Um... I am using the "Clean Audio Folder" for the first time ever and after waiting for it to finish I played the first file and got a surprise... the audio is coming though Windows (Realtek) and not my Saffire.
I leave my Realtek online for Windows use only and the Saffire is primarily reserved for SONAR unless I manually change it (2 speaker systems), but this threw me for a loop. SONAR is open, but
no project is loaded into it (so the Saffire does not say "Locked" yet).
Edit: The CWAF tool has a checkbox on it for "Use direct sound" and "Primary sound driver" I guess this utility is getting long in the tooth.
Edit2: To add insult to injury here, I first used the CAF tool, which found 29 files in the global audio folder (carried forward from way back when) which I deleted. When running the CWAF tool, these same files (among others) were reported as "missing," so the tools apparently do not jive with each other either.
