Nvidia HDMI out and Analog audio out combined!

[CronoCloud]

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:

http://wiki.xbmc.org/index.php?title...T220,_or_GT240

I did what it says to edit /etc/modprobe.d/sound.conf in my case it's a single lin
e:

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:

load-module module-combine
set-default-sink combined

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:

Just a note of thanks, as I was able to use this to get a GT220 HDMI connection to work as advertised.

One problem with F16, loading the combined sink module makes Pulseaudio unstable and causes it to almost immediately crash upon use. (just reinstalled my GT220 since I finally got another upgraded power supply)
