Reply to Vestax Typhoon Controller/Headphone issues

Hey everyone,

I just bought a Vestax Typhoon with the traktor LE bundle.

Everything has been working just fine with the output to the amp. However, I can't get the headphones input to work.

Anytime I hit the headphone button, nothing plays in the headphone. I've got the output mixing to INTERNAL.

I get sound through my headphones when it's set to EXTERNAL.

Anyone have any idea of what it could be?
