Selected Sound Output Device Not Persisting Between Reboots in gnome-control-center

Each time I reboot Ubuntu 19.10, I have to open gnome-control-center and set the sound output device back to my Laptop’s Built-in speakers. Otherwise, it will typically default to DisplayPort devices that don’t even have speakers.

enter image description here

Which file are these settings saved to? I’m thinking that maybe that file is corrupted and that if I delete that file maybe Ubuntu 19.10 will start remembering my sound output preferences. I’m also open to other suggestions.

Here is Solutions:

We have many solutions to this problem, But we recommend you to use the first solution because it is tested & true solution that will 100% work for you.

Solution 1

I have had the bug report suggestions setup this way for along time as sound is always routed to TV and I don’t want it to switch to tinny laptop speakers.

Use sudo -H gedit /etc/pulse/default.pa and find the lines:

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

Change them to:

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

Save the file and use: pulseaudio -k

Note 1: It’s been reported that plain sudo now performs like sudo -H in 19.04 but caution dictates using later method.

Note 2: Earlier versions of Ubuntu will only have the first configuration line.

Note: Use and implement solution 1 because this method fully tested our system.
Thank you 🙂
