No sound PC w/windows 10 via HDMI

I have two laptops with Windows 10 and until recently I have been able to hook up both to my TV via a HDMI cable...worked great for years, now when I try it, picture is fine on both but no sound from pc or TV. For both to stop working it occurred to me that maybe a darn Windows update could have created this problem. I have gone past the 10 days whereby I understand I could have gone back to a previous version of Win 10. Anyone else had this problem or more to the point have a solution ?

 

I am going to assume that you tried a different HDMI cable with no luck.

 

Open this Google link and start at the top --- you should find a solution here.
My HP Laptops always after a MS Update default the sound to MAX which is a pain in the butt.
I'm used to it now so I would suggest that an MS Update has probably switched off your HDMI as explained in the videos.

Correctly assumed
