How can I make Alexa detect my PC Plex Media Player



Hi have a PC that runs Plex Media Player app (it's the same PC that has Plex Media Server on it). I can detect my Roku 4 but I can't detect the Media Player nor the Chromecast.
I am using Windows 10 and I am connected to my projector via HDMI (it's not streamed).

Should the Media Player be opened on the PC in order or that doesn't make a difference?


So I do not believe the chromecast is a supported device for Alexa.

Yes you need to have the App opened on the device you want it to control.
