Suppose you have not so good eyes like me, and your nice Nvidia cards HDMI video out looks nicer and is easier to read than the VGA out, but you're having problems getting the sound to work. Not only that but if you use the HDMI audio out, you lose sound to your headset jack in front. Sure since my monitor is a small HDTV I could just run a short extension cable from my TV's headphone jack to reach to the plug on my headset leaving the mic jack plugged in as normal, but that's annoying.
Well here's a solution:
First lets get your Nvidia audio out working, this helped a lot since I have a GT220:
I did what it says to edit /etc/modprobe.d/sound.conf in my case it's a single lin
options snd-hda-intel enable_msi=0 probe_mask=0xffff,0xfff2
then edit /etc/pulse/default.pa
after the section that says this and a bunch of commented out stuff:
### Load audio drivers statically (it's probably better to not load
### these drivers manually, but instead use module-hal-detect --
### see below -- for doing this automatically)
then add this:
load-module module-alsa-sink device=hw:1,3
and then if you want output to BOTH HDMI and Analog add a:
at the end.
reboot, unmute card 1 in alsamixer or alsamixergui (it's muted by default!) and select simultaneous audio out in pulseaudio, if it isn't already.
Hope this helps someone down the line:
