When I start Plex for Windows and click the cast icon on top, the only player found is “Plex for Android” running on my Galaxy S22 Ultra.
None of the 12 WiiM Pro Plus devices are found.
Neither are the 2 Chromecast Audio, 1 Chromecast Ultra, and 2 Chromecast with Google TV.
Neither are the 3 Marantz receivers (NR1603, SR7011 and SR8015).
Neither are any of the software DLNA renderers (BubbleUPNP, JRiver).
Neither are the 3 Fire Stick 4K.
Neither is Sony UBP-X800 Blu-ray player.
Even if I select audio or video and try to play it, the player list remains the same in the Plex for Windows desktop app.
If I use Chrome on the same Windows computer, and use the More / Save and share / Cast menu option, the device list includes all the WiiM, Chromecast, Chromecast groups, Fire sticks, and Blu-ray player.
On the other hand, the Android app lists all the WiiM and Chromecast players, including groups, do show up in the list. The Marantz, BubbleUPNP and JRiver players still don’t show.
FYI, all devices are - phone, desktop, stickss are in the same /24 IP network. Nearly all of them are wired using Ethernet, except the phone. A good chunk are hooked up to meshed Wifi APs via Ethernet. PMF are disabled on the Wifi side.
