high pitch sound

Having a high pitch sound whenever playing a low bass type sound in Audacity. whenever I export to wav or Mp3 the high pitch sound is gone?
I’m guessing it’s the sound card but is there a fix?

What sort of “high pitch sound”?
Can you be more descriptive?

It shows up whenever there is DC offset? just a high pitch beep.

Have you tried removing DC offset with the Normalize effect?
