Public bug reported: I have dual-booted Ubuntu and Windows and I don't have sound at all. Before when restart laptop sound back shortly but if I boot it again there is no sound anymore. Interesting, when type alsamixer I get cannot open mixer: No such file or directory. I'm noticing that I have installed driver. Sound sometimes works sometimes not
