Issue: DLNA renderer (WiiM Pro) intermittently disappears from Symfonium cast screen. Sometimes reappears after WiiM reboot, then disappears again after hours. BubbleUPnP sees the WiiM Pro at all times, so the issue seems specific to Symfonium and/or Redmi MIUI.
Network setup:
Fizz router (Hitron CODA), UPnP enabled
Separate SSIDs for 2.4 GHz and 5 GHz (Band Steering disabled)
Phone and WiiM both on same 5 GHz network, confirmed same subnet (192.168.0.x)
Already tried:
Battery optimization disabled for Symfonium
Allowed all permissions in app settings
IPv6 disabled on WiiM
Static IP set on WiiM
Band Steering disabled, SSIDs separated
Factory reset WiiM Pro
Wi-Fi toggle on phone (off/on)
Force stop + clear cache Symfonium
Cleanup internal states in Symfonium Advanced settings
Reboot and reinstall
BubbleUPnP consistently finds the WiiM Pro as a DLNA renderer while Symfonium does not.
I don’t know any other way. Bubble probably always run in the background and listen to events that the devices maybe send like every X minutes as some do.
@Tolriq I’m having a very similar issue. I’ve uploaded logs as “bigmack3000”. One small and one large (sorry).
When I check the wiim app, it sees and is connected to wiim pro, but in synfonium, it can’t be found. Occasionally, it finds the chromecast for it, but not upnp.
The small log is just there incase you can see why the unpnp isn’t being found. Its just me opening the app and checking casting options. The reason I included the much larger log is because after one restart attempt of the wiim pro, symfonium finally picked it up. I played music for awhile, but then the upnp option disappeared from the list again:
However, it continued to stay connected and play music. I then stopped the current playlist, incase it was just cache, played a brand new song. It continued to work as if it was connected. Despite not being an option under casting:
