Headphones muted after startup

Question

Headphones always on mute after startup PC or killing pulseaudio by pulseaudio -k

It can be unmuted in alsamixer or in terminal amixer set "Headphone" unmute, but do this after each startup is annoying. I created a script and added it to "Startup Applications", but it doesn't work.

#!/bin/bash
amixer set "Headphone" unmute

Also tried this and this guides, same result. Headphones connected to Front Panel by 3.5 jack.

Solution 1

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

Solution 2

Sorry, I don't have enough reputation to comment Zé Bento's post.

What worked for me was changing both Jack Headphone's and Jack Front Headphone's state.plugged to unknown.

I don't know the meaning of that, but that was the default value for all other input types in my files.

Thanks! In my case, i only had to change this [Element Headphone] switch = off volume = off

Also you may want to change volume = off to volume = merge otherwise you won't hear anything because volumen will be at 0
