Did you go into alsamixer or another mixer app and make sure that no audio channels are muted?
By default, one of my systems had the Surround channel muted (which mutes everything) and the PCM volume set to 0 (which was muting audio from VLC and media players but not the system sounds). -- ubuntu karmic no sound https://bugs.launchpad.net/bugs/504972 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
