Here's one more weird thing. I just had this situation again. No sound at all.
I clicked on SWITCH USER in the Gnome menu. After having been presented with the choice of users, I chose myself, logged back in into my continuing session. That cured the problem! -- All sounds stop working after long inactivity, firefox restart cures it https://bugs.launchpad.net/bugs/491460 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
