Comment 4 for bug 549514

Daniel. I understood part of your suggestion and have added the ppa to my software sources. Once this was installed, I was able to install the alsa driver from synaptic.

This resulted in improved stereo sound, but no options to do the 5:1 surround sound. The headphones still do not work.

I don't understand the second part of your instruction, to put the appropriate (uname -r) after -modules. But at least the sound is better than it was. Thanks!
