I hit mute a couple of times. The mixer shows its unmuted, the menu for the tray icon shows its unmuted, but the on-screen display thinks its muted and no sound plays.
I restarted. The tray icon shows muted. I unmuted it, but there is no sound.
I then went to KDE and unmuted. This is a successful workaround.
Is there a way I can mute and unmute with XFCE?
My system is XFCE with Kubuntu 15.04, maybe an unusual combination. How to solve this?
Answer
You can try
alsactl init
which initialize all sound devices to a default state.
