Having the PA volume control open, if I speak into the webcam mic regardless of the profile for the headphones, it registers that in the volume control, so I know the webcam mic is working. .
The volume control is not registering the mic in the headphones, however on the Input Devices tab, the sound card (Creative Sound Blaster Audigy Fx) is listed with 'Front Microphone (unplugged)', yet it is showing microphone activity. I have nothing but speakers plugged into it. Could the sound card be causing it or be defective, or perhaps PulseAudio isn't detecting it correctly? I have muted that particular entry.
Also, with the headphones using HSP/HFP, the webcam mic doesn't work on the test sites. But after switching the profile to A2DP Sink, the mic then works on the test sites. This may have to be a workaround.
I am not sure if I understand correctly your setup.
Headphones are not to be used with HSP/HFP if they do not have a mic (if they are not a headset). In the case it is only headphones you should use A2DP with Sync (bluetooth)
The Mic of your webcam would be then a Source. You need pulseaudio-module-bluetooth installed (check). You need pulseaudio set correctly
Check pacmd list-sink-inputs pacmd list-source-outputs
might be you have to set input/output manually
