refers to: All of them should be unmuted. Press 'm' to unmute, and the right and left arrows to navigate. Then select 'HDA NVidia NVIDIA HDMI (ALSA)' as output for all items in 'Sound Prefrences' and select 'HDA NVidia (Alsa mixer)' as the mixer.
whats 'Sound Prefrences'?
heres the results of aplay -l

help... hdmi still not working... alsamixer shows "Nvidia GPU 0b HDMI/DP", but not as default i have to hit F6 to see that card and everything is unmuted... Ive installed the lastest nvidia drivers.
Shouldnt alsamixer show HDA NVidia first instead of HDA Intel?

I can't get HDMI audio working on MD either. My MD has an ION 2. My aplay output looks similar to yours. My alsamixer says nothing us muted, but the volume is at 0. I can't turn it up - it just refuses to budge from 0.
The wiki instructions you mentioned don't make any sense, at all. I bet the person that wrote them was using a GUI, but neglected to mention it in the wiki article.
All I can think of to try next is to update the nvidia drivers.

FYI: Got hdmi working by doing this (after trying everything else in the wiki/forums):
First I updated alsa using this method: http://forum.linuxmce.org/index.php/topic,11932.0.html (http://forum.linuxmce.org/index.php/topic,11932.0.html)
and installed nvidia update
Then I followed the HDMI Output Does Not Work instructions on: https://wiki.archlinux.org/index.php/Advanced_Linux_Sound_Architecture#HDMI_Output_Does_Not_Work (https://wiki.archlinux.org/index.php/Advanced_Linux_Sound_Architecture#HDMI_Output_Does_Not_Work) to find my card number and device number
Then i wrote those numbers down and created the ~/.asoundrc file in /root and /home/<kubuntu user directory>
Then I edited /etc/pluto/xine.conf and set:
audio.driver:alsa
audio.alsa_front_device:plughw:1,9 (1 being your card number and 9 being the device number you found with aplay)
Hope this helps someone.

Creating the ~/.asoundrc files didn't help me. I had to put the following into /etc/asound.conf:
plug pcm.!default {
type hw
card 0
device 7
}
After rebooting the MD (reloading the alsa modules didn't work and I didn't want to waste time figuring out why), HDMI sound finally works!
I know /etc/asound.conf can be overwritten, so I would lose my custom config in that event. But, I my changes will survive MD reboots. So, if I rebuild the MD image, I'll likely lose the customization. Am i right?
