This JUST bit me 🙁 4/2017 And I’m a Computer Pro and nerd! Wasted 90 mins doing safe mode, System Restore , Hardware Changes, etc then eureka 🙂 Control Panel/Device Manager/Sound and double click your Sound Card…Driver Tab….Disable your Driver……click OK and exit out
Go back in and ‘Enable’ it. Click OK
Worked for me 🙂
If that doesn’t work…then YES uninstall and download new driver and install!
Rolled back driver for HDMI Audio. Problem caused by updated AMD Catalyst. HDMI Audio working again with original driver.
