I have a DMX 6fire 24/96 and the sound quality is good but for some reason it doesn't play through the 5.1 speakers for mediaplayer and games that use it etc.
With my onboard soundcard mediaplayer and games play through the 5.1's but the DMX only plays through the front speakers. I've tried the usual of checking my media settings and it's got 5.1 selected (it works fine for the onboard card) etc.
I've been playing music through powerdvd which plays through the 5.1's as you can select your speaker setup on there.
I'm on XP home. The onboard sound is a Realtec AC97 I think.
