Someone insists that bug 549514 is a duplicate of this bug. That bug is trying to get sound working correctly on an Acer Aspire 8942G (quite a different machine than the Acer Aspire One). I have run two commands that may provide some additional information. The output from aplay -l and lspci are shown below.

To my eyes, it appears that ubuntu is loading a generic sound driver instead of the sound driver for the specific card, but I am not an expert. If someone who has more experience could take a look, and maybe suggest a solution, then I would be most grateful.

I am comfortable editing configuration files (like /etc/modprobe.d/alsa-base.conf), but I am not ccomfortable compiling programs. As long as the instructions are detailed and complete, then I will be most grateful for any help you can give me.

Many thanks,
