Hmm odd, because 1.6 is meant to improve phase sync stability on the Pi 4, and it does on my Pi4's at least.

Are you running any other programs on the Pi4? Anything interesting about your setup?

Oh and double check your FIR and decimation settings. The new version now has a community update which remembers the previously set settings in between runs. So maybe you're accidentally running it with the FIR and decimation settings turned on, when they should be off for calibration.

Actually now it works.
for synchronization after checking the noise source I did update which removed the noise source.

thank you so much

I tried 1.6 during some testing this week and found for some reason I just could not get it to sync as easy or if I recall, at all. Ended up rolling back a version for now. I did notice that when you check the enable sync and noise boxes that if you also hit update it automatically unchecks the noise box, not sure if that’s intended. Seems okay if you just check the boxes and do not hit update.
