Id like to capture the audio on my pms via ‘line in’ and broadcast it live to my plex clients
Interesting Idea, but this won’t work. Plex uses files that are in your library and not a direct input.
And just to say it, if you have a good turntable go get a good pre-amp and some good speakers. That’s way better than a stream that just “destroys” your good vinyl sound quality.
But when you really want to stream your vinyl then just add a Google Audio Chromecast.
Or if your turntable has USB you can rip your vinyls and add the files to your library, but I think that’s not what you wanted…
