nvidia hdmi audio woes

[Joe Born]

crweb,

Not sure what your progress is on nVidia and HDMI audio (for the
prototype links), but I got it working for everything except flash
using this advice:
http://www.goingson.be/2008/12/ubuntu-and-hdmi-audio-output.html

now I can play an mp3 and get audio via HDMI, but hulu still doesn't work:

I guess next I'll try this:

do we need to nuke pulseaudio? That seemed like an effort

well, nuking pulseaudio didn't seem to help. Surprisingly even win
firefox on wine has the same result, video plays, but no audio. I've
tried re-installing flash with no result. there's even an extrasound
package for nonfree which didn't seem to work.

The only thing I haven't done is re-tried getting flash to work with
pulseaudio, but that caused so many problems in the past, it seems a
waste to bother.

Help!

This is over a year old. But you lose nothing by trying...

That article had you configure gnome's output (which, I guess, is
probably gstreamer), not alsa...

Looks like I get to have fun when you send me one of these boxes, I'll
be using HDMI audio...

After you left, I didn't get much further with 9.10.  I installed flash, removed pulseaudio with synaptic, then installed the latest nvidia and alsa drivers, once I removed pulse I couldn't access the gnome sound control panel, it would give some error.  Also, that  ~/.asoundrc file you reference didn't exist at all, so I created one with the lines you suggested, but I still couldn't get audio from HDMI.

latest alsa drivers? I didn't install any newer alsa drivers than what
9.10 had.

Ok, first thing, make sure you restarted Firefox after the .asoundrc
change.

Second, try 'speaker-test -c2 -D hdmi' and 'speaker-test -c2 -D hw:0,3'
and see if those work. If not, post output of aplay -l.

And finally, for anyone else who has this problem: make sure the HDMI
IEC output isn't muted in alsamixer. That one is important!
