Re: Medium -> Low priority, sound problems.
Sounds like you may have your sound card setup incorrectly. Are you sure your sounds are playing through the correct speakers? Sometimes the sound can get messed up where it believes the front speakers are the rear speakers or it believes it has a center channel. If this is the case, the system will be trying to play sound (voices) through the center channel or front speakers and they are being faded out in the "rear" or not played very loudly if you lack a center. Does any of this sound like it could be the case? Check to see if your sound card is set to 5.1 mode if you only have 2 speakers.
