When I press the media keys I can hear the 'pip' sound telling me what the volume will be, so somehow that can use the sound hardware.
Thinking about it, while I can't be sure, it seems quite unlikely that sound would have been broken for me for a week without me noticing (implied if it happened at login time). I wonder if it broke somehow at runtime. laney@iota> loginctl show-session c2 Id=c2 Timestamp=Sat 2013-07-27 10:41:27 BST -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1197395 Title: /run/user/$ID/pulse owned by root and not by the user To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/pulseaudio/+bug/1197395/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
