I met with this weird problem today, No sound output from my system with any player say banshee, totem etc... But yesterday it works fine. I checked all the sound settings in volume control it seems everything is perfect, but no sound output :(. Atlast i got the solution for this. Just give the following command in the terminal as root.
#alsactl init
The above command initializes the alsa sound card driver :). So after this audio works find
My audio driver is
:~$ lspci | grep -i audio
00:1b.0 Audio device: Intel Corporation 82801JD/DO (ICH10 Family) HD Audio Controller (rev 02)
