I am running Xubuntu 12.10 and I was trying to repair the sound on the headphone jack since I had sound output through there and now I have no sound what so ever. So I think I made things worst. No sound through the speakers and no sound through the headphone. I know I did something wrong but I don't know what I did. I have pulseaudio. If I could at least get the speakers working again I'll be happy. Any help will be highly appreciated!
