Laptop speaker not working (elgato game capture)?

I recently bought an elgato sound capture, before that everything was still ok with the loudspeaker, but now he no longer recognizes the loudspeaker and I get the error message elgato sound capture is deactivated

How can I solve this problem

Hy,

did you try to update the drivers in the device manager or reactivate them there?

if not, you should take a look there and check if a driver is missing.
