Static on USB Out
-
I'm using the USB interface to record output audio from my spark, but there's some underlying static. This is regardless of the noise gate and subsists even when I turn it on. It's sort of a quiet static and is not jarring but I would still like to not have it. I also do have a grounded supply. Thanks.
Extra info
I tried plugging my headphones directly into the audio out and the static is still there. I for some reason, it seems that when I turn up the music volume knob, the static increases. This is even when I have nothing plugged into the amp and when I plugged the USB and something in the audio in jack. If anybody has encountered this before, I would love to hear your experience. Thanks.
