Miscellaneous click and pops with delay block

Hello markscohen,

Do you have a system controller "talking" to the part?

I do not see any traffic on the Capture window so it does not look like you are sending communications using SigmaStudio. 

You listed that you are using Rev 4.6. I do not think that is the issue. What hardware are you using?

Feel free to upload your project.

Thank you, Dave, for your very quick response.

The only sense in which a controller is talking to the board, is that it is still connected to the USBi for adjustment and tuning. I’ll check to see if that’s the issue. However, I would no longer be able to track the artifacts in the real-time display in that case. Otherwise it is in completely standalone mode.

Following that thought, it’s notable that the problem disappears when the two oscillators are disabled (with their checkboxes).

I am using 4.6, but I do have 4.7 and can see if that makes a difference.

The hardware that I am using is this: https://www.walmart.com/ip/ADAU1401-ADAU1701-DSPmini-Learning-Board-Update-To-ADAU1401-Single-Chip-Audio-System/913999452?wmlspartner=wlpa&selectedSellerId=18988&adid=22222222227913999452_18988_149399659413_18555491263&wl0=&wl1=g&wl2=t&wl3=659831302554&wl4=pla-2080501691930&wl5=9030967&wl6=&wl7=&wl8=&wl9=pla&wl10=125210027&wl11=online&wl12=913999452_18988&veh=sem

I have found these boards to be pretty reliable, and the problem is limited to this program. Others that I am running on this board do not have the issue.

The code is attached already to my report, but if for some reason it’s not immediately readable, I can re-send it.
