I picked up the basic X-fi a few days ago to replace my onboard sound. Everything went fine for the install. Came home today and the sound was horrible. The msuic sounded like a ringtone from a cell phone. I dug through every possible setting, tried to ensure there were no conflicts, etc. I mean this couldn't be a driver problem, it worked fine two days ago.... After an hour or so I visited Creative's web site and found that new drivers had been released yeterday. I installed all available updates and magically the audio is now fine. Anybody else have problems like this?
