First off, I tried to send this in as an email after following
this post. But that inbox is full, according to the automatic reply I got in Chinese(?).
So over to the problem.
I had this audio related problem with Netflix since I upgraded to Windows 10 and the Beta sound card drivers. Every time I try to play a video on the Netflix app or in browser(s) I get a error code (W8156-88890001).
The fix to this problem is a Registry edit change. Windows button > Run > Regedit > HKEY_LOCAL_MACHINE/SOFTWARE/Microsoft/Windows/CurrentVersion/Audio and change the DisableProtectedAudioDG from 1 to 0 and restart the computer.
After I have done this Dolby Home Theater V4 will not work before you change it back from 0 to 1.
Would be nice if this got a fix in the next update.
