Yeah, Sound was working. I wanted to try upgrading the driver for the possibility of better sound quality.
I take it then that you have tried the audio under another OS and enjoyed the quality more? Can you describe what is wrong with the quality under the linux driver?
Have you tried upgrading the installed driver? - with the *buntus this is very easy
I decided to go look - according to the readme that comes in the tarball, the source code is already in the kernel - it comes from the alsa project. In fact, your configure line is:
We used to see sound quality issues
with these chipsets, but they have pretty much cleared up in recent kernels.
So - it looks like you are doing far more work than you need to.
The main difference from the readme is that ubuntu relies more heavily on pulseaudio ... so alsamixer works but alsaconf does not. From all this, I feel I must strongly urge you to install the latest mainline kernel and see if there is any improvement that way.
