hercules dj control air - virtual dj

hi guys,

i use virtual dj for my hercules dj control air because i think it is a better program than djuced but i have a problem: i hear the music only trough the headphones, the speakers dont work...

my sound setup:

input: none
output: headphones, master chan 1/2, headphones chan 3/4
sound card: asio driver, hercules dj control air asio

if i change the output to master chan 3/4, headphones chan 1/2, i only hear music from the speakers...

can anyone help me please?
