Support Dolby TrueHD with Atmos passthrough
On Windows 10, passthrough is working for Dolby TrueHD and for Dolby Digital Plus with Atmos. But TrueHD with Atmos is not working. I tested 3.0.11 and also nightly build 20201125-0425. When I try to enable this audio track, the soundbar detects no input and the log shows:
mft error: Could not find suitable MFT decoder
main error: could not identify codec

My hardware is a GTX 1080Ti connected to Vizio 5.1.4 soundbar so this format should be possible. I don't know of any other software to test this format. Sample clip is here: https://we.tl/t-ILkyOtizIY along with many others at https://thedigitaltheater.com/dolby-trailers/
