Distorsion problem with Creative EQ

Hi,

I have a problem with the Creative Console EQ, I don't know if it's fixable or not (is the EQ software or hardware on these cards?).

Basically, I have enormous distortion with certain sounds in the 30 - 125 hz range. When this happens I get some sort of "frrzzzz" (sorry, I'm french and don't really know the correct english word for that) on top of the original sound.

I have a Sound Blaster Audigy SE. I'm using the Daniel_K drivers, on Windows 7 Profesionnal x64. All the effects are disabled except EQ.

Steps to reproduce

- Put the card in 24bit/96khz mode. The problem is also present with 16bit/48khz but seems to be less audible.
- In the Creative Console, use the following EQ:

- Play this sound at a reasonably high volume. You should hear distortion on the two "booms". Especially the second one.
- Disable Creative EQ.
- Play the sound in an application with an integrated EQ (e.g. foobar2000, ffdshow) using the same EQ parameters. There is no distortion.
- Conclusion: the Creative EQ is broken.

Is anyone having the same problem? I'm also interested in the results with other Creative cards or even other brands soundcards with a similar EQ feature.

Questions:
Is the source material 44.1/16?
Have you tried the card in 44.1/16 mode (if there is such a mode)?

No, it's 48/16.

I just did, here is the procedure I followed:

- Resampled problem.wav to 44.1/16
- Put the card in 44.1/16 mode
- In the sound card properties of the control panel, switch the shared mode to 44.1/16

The distortion is less audible than with 96/24, but it's still here. Same as 48/16, in fact.
