We've posted Procyon 1.7.3 PR2 in the Procyon support area--just right-click on it and "save link as...". Then open Procyon editor 1.7.2, select Utilities/Update Procyon OS, and navigate to & select the file you just downloaded.

This version preserves all the fixes of 1.7.2, and significantly reduces the audio artifact.

We'll continue to work on this, but will also produce a "full installation" version of this sometime in the coming week.

Thank you to everyone for their patience!
