yeah what guino said. I was forced to use the cd line in on my mII12k but i use an audigy2 notebook card for sound output. I use the line in plugin for winamp, then tell roadrunner to use it. It took me a bit when i got my HQCT to figure it out, but it outputs on all speakers and sounds just fine(minus the slightly static fm when I leave the city....)
Btw. I tested the new rrhqct and it tends to pop up in front of roadrunner now for a few seconds before it minimizes. the old one never popped up at all just automatically minimized. its not that big of a deal, just thought id mention it.
