Hello all

My receiver Sony Str-dh590
AppleTV4K audio setting -Auto/Best Available and Infuse setting -auto
Is infuse sending multi-channel LPCM to receiver, right?

But my receiver sometimes get 5.1LPCM or DD5.1 when I play TrueHD5.1 or DTS-HD MA movie.
I didn’t change my audio setting.
Is this my ATV problem…?

This sounds like an Apple TV problem. The AppleTV should send either LPCM or DD5.1 depending on what you have set in settings.
