It's simple, play the audio you'd like, then choose the video input you'd like to play on the display. Saving it as a scene is possible - but then it means every time you use that source (say USB) it will default to that video source... which is obviously not always ideal. One the RXA1060 / 2060 / 3060 you can use the advanced Scene selection option to fix this... below this, it's a little trickier to automate. However it IS possible for a relatively savvy consumer to use the option button themselves.
...those customers are rare though.
This industry is not getting cheaper and cheaper, we're simply convincing ourselves that we have to push the cheapest option to customers. #makesonosgreatagain
