i may be overlooking something very simple here but i just cant figure it out. on my old computer i used reaper all the time to record audio off of youtube for songs that i wanted to learn. i guess somehow i used the stereo mix that the sound card was getting as the input for reaper (internal sound card, no external cables, this is not a dedicated recording computer). now that i have a new computer, with windows 8, i cant get sound into reaper. i have the track armed for record, i have played around with the preferences a bit and have made sure that all my volumes are up on my sound card's mixer, but i still cant get sound into reaper... im not sure that reaper sees my soundcard. when i drag a wave file into reaper i can play it no problem.
