FxSound does not detect Bluetooth headset after reconnect unless re-paired

When my Bluetooth headset reconnects to Windows after being in its case or battery depletion, Windows shows it as “Connected”, and audio works system-wide. However, FxSound does not detect the headset unless I fully remove and re-pair the device.

Steps to reproduce:

  1. Pair and connect a Bluetooth headset (e.g., earbuds).
  2. Use FxSound with it normally.
  3. Disconnect the headset (e.g., put in case or battery dies).
  4. Reconnect it — Windows shows “Connected”, and system sound works.
  5. FxSound does NOT show or apply enhancements to the Bluetooth device unless I unpair and re-pair it.

Expected behavior:
FxSound should auto-detect or allow manually selecting the Bluetooth device again after it reconnects.

Tried:

  • Restarting FxSound (sometimes works).
  • Manually changing the default audio output in Windows (still not detected by FxSound).
  • Updating all drivers.

Please fix or provide a workaround that avoids re-pairing every time.

Sorry about this. What happens when you cycle between some playback devices within FxSound and then go back to the bluetooth device?

Yes, I tried cycling between other playback devices in FxSound, but the Bluetooth device doesn’t appear in the list at all after reconnecting. So I can’t switch back to it manually.

The only workaround I’ve found is:

  • I run “Find and fix problems with Bluetooth devices” from Windows Troubleshooter.

  • After that, FxSound suddenly detects the Bluetooth headset again and it appears in the device list.

This happens consistently with any Bluetooth audio device — it’s not specific to one model.

So it seems FxSound isn’t picking up the reconnected Bluetooth device unless Windows forcibly reinitializes it via the troubleshooter.

@bvijay any ideas on what might be happening here?
