Kevin,
In my case it was a matter of setting pulse audio to use the correct
alsa channel. I don't have access to the machine right now but from
memory and using examples from the computer i am on,
on my machine now, doing `aplay -l` gives:
card 0: Intel [HDA Intel], device 0: AD198x Analog [AD198x Analog]
Subdevices: 1/1
Subdevice #0: subdevice #0
card 0: Intel [HDA Intel], device 1: AD198x Digital [AD198x Digital]
Subdevices: 1/1
Subdevice #0: subdevice #0
on my nvidia machine there were two cards, the headphone jack and the
hdmi port. The hdmi was card card 1. Card 1 had i think 4 devices named
(think) 1,7,8,9.
You can make pulseaudio use the other card by
echo "set-default-sink 1" >> /etc/pulse/default.pa
that will select the default device (above, card has multiple devices)
though which is number 1, for me and others i saw the correct was 7. You
can test it with:
aplay -D hw1:7 test.wav
also hw1:1 -> hdmi1:0, hw1:7 -> hdmi1:1 etc, so
aplay -D hdmi1:1 test.wav
should be the same thing. To make it permanent in
/usr/share/pulseaudio/alsa-mixer/profile-sets/default.conf i had to change
[Mapping hdmi-stereo]
device-strings = hdmi:%f changes to hdmi:%f,1
There may be other ways to do it but i'm provisioning the system a lot
so i needed something i could script.
Hope it helps.

running an HDMI-connected screen, when 600 pixels vertical resolution

from the display (any screen), showing that maybe the drivers were not
all that up to date. But where do you fiddle around with the
sound-over-hdmi?
Thanks,

If you use the nvidia drivers (they need to be within about the
last year) you can put audio over HDMI though it requires a bit of
configuring.
