Ubuntu – Output channel for audio resets after every reboot

sound

I use my "Line Out – Built-in Audio" for my speakers, but for some reason, every time I reboot my computer, it changes by default to "Digital Output (S/PDIF) – Built-in Audio".

The funny thing is that, if I unplug and re-plug my speaker connector, the channel changes by itself to "Line Out" without me having to do anything.

What could I do so that I can stop doing this annoying step every day?

You can have pulse audio stay on the last selected output source no matter what:

sudo -H gedit /etc/pulse/default.pa

Find this line:

load-module module-switch-on-port-available

and change it to:

# load-module module-switch-on-port-available

An additional step is needed as listed in:

We need to add the line:

set-sink-port <name|index>  analog-output-headphones

The name or index of the active sink, and available ports can be displayed with pactl list sinks. The way I spelled analog-output-lineout may be incorrect.

Save the file and exit.

Restart pulse audio with:

pulseaudio -k

In your sound settings select "Line Out" and it will always stay connected even if you physically unplug it.
