Intermittent Garbled Audio - Apple TV 4K & Denon X3600H
I have an Apple TV 4K connected directly to my LG OLED C9 TV. The TV is connected to my Denon AVR-X3600H Amp via HDMI e-ARC.
It all works fine, with no issues in playing stereo or Dolby Atmos audio. However all other surround audio comes up as ‘Multi In’ on the amp (I understand this is expected for AppleTV). Normally this is fine too but I have an intermittent issue where the audio produced is totally garbled. This issue only occurs when first playing ‘Multi In’ content and can normally be fixed by exiting the content and re-playing.
It’s frustrating though. I've tried changing cables and have the latest firmware on everything.
Any ideas?
