Title:
Speaker audio channel goes mute after plugging in the headphone
Status in “alsa-driver” package in Ubuntu:
Triaged
Bug description:
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/pulseaudio/alsa-mixer/paths/analog-output-headphones.conf
and commenting the line as here:
[Jack_InputDevice]
#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.
