Headphones muted after startup

June 9, 2019 - ubuntu

To tell pulseaudio that headphones are always plugged in, edit the /usr/share/pulseaudio/alsa-mixer/paths/analog-output-lineout.conf file.

Try to find the following lines in the file:

[Jack Headphone]
state.plugged = no
state.unplugged = unknown

And, if they exist, change state.plugged = no to state.plugged = yes.

Next, try find the following lines:

[Jack Front Headphone]
state.plugged = no
state.unplugged = unknown

Similarly, change state.plugged = no to state.plugged = yes if the lines exist.

Next, find these lines (if they exist):

[Element Headphone]
switch = off
volume = off

Change switch = off to switch = on here.

Also try to find these lines:

[Element Headphone2]
switch = off
volume = off

If they exist, change switch = off to switch = on.

Save the file and, finally, restart pulseaudio:

$ pulseaudio -k
$ pulseaudio --start


Just found a working fix for my hardware: tell Pulse to control just one mixer control.

1. edit /etc/pulse/
2. uncomment the line that says

#load-module module-alsa-sink

3.change it to

load-module module-alsa-sink control=PCM
