I had similar problem for a while on Ubuntu 9.04 beta on HP nx6110 notebook. The sound disappeared after installing a few audio players using MPD 0.14.
Sound works again after removing MPD and some of the installed audio players (Sonata 1.6.1 for example). Please have a look at the Sound Preferences settings and restart your system. -- Hp-compaq notebook,no sound in ubuntu 9.04 https://bugs.launchpad.net/bugs/360137 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
