Ubuntu – Mute key mutes Alsa and PulseAudio, but unmutes only Alsa


When I press the mute key on my keyboard, both the Alsa master channel and the PulseAudio master channel get muted, pressing it again only unmutes the alsa master channel, the pulseaudio master channel keeps muted. Result: no sound.
How do I fix that?

Run this command:
