Ok, this is really weird. Randomly, my music or whatever was coming out of my speakers began sounding warped or muffled. It had like a weird echo or something. Anyways, I couldn't get rid of it by restarting programs. I finally got something to work by opening the sound preferences and changing the audio profile under the hardware tab. Why the sound started and why the "fix" worked, I have no idea?!
edit: This was happening on my laptop only.
