[mythtv-users] Make your NVidia GT-2XX card hdmi sound work!

[RALPH KEMP]

Got this to work this weekend on Ubuntu 9.04 with mythtv.22.  Someone in
another site/forum said to modify /etc/modprobe.d/alsa-base.conf and add
this line to it:

options snd-hda-intel enable_msi=0 probe_mask=0xffff,0xfff2  (if your Nvidia
card is card 1)

And to create this file in your home directory:  .asoundrc

with this info:

pcm.!default {
type asym
playback.pcm {
type plug
slave.pcm "hw:1,3"
}
}


The WIKI said to modify /etc/modprobe.d/sound.conf - I don't recall touching
that file - but it does exist - and has that same options line above in it.

I'm using the HDMI interface on this card btw:

Also I removed the ALSA packages alsa-base and alsa-utils  prior to
downloading/compiling Alsa source.  Since that removes alsamixer and aplay I
had to download alsa-util source and compile/install also.   If the linux
gurus could comment on the need for that would be great.

The above info is only is your Nvidia card is for card 1.....from some
digging I found this information - I think it's correct but YMMV....

options snd-hda-intel enable_msi=0 probe_mask=0xfff2 = Card 0
options snd-hda-intel enable_msi=0 probe_mask=0xffff,0xfff2 = Card 1
options snd-hda-intel enable_msi=0 probe_mask=0xffff,0xffff,0xfff2= Card 2
