Hi, I also had issues with my wireless HS-W1 microphone not working, in the audio settings it was listed but apparently no input was coming out of it.
I installed pavucontrol and fixed the issue, in particular, in pavucontrol both the internal mic of my desktop machine and the wireless one were listed (in audio settings only the wireless), and there I could disable the internal one, set the wireless as fallback, and voil, I now have the mic working. Hopefully it will help others.
