Headphones have no sound

[DjFrankB]

greetings... i use mac.... want to broadcast with traktor pro2.... i adjust my dj equipment and sound is great broadcasting.... my problem is that once i adjust my equip. to broadcast, the ASIO changes and i get no sound in my headphones connected to my mixer.... this is for obvious reasons.... how can i direct the sound to broadcast and to my headphones? i have been trying to resolve this for a few looong days now... its not traktor....
