How to reset audio on Windows?

Yes.

Go to an elevated command prompt and type net stop AudioSrv followed by net start AudioSrv

or right click on Computer, click on Manage and expand Services. Right click on Windows Audio and click restart.

FWIW, I created a batch file that does the whole kit-and-kaboodle (including UAC prompting)
