So I replaced my motherboard, GPU, and PSU last night. I just got done installing all the drivers and whatnot for them. My sound is really weird now. I have a new thing in my task tray called Realtek HD Audio Manager, which I guess came with my motherboard (Asus P5Q Pro).
The problem with my sound is, everything is really "echoy" sounding. Like when I play a game or watch a video, it sounds like the people are in a tunnel or something. Does anyone know what the problem could be, and how to fix it?
Yep, good call. That's what it was. After messing around for a while, I finally found where it was coming from. It had some environmental effects enabled, like you said. I disabled all sound effects, and now it seems to be normal again.
