My sound stopped working an I don't know why.
The GUI and the terminal are telling me different things.
The top bar shows the speaker symbol with three dashes. It looks muted.
It used to show a volume slider when I clicked on it, but now all I get is a small gray rectangle. The print screen button stops working when it is visible, so I can't capture it.
In the terminal, amixer says the Master volume is unmuted and 100%.
$ amixer get Master Simple mixer control 'Master',0 Capabilities: pvolume pvolume-joined pswitch pswitch-joined Playback channels: Mono Limits: Playback 0 - 64 Mono: Playback 64 [100%] [0.00dB] [on]
The terminal is misleading; the GUI is being downright weird.
How do I get the sound back?
