PipeWireAudioCaptureApplication not working with Bluetooth headset

I'm running OBS 31.1.2 (64-bit) on openSUSE Tumbleweed (20250818), and have run into a weird issue that I can't figure out.

I'm using the Source Record plugin to capture a few input sources, and set up the PipeWireAudioCaptureApplication source. When I'm using my bluetooth headset, I see audio in the audio mixer, but when the Bluetooth headset switches to the HandsFree profile, then the application audio stops being captured (the mixer indicator goes dead, and recorded video from that source also goes dead).

I am using the BT headset's microphone to record audio with a camera being driven by the DroidCamOBS source (I get cleaner audio with the BT headset than I do with the mic on the camera, so I prefer using the BT mic instead).

Why does changing my system audio output device is affect the PipeWireAudioCaptureApplication source?

Thanks for any insights.
