Hello, I have an Creative X-Fi Titanium HD PCIe card, Windows 7 x64 sp1 and a Sennheiser HD 650 headphones. Yesterday I was curious to find out if there is a difference with the PAX drivers: IT WAS, but not a positive one. Let me be more specific. With the PAX drivers I detected the following issues: - the sound is clogged - there are constant cracklings - the bass and treble are, actually, as advertised (but for me are worse) - OVERALL the sound is WORSE OK. I've switched back to creative drivers and SURPRISE: there was no change. The sound was exactly the same (like the sound with PAX drivers). I even reinstalled Windows and the problem still persist. My conclusion is that the PAX drivers modified some IN-CARD settings. You have any idea how to reset the card?
