I have one Yamaha Rxv685 receiver paired with LG C9 OLED TV both compatible with Dolby atmos. Both systems are connected through ARC. Unfortunately though the audio available with the TV is Dolby atmos, audio output from the receiver is Dolby Digital plus. I am streaming Dolby atmos content from Netflix. Owing to this problem though the audio format available with the TV is atmos , I am not getting the benefit of it. Any suggestions to circumvent this issue please help me.
