I have two Chromecasts. One is connected to a receiver that supports 5.1, and it works fine when I cast to it. The second Chromecast is attached directly to a Sony TV.
When casting Plex to the Sony TV, I am able to use the volume control on my phone to control the volume of the Chromecast, so long as the media is 2 channel. If I cast media that has 5.1 channels and try to use the phone to change the volume, I get the “Surround sound enabled” message on the screen.
As this is just a TV with two speakers, there really is no need to send 5.1 channel audio, and it would be great to be able to control the volume with my phone, and by extension with the Google Assistant.
How can I force Plex to always transcode to 2 channel audio when casting to a particular Chromecast, while retaining 5.1 channel audio when casting to another Chromecast?
