4K ATV Audio Output to AV Receiver

HDMI switching

The manual for your model receiver only talks about Component Video Switching. I’m not 100% sure what you mean by ‘HDMI switching’.

I initially connected the HDMI cable to the HDMI switching on the receiver, however this proved unreliable with lines across the TV screen (like an interference) and then the receiver simply not carrying out the switching at all. I have assumed the HDMI switching in the receiver is faulty.

This is concerning, as it should just work. No setting can fix broken hardware. A digital signal shouldn’t have anything like analog interference.

My Panasonic TV has Toslink audio output so I have reconfigured with HDMI from ATV direct to TV then Toslink from TV to AV receiver. This, so far is working fine except the receiver is no longer auto-switching to the audio being output from the ATV. I have checked the settings in the receiver which is correctly set to automatically select a listening mode corresponding to the audio input received.

This should also work, but the receiver would only know about getting audio from the TV, not what other device is connected to the TV.

To have the receiver (or TV) automatically select to the wanted HDMI port, you may have to activate HDMI-CEC on the Apple TV, if it wasn’t already. Settings﹥Remotes and Devices﹥Control TVs and Receivers﹥On|Off.

To mimic your old situation, with a direct audio connection over Toslink, you could buy a HDMI Audio Splitter, which could provide an external optical audio connection socket. I would prefer HDMI all the way, but it is a possibility.
