--- Comment #12 from Mark Wilczynski <Mark_Wilczynski at hotmail.com> ---
I'm primarily a Windows developer so I temporarily moved my testing over there.
 The Windows 10 results were surprising.

When I played a 44.1 kHz audio test while running a full-screen-exclusive D3D
app with 36-bit scan-out, the sound DID NOT work.  Same results as in Linux. 
48 kHz audio worked fine with 36-bit color output.  One difference was that I
didn't see any dropped or skipped video frames like I do in Linux with 36-bit
color enabled.  This means the audio/video clocks are in proper sync for 59.940
content and 59.940 screen mode.

So either 36-bit color at 1920x1080 at 60 + 44.1 kHz audio is broken in both
Windows and Linux or this TV does not accept that combination despite listing
it in the EDID.  When I plug it into my Denon AVR, everything works fine using
36-bit color in Windows but it's no longer using the TV internal speakers.  The
AVR reports that it is receiving 36-bit color and 44.1 kHz audio so I assume it
is still passing 36-bit color to the TV.

I will try to get a second opinion by using a non-Intel GPU with this TV to see
if it has the same problem.
