Man I feel your pain.
Not sure what the other thread says in detail, but I have done something like this for shows. Its dangerous. The IDT is buggy as hell. There is a pretty cheap solution if you’re willing to spend a few bucks ($50?). Get one of those 5.1 sound blaster USB devices. It has an RCA channel for output and an 8th inch channel for rear speakers and sub. If you route it correctly then you can use your rear speaker output as the headphone jack. This gives you stereo on both outputs independent of each other and you don’t have to blow $200 on a traktor card. Whats surprising is the latency is really low if you use ASIO4ALL.
I use this at clubs. It actually runs quite nicely. Its pretty responsive and it puts out a surprising amount of power.
