No Audio since a day

Hello, I have the problem that I have since a day no sound. I am using a DisplayPort cable to connect the PC and the monitor.

Here are the command outputs:

systemctl --user status pulseaudio.socket

Moderation Note: Changed output formatting.

And this is on all kernels?

Hello @Independent-Eye
Display port does support audio output. What is your output to sound? Do you have sound going to speakers from your sound card from line out or? Could you post the output link for

OK, after unplugging all devices, it works again. But I have no idea why it didn’t work
