How do I set the default audio device?
 
I'm running Linux Mint 10 LXDE.
The device I want the system to forward all audio output through is the HDMI on my ATI 4350 video card. I have it working in VLC, all I had to do is go into the preferences and set the

Output Module to ALSA audio output
and
Device to HDA ATI HDMI: ATI HDMI (hw: 1,3)

Now I can play clips through vlc..which is great, but understandably I'd like to go ahead and make it so that entire system is doing the same thing VLC is doing right now. I've searched and searched and read through and tried a few different solutions but I really don't know what I'm doing or really where to start reading for a start to finish explanation of exactly whats going on here.

less /proc/asound/modules gives:

0 snd_intel8x0
1 snd_hda_intel

aplay -l gives:

I've tried setting
options snd_intel8x0=-2

to "black list" the device that was being set to default instead of the one I wanted

and I've tried commenting out the

#options snd-atiixp-modem index=-2

line because it contained the "ati" string.

Please help, thanks.

solved. I disabled the other sound card in the bios and installed the gnome version.
