Default Re: Nvidia GeForce GT 220 + Ubuntu 9.10 = No audio over HDMI?

Where you have 2 sound cards, you may need to try
options snd-hda-intel enable_msi=0 probe_mask=-1,4

Alsa does seem to recognize the nvidia hdmi.

$ aplay -l

This is how I tried to check if alsa works.

My onboard sound card with stereo output works with this command.
$aplay -D plughw:0,0 /usr/share/sounds/alsa/Front_Center.wav

But no sound on my TV when I try to check hdmi audio output.
$ aplay -D plughw:1,3 /usr/share/sounds/alsa/Front_Center.wav
Playing WAVE '/usr/share/sounds/alsa/Front_Center.wav' : Signed 16 bit Little Endian, Rate 48000 Hz, Mono

Any ideas/suggestions? Should I try a different probe_mask in my sound.conf?

Thanks.
