I've got 3 soundcards and none of them make me happy.
Onboard Epia M10000 - never tried it.
First I got the Sonica Theater, worked great, but when I come out of hibernation, its not recognized by Windows and I have to physically unplug the USB cable and re-connect for it to work.
Then I picked up the Audigy NX, works great, but lacking some features that the Sonica had: Support for 4.1 audio and crossover selection for each speaker pair. But the kicker, I could no longer play DVDs, it took up too much USB bandwidth and my USB DVD drive. I was OK with it for a while, but it kept bugging me, so I looked for another solution.
Then I went out and bought the Philips Aurillium PSC805 USB sound card. Got busy on a job before I had a chance to test it, next thing I know I'm out in Philadelphia shooting the Eagles/Panthers game for an HD camera test while my 14 day return period expired (Comp-USA). So now I'm stuck with this card also, which is similar to the NX as far as dissapointment, no DVD playback.
Now, I was looking at the Extigy and noticed that it is only USB 1.1, like the Sonica Theater. The Audigy NX and the Philips Aurillium are both USB 2.0. Before I go out and buy a 4th sound card, I ask you if you think it is possible the Extigy will solve my problems because its only USB 1.1?
