Recording Issue when recording GRV6 via Rekordbox

Audio sounds fine live, but when listening to the recording it will become static and distorted.

In addition, sometimes the master output continues to play normally and the master level meter remains active, but the recording level meter next to the Record button suddenly drops to zero and the recording will go silent as if no audio is being detected. This will happen at a random point through out the recording and once it happens the audio will not come back.
