AU-PM422 Audio Playthrough is crackling and slow. Bad. Headphone jack on Computer works fine.

UPDATE: Solved. Watch the Video: https://youtu.be/DNzwruJqVdo

I have the AU-PM422 Music played through it is crackling, slow, bad. I tried both a USB 2 and a USB 3 ports.

Same music through my computer headphone port is fine.

Mac Pro Desktop OS X 10.14.6 

And yes, the AU-PM422 is both an audio output and input device. :)

Will update when I hear back from Maono.

It is probably not the cable. Tried the original and a second I had laying around. Max data rate is 192kbps so I don't think that's it even if my cable was USB 1. :)
