Hab gegoogelt und folgendes gefunden:
How to fix No Sound on Windows 10 issue
Right-click the sound icon in the taskbar located at the bottom right of the screen and select Playback Devices from the ensuing context menu.
Select the current playback device in use and by default it should be the speakers. Double-click on it to open its properties window.
Got to Advanced section and change the bit rate to either of the following - 24bit/44100 Hz or 24bit/192000Hz - depending on the speaker configuration.
If the issue is still unresolved, you can try another method for restoring sound:
Launch Start Menu
, search for Device Manager
and then launch it.
Expand Sound and audio devices
Step 3: Right-click
on the current sound driver
and choose uninstall
Finally, click on Scan for hardware changes
and the updated driver will be automatically installed.
Keine Ahnung ob das hilft. Mal probieren, bitte
