I have a harman kardon avr171 receiver and harman kardon 7.1 home theatre system. With blurays or games on ps4 7.1 works just fine but when i try playing 7.1 movies on plex app on ps4 my avr shows only 3/2/1 5.1 active channels?
Ps. On wdtv live those movies with dolby true hd or dts ma 7.1 work fine too and avr shows 3/4/1 7.1.
Thank you
