What I had done to recover the audio on the Windows 10 guests were to update manually the driver of the 'Unknown Device' or 'Multimedia Audio Controller'. Assuming you have a backup (either from a snapshot or disk backup) or another unaffected VM guest, check to see if you have the C: Program Files Common Files VMWare Drivers audio folder in. I downloaded windows xp on my computer and when i did that it deleted my multimedia audio controller driver and i cant figure out how to fix it. I tried the original disc but it doesnt work.
