Hi wakeskate,
I was curious to see what a Sabrent USB Audio Adaptor was (just in case you possessed a new form of audio alchemy that we all might be interested in...!).
It appears to convert USB audio output into 3.5mm headphone output.
The RPi does not emit an audible sound from the USB ports. It emits a digital stream of bits that need to be converted to analogue by a DAC. I wouldn't expect to hear anything.
Just trying to help...
