I am using Ubuntu 10.10 Maverick Meerkat. I have a sound issue, (with a Realtek sound card, though I am not sure which one.) Everything was running fine for me until I decided to install the drivers from the Realtek website. I followed their instructions, but couldnt get the sound to work after the reboot.

I tried the solutions suggested in the Comprehensive Sound Problem solution guide, but it has not worked. The problem is I cant figure out which soundcard I have, as it is not detected with aplay -l and not listed under lspci -v

Any suggestions please? I would hate to re-install, although it would solve the problem.
