Disclaimer: I haven't ever done this :/
All my below knowledge actually comes from getting PulseAudio to route to
anything BUT the HDMI that it uselessly decided to default to ;)
To get PulseAudio to route the audio out HDMI you need to run Pulse Audio
Volume Control (pavucontrol), and check:
1) In the configuration tab, check that the HDMI device is enabled and set to
an appropriate profile (since you are using an nVidia graphics card this
should show up as a separate device to your normal sound card).
2) In the playback tab, that the stream from MythTV is being routed to the HDMI
device (you may first need to get MythTV to start playing something for it
to appear in this tab).
3) There are also settings in the output devices tab that may be relevant.
I don't know whether this will solve your problem, since you note that
ALSA:hdmi doesn't work, and AFAIK PulseAudio will route to that.
Also, Appendix I in the nVidia driver documentation points to this document
which has a lot of troubleshooting info, known bugs, etc:
On the day *I* go to work for Microsoft, faint oinking sounds will be
heard from far overhead, the moon will not merely turn blue but
develop polkadots, and hell will freeze over so solid the brimstone
will go superconductive.
