Apple MacBook USB Audio Issues
I ran into a strange issue on my MacBook Pro today. Turns out if you use the USB port closest to the LCD (left side of the MBP) audio tends to “skip”. Use the USB port that is furthest from the LCD (right side) and the audio works great.
Same thing goes for MacBooks, but they are both on the same side. Any USB audio device (headphones, external sound cards) should be plugged into the USB port furthest from the LCD.
