Volume is always on max. The volume indicator is showing three dashes and does not show anything when I click on it. Clicking the "sound" button in settings causes it to recursively reopen settings. pulseaudio --start doesn't help.
EDIT: This has only started happening after the upgrade to 13.10
EDIT 2: This is in Unity, yes.
killall unity-panel-service works and does reload the panels, but previous problems persist.
EDIT 4: alsamixer seems absolutely fine.
