Issue description:

Symfonium 14.0.0 / Android 13 (TKQ1.221013.002) / Redmi MIUI 14.0.9 / WiiM Pro (4.8.805729)

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.

Nothing answers back to the multicast discovery. Not sure how Bubble can still find the device.

Could this be that BubbleUPnP uses a different discovery method?

This tells me this is probably a MIUI 14 issue, I need to try with another android phone to find out.

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.
