.2 sec. of noise added at start when exporting file as AIFF

more often than not, when I export a file as an AIFF, I get ~ .2 sec. of ‘pfft’ noise at the beginning of the AIFF. my fix is to start a new file, import the AIFF, remove the noise, and export the file again - it’s always fine. kind of a pain, wondering if there’s a fix? thanks in advance for any ideas.

Exporting as AIFF should give you a virtually exact copy, and does on my machine.
Can you give exact steps for me to recreate the problem?
