I said earlier I was wondering what quality of sound I could expect from the preamp on my mobo. Well, I watched a movie yesterday and used SMPlayer. Gee, after setting the sound, max volume, enhanced stereo, and surround sound -- yes with headphones! -- I really had the impression of standing right in the middle of the scene. I could have turned the volume so high my eardrums would have blown out! So, the preamp is not the problem.

Where do I make these adjustments for general use, when I'm listening to Flash or WMV, for instance?
