This article aims to help you troubleshoot and fix sound problems. More specifically, several Mac users have reported that they are unable to change/adjust sound/volume.
Do you think that your Mac’s volume control is not working?
One possible change is to control the size of the expansion of the Stuff volume. Apple's default is to take all the free space created by deleting the second volume and apply it to the first. If you would rather add a smaller amount, you can do so by selecting the Stuff volume, entering a new size in the Size field, and then pressing Return. What was surprising is that Apple finally moved on from the ‘10’ (or ‘X’) version number. After nearly twenty years of ‘ten-dot’ versions (more when you consider Mac OS X Server and the Mac OS X public beta) macOS ‘Big Sur’ is labelled as version 11.0.

Make sure you have the correct device for your audio selected.
