Above information is good.
A couple of other things, in DSP Studio, Output Format see if the checkmark is on. Try it both ways. If that doesn't work, try matching the channels to your speaker configuration. Stereo will still play stereo.
The other thing is output encoding. Some wetups can't convert certain sample rates (88,200 Hz for instance or those that are too high). Try changing the 88,200 to 44,100 or 96,000.
Try output encoding to None or Dolby Digital.
There's a sweet spot somewhere. You just have to find it. Do it step by step, one thing at a time.
Good luck
