Windows 10 - HDMI Sound Lost After Standby

Since upgrading to Windows 10 I have this issue where the HDMI sound stops working after a lack of activity or I come back to my pc after a while when the screen has has been in standby (woken by moving mouse or keyboard press).  I cant quite work out if this is every time or randomly, but when it happens videos start to play either locally or on youtube etc.


The only way I can get the sound to start working is to either disable and re-enable in device manager the AMD High Definition Audio Device under Sound, video and game controls or reboot the system.


I've tried both official and beta drivers and both exhibit the same issues, so any help in resolving this would be appreciated.
