I am using window7 + creative sb x-fi hd usb + some sennheiser headphones and lately found that after install driver 1.2.21 over original 1.2.20 my sound got worsen (I usually playing flac files with foobar + sox resampler plugin + asio). After reinstall driver sound got back better quality.
I just wondering, i always do resample sound to highest profile what my card can play (24bit/96kHz) for bypass windows/driver resampling, and using even asio for bypass that but looks like that driver have own resampler and filters and even if i try best - driver can corrupt sound.
Know anyone a way to bypass driver and play original sound as much as possible?

Indeed, one of the selling points of the X-Fi line are their DSP capabilities - I've never used one, but given the marketing, I'd say there's a high chance that some of the sound processing features could be turned on by default. Upgrading your drivers could have caused some of the settings to be changed, that is - turned on or turned off, compared to what they were before. There should be an option to change all these things in Creative's settings somewhere. These are things like "concert hall" reverb presets etc., although they're probably called something fancier for the X-Fi line. For the highest level of fidelity to the source material, you'll want to turn all such DSPs off.

You could also try going to Creative's site and see if there's a changelog or bug reports or something for the new drivers. It depends on how good their documentation is, but I should think any large changes to the drivers that influence sound quality is noted somewhere.

My money is on there being a setting misconfigured, though. Probably something to do with either the DSP stuff or maybe resampling. Unfortunately I haven't used a Creative card in years and can't tell you where to access these settings... but I'd advise looking over them very carefully. The eye-candy GUI bloat on some of these manufacturer tools can make it difficult to tell what the settings actually are and what can be changed. (Controls designed to look like analog knobs, switches, and indicators, for example... yuck)
