DisplayLink crash sound devices in Linux Mint 21.2
I use ICY BOX USB-C Docking Station (IB-DK2242AC) together with Linux Mint 21.2 together with the latest DisplayLink driver (Release: 5.8 | Aug 9, 2023).
From time to time, the sound crashes. All sound options (devices) disappear. When I disconnect my docking station from my PC, then the sound option (devices) comes back. Therefore, I think DisplayLink is the cause to this bug. Similar problems also happened on Ubuntu 22.04. This a new problem. Most probably is related to the release 5.8. Does anyone have similar problems and got a fix? I will try to downgrade the driver when I get time. |
pulseaudio service
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 If it complains there's no process running, just sending this will start the process: Code:
pulseaudio 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 |

I ask because I am curious if an external device connected to the dock (and not the dock itself) is contributing to the unexpected behavior. |
You were little too late. It happened sometimes 10 times per day. In the end, I decided to switch to Ubuntu 22.04. Now it happens 1-2 times per week. Next time it happens, I will let you know.
In Ubuntu 22.04 however, I got lot of other problems which can be read in "Problem on new Ubuntu 22.04" |
