As a bonus, this also upmix stereo sounds to 5.1ch. Yes you can say its no longer a "pure" audio, but for me, it does sound good. Maybe can be disabled thru Dolby Home Theater control panel (i didnt install it, so dunno). Alternatively you can set the output format back to PCM instead of Dolby Digital.
PC games often outputs surround audio in LPCM, making surround system only outputs stereo as HDMI ARC only supports stereo LPCM. Making a surround capable AVR (and 4K HDR capable too, if you use 4K HDR TV) a necessity.
