- Sabrent USB
With the audio jack, I have no idea what is L/R in/out, but i do know the 2 left pins are connected on the multimeter and the 2 right pins are connected. I've assumed from this, and looking at the 3.5mm jack diagram, that the outer two are L/R out and inner two are L/R in.
Here is how I've wired this up. All i get is hissing/static noise once i plug the USB into my PC and play audio. I know audio is coming out, because ive left the green 3.5mm jack on the USB for now and it plays fine through that. Please help!
