Subject: I can only get 2-channel audio on my A/V Receiver when viewing one source on multiple displays.
Explanation: When multiple displays are viewing a single source, the source will output a common format that all screens can handle. So when all of the sources do not have A/V Receivers the source will default to a common 2-channel audio format. In order to get multi-channel audio to the AVR, you need to assign a multi-channel EDID to any source that you want a multi-channel signal from. Some displays may not be able to downmix a multi-channel signal and will result in no sound or a repetitive clicking sound.
To resolve audio/video issues, Atlona recommends performing an EDID learn using the steps outlined in this article.
