You need something like this

Connect it to the CD/DVD input on the Philips.

Maybe is blasphamy for me to contradict americanaudiophile but your Phillips doesn't have the required Digital Input, nor 6 discreet amplifier inputs for this box to work.

Your initial setup SHOULD work, but I wager you have the wrong cable. I mean this thing suppose to be standard. You have a 3-collar (very important) 3.5mm on one end and 2 RCA plugs on the other correct? and this laptop works with with any third-party earphones yes?

You say your DSP has a USB input. Therefore, it accepts digital signals. Why don't you use that? The sound quality will be far better than through any laptop DAC.

I am always ready to hear from blasphemers. Gotta learn from someone.
Not much info on the Philips online but he says the CD/DVD input has 5.1 RCA inputs.
The USB input is usually for a storage drive and won't work as a USB DAC.
If you use the stereo output of the laptop you would need to have an analog surround sound mode on the Philips. Not as good but it will give you some surround. Try any that it has.
