lost onboard sound

ive never really bothered with my onboard sound since I got a sound coard. The problem is that ive ot a program that requires two sound cards to be used. Ive check my BIOS an cant fin anything that enabled onboard sound.

Ive check the device manage also and there no yellow exclamation marks for drivers not installed properly.

my system details are

Never heard of a program that requires two sound devices. What is the program?

All I can see is.....conflict.

 

the programs a mp3 video mixing tool studio call virtual dj

 

Had a look at the manual & found this>

If your soundcard does not have two stereo outputs, another solution consists of using a second soundcard (for example an external USB soundcard in addition to your computers internal soundcard), and connecting the speakers one soundcard and the headphones on the other.....among other references.

Other than that all I can say is that the program looks like it has a steep learning curve. Hope you sort it out.
