The way I got it set up with my Q10 is:
(and first of all, I play everything basically through windows media player if it's a .wav or .mp3 ...you know like somebody will send it to me over the net and thats where it plays. With the Q10, it takes a good 5 seconds before it plays, and the whole computer hangs for that 5 seconds while it gets ready to play it through the Q10.).
So, this really pissed me off ofcourse. ha.
I ran a stereo out from my speaker/lineout on the motherboard soundcard, and took 2 1/4" monos from that (after an adapter of course) to my Q10's 7/8 IN on the front. That way it will play instantly, through the headphones/monitors/whatever is hooked up through the Q10.
I know I'm possibly (or AM) losing a lot of quality like this, but it's just for ease of use...and honestly I can't tell. I don't monitor or mix anything recording-wise through that...all of that is on Vegas ASIO. So, it's really a pretty good fix for the infamous Q10 and windows' low sample rate/whatever problems. ha
