I have a 5.1 channel amplifier (Lasonic DBX-510) just laying around and I figure maybe I could hook it up to my PC. The amp. have a 9-pin DIN input and uses a 9-pin DIN to 6 RCA cable and connects to a DVD with a 5.1 (6 total) RCA out put. I have no idea if this would work though. I'll use three 3.5mm to dual RCA adapter. 1 for both front-left and right, another for rear-left and right. Though I don't know if it work for the center and sub. Any feedback or other method? Thanks for your time.

Hi, Not sure that your going to get the effect your after with out a 5.1 sound card in your box, but if you have all the gear "lying around" give it a go I say. Oz "Bite off more than you can chew, And chew like hell!" Peter Brock.

I'd say definately get a 5.1 soundcard w/ a digital output. If it's a Dolby Digital 5.1 amp, it should have digital inputs (sp/dif [coaxial] &/or toslink [optical]). I have a little Mini-ITX box mounted in my home theater for use as a divx/xvid player. Gets wireless 'net and outputs to a progressive TV (s-video, analog) & a DD5.1 receiver (sp/dif).
