I got Knoppmyth ocmpletely set up, it went pretty smoothly except that, for the life of me, I can't get any sound. I am using an AMD 939 Motherboard, which has nVidia High Definition audio onboard.

lspci reports the following about the audio controller:

Code:

I can't get any sound from the TV card or from anything else. Has anyone ever set up this card, could you give me some pointers as to where to turn.

Sorry if this post is incoherent, my mind is fried from wrestling with this thing all day.

Hi,
Until the resorces that can positively help jump in, I can at least offer some ideas to try. As root:
#alsamixer #sometimes things are (m)uted, if it errors then run the following command....
# alsaconf #to see if it can find your card and make it work

if you do a find, there are a few wav files on the system that you can use for testing.
# find / -name *.wav #should show you some files to listen to.
# play <the-full-path-to-the-wav-file>

Mike
