Recording an AVI: Can crackling audio be neutralized?

Hey, I have a question about recording AVIs from Snes9x 1.52, is there any way to get rid of the annoying audio crackling when playing back the AVI? When I load a ROM, the audio sounds perfectly fine (no crackling), but when I record an AVI (regardless of the codec used), it always crackles.
What can I do to get an AVI without audio crackling?

Current audio settings for Snes9x 1.52 -

Audio Driver: XAudio 2 (Direct Sound sounds like crap on Windows 7)
Sampling Frequency: 32000Hz
Latency: 16-128ms (tried all combinations in between)

What have you set as Input Rate? For avi recording this should be set to 32000.

Okay, right now I have it at 31850Hz, but as for the latency, I have it set at 194ms. Should it be 210 or less?

If you are referring to the buffer length: that setting has no effect on avi recording.

Oh

I didn't know that, but I adjusted the frequency to 32000Hz and the problem seems to have disappeared. As to why I wasn't aware of this before, or why I never noticed it making a difference, I'll never know. Thanks.

The avi recording should really do that automatically, I'll change that in the next version.
