Hello,

I have recently purchased and connected via HDMI ARC port.

I'm using Zeb-9400 5.1 Dolby Sound bar which works fine when connected Mi 4k Box with Optical Cable, it produce real 5.1

But when connected with Zeb 9400 ARC to Redmi ARC, only stereo files play well and when tried to play 5.1 there is no sound.

Kindly help, OS of tv: Andriod TV 11
