Sound issues in Ubuntu

If you get some faint crackling sound in the speakers and nothing else, the way I did with the Conextant/NVidia sound card then run this command

alsamixer -Dhw

It is possible that the PCM Mixer volume is muted or set to zero. When you run that command, you will be given a text interface which you can control using the arrow-keys. (I think such interfaces are known as CURSES interface, for some reason) You should navigate to the mixer section, which I believe is the 2nd option and turn it all the way up.

More later
