I am using Ubuntu 10.10 and my sound stopped working. It had happened before and I had a vague recollection that reinstalling something worked so I did:
sudo apt-get purge pulseaudio sudo apt-get install pulseaudio sudo apt-get purge alsa sudo apt-get install alsa
but now even the volume control icon is gone. I also tried this later:
sudo apt-get --purge remove linux-sound-base alsa-base alsa-utils sudo apt-get install linux-sound-base alsa-base alsa-utils
, but still the sound is not coming .
