Headphone pre cue timing is off

Listening to music in the headphones for pre cueing is completely out of sync with the main output. There seems to be a delay in the music playing though the headphones.

Hardware = rane one
iPad Air 2020
iOS Djay v3.7.6

Main output = ch1/ch2 on the rane one
Headphone output = ch3/ch4 on the rane one

I’ve found the issue. It’s not the line out for the headphones. The speaker I was using for the main line out has latency. Post can be closed :blush:
