Have never got an answer to this, I still love to know - I do see other posts, although, AFAICS, there’s no definitive answer. If it is answered, I apologise.
Why does AAC 5.1 audio only work when casting via the mobile app and not via Chromium browsers? AAC Stereo is fine.
I am also looking to get a 5.1 AAC transcode in the web player, have tried the “force multi-channel” option but that seems to only apply to Chromecast. I am looking to play 5.1 audio from my PC’s web browser to my 5.1 Windows audio device, specifically from Microsoft Edge. Supposedly this used to work, according to the googling I’ve done. Edge is capable of playing 5.1 audio, I actually do 5.1 broadcasts to Twitch quite often that I can play back in 5.1 from Edge. Can we get this working in Plex too?
