Disconnecting randomly D6000 dock

[pretendent]

I've got an issue where my monitors randomly disconnects using D6000 dock with Dell latitude 5591

Already tried editing /etc/pulse/default.pa

### Automatically suspend sinks/sources that become idle for too long
# load-module module-suspend-on-idle

But still experiencing disconnects, the most annoying thing is i need to reconfigure input/output devices every time.

Tried reinstalling drivers several times.

Adding support output

Check if ubuntu is auto suspending the USB/Type-C port

autosuspend is disabled. Now it's happening 2-3 times/hour

I have the same issue, but only after 5 minutes of playing a video or other demanding graphic task.
Is it the same for you, @pretendent?
