Wow, my reply had some strange formatting, sorry.  Here it is again.


Andrew,

Here are my notes from what worked for Phil.  You have a very modern
sound card.  I doubt it is the problem.

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.

This setup has worked:

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


Optional for myth but perhaps a good or bad thing:

asound.conf:
- Hide quoted text -

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