DisplayLink crash sound devices in Linux Mint 21.2

I also had this issue, 21.2 Cinnamon, and it happened after installing the Displaylink drivers. I thought I was going crazy missing sound and audio.

My issue was that the pulseaudio.service was removed from user startup. If you wanted to verify this is the issue, in a terminal, you can send a

Code:

pulseaudio -k

That "kills" and restarts the process.

If it complains there's no process running, just sending this will start the process:

Code:

pulseaudio

You should then see your pulseaudio icon in the tray, and sound would be restored. But the process is running in a terminal, so closing it would end the pulseaudio process.

To add to startup permanently:

Open Session and Startup (from Mint Menu)
Choose the Application Autostart Tab
Click the + sign at the bottom Left
Name: Start PulseAudio
Description: Start PulseAudio Service
Command: systemctl --user start pulseaudio.service
Trigger: on login
