AAC sound playback on mp4 and MOV files

Hi , am new here and have issue of playing aac sound on mp4 and mov files lately. I’m using harman/kardon avr and aac audio files played with no problem before.  I already unchecked AAC capable reciever in the Audio set up, but still problem is there. What is the issue and can this be fixed?

Does it happen with all files with the AAC audio format or only certain files?
