subdevice #0
card 0: NVidia [HDA NVidia], device 3: NVIDIA HDMI [NVIDIA HDMI]

For this case, the key is card o device 3.

Setup for Myth:

Audio output device: ALSA:hw:0,3
Passthrough output device: ALSA:hw:0,3
Max Audio Channels: Stereo
Upmix: Passive
Enabale AC3 to SPDIF passthrough checked
Enable DTS to SPDIF passthrough checked
Aggressive sound card buffering off
Use internal volume controls off


For mythmusic:
Utilities/Setup -> Setup -> Media Settings -> Music Settings ->
General Settings
and then set Audio device to ALSA:plughw:0,3


asound.conf may be deleted for myth or changed as below:


asound.conf:

pcm.!default {
        type hw
        card 0
        device 3
}
