Sometimes No Sound

From time to time, sound is not available. It happened on Monday, resumed working on Tuesday (yesterday) morning but since Tuesday evening my computer remains silent.

Sound Device

My sound device is detected:

excerpt of my configuration:

  enable = false;

Where should I look for the problem?
There are so many logs (dmesg, journalctl, …) available…

Thanks for any hint.

forgot to say:
With the Windows :face_vomiting: laptop of my employer, the sound works well.

Hello
So my first question would be what you did in the time between where it worked and then it did not work anymore. For example have you done a reboot, moved something physically or anything else.
Also how is your system connected to your sound-system?
Next would be to look for errors on the software side. Therefor first try it with pulseaudio and see if that solves the problem. Additionally can you post your journalctl and dmesg logs of the time where the sound went away? Those you can post on pastebin.com and share the link
