I have had this computer for a while and use Zalmon 5.1 surround sound headphones. I moved my computer to my other house untel I can fix my other computer. I hooked my computer up to some Boston speakers and started to play some MP3s and noticed it sounds like its underwater and its crackly. What gives? I have had this computer for 3 years and never noticed it with my other stero and headphones. Should I get another sound card? If the sound seems so bad on Boston speakers I wonder what I been missing
