I have an audio program for my soundcard ("Avance Sound Manager") you may
have a different one, but I know within there, I can add echoes, make the
sound as if it were in a bathroom, make it sound as if I was
underwater...etc...etc. If you have a similar program, or don't know,
contact your OEM (if you have one, as they would know better where to tell
you to go to fix the problem.) Hope this helps.
