There's a logmeindriver, procaster, My keyboards microphone port and my webcam.
Here's the output as well:
I use the internal sound from my Logitech keyboard for my Hackintosh,
It worked perfectly for several days before it started only putting out that hiss noise.
I have my audio interface that I record music with that I tried to get working only to get the same hiss, as well as two Airplay devices on my network, one of them not visible in the output screenshot.
