Woops. Turns out it was a Java application for me, (as GrayFox mentioned). Closing Vuze (aka Azureus), brought the sound back. I guess I'll be looking for the option to turn off sound notifications in Vuze then... (if that helps)
If anyone can point out how other people can find out which application is blocking the sound card, I'm sure it will help others here. Looks like it's not just Firefox/Flash/Pulseaudio -- "xine was unable to initialize any audio drivers." error https://bugs.launchpad.net/bugs/68187 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
