Very new to Ubuntu but have checked some of the other posts and tried some suggestions but keep getting the same problem. Did a clean start and the sequence of events is as follows

1.Instal Ubuntu 12.10 2.Instal VLC 3.Play songs/video without problem

Alsamixer display has Master,Headphone, Speaker,PCM, mic etc

After restart.... no sound and Alsamixer only has PCM displayed!!
