Craig, for several years I've used a Xitel HiFi Link to feed the digital output from the USB output of my laptop to analog stereo inputs of one of my receivers. I usually use this to listen to streaming classical music from stations all over the world. It's a bit pricey($40-$50)for what it is(besides the cables, just a simple DAC), but it does the job. Another unit, which I don't have personal experience with, is available from Turtle Beach .

Enjoy the music, not the equipment.
