sorry been that long since i've used a windows operating system and having a brain dead day so can't think of anything else to suggest at the moment, except maybe try a 3rd party player like vlc :- http://www.videolan....ad-windows.html
and see if you can use it's settings to adjust audio properties with that.
ok while i've been searching i see nev made a post, so please don't forget to answer his question a new driver may be the answer to your problems.
until then read this guide and see if it helps you setup your sound correctly so it shows bass settings and such so you can then adjust them. :- http://www.sevenforu...indows-7-a.html
We are still in "Tier Four" when we click one of these icons listed in this tab. We get to Tier Five by a different route (be patient). Tier Four however allows us to get at some special settings that Windows provides via its "default" driver mechanism. It allows us to specify whether our speakers have a woofer or multiple satellites (2.1, 5.1, etc). Also it defines whether or not full-range speakers are in use. If you change this here, then the "enhancements" provided by Tier Five will subtly change and this can dramatically affect the sound quality achievable - very important if you like your bass to be either bassy or burpy.
