Speaker audio channel goes mute after plugging in the headphone
Speaker audio channel goes mute after plugging in the headphone and unmute after the headphone is plugged out. By consequence there is no sound when trying to listen the sound by headphones.
This is a pulseaudio problem and can be circumvent by just editing /usr/share/
#code = Headphone
This will avoid pulseaudio to change profiles when headphone is plugged in.
Some people affected by this bug don't get the headphones muted, but only a very low volume, this workaround could help too. But to some computer models this workaround could let the sound play by headphones and speaker by the same time (most people don't desire that).
On my computer model ( HP Pavilion DV-4 2080br ) the workaround works well and the sound goes only by the headphone, as expected.
