Rapid audio pop static noise when no sound is being played

[drprez]

I have a D 32 using the DAC going to an amplifier out to my speaker when I have a power switch in between to turn the speaker on and off when the speakers off I don’t have any audio feedback or popping noise when I turn it on. It is constant rapid succession of a pop noise. I put a capacitor between the two leads that did not solve it. I’m trying to figure out how to eliminate this sound. I fix parallel lines on my PCB didn’t solve it. I’m using a 3 W speaker with 5 V going to it on a separate power supply..


I also have a stereo mini audio jack going out which does not have the same problem that is clean. It’s only going to go to the speaker through the digital potentiometer that I have this problem.

Here is a link to a video of the noise it is making
