Hi! First post here.
During summer holidays of 2023 I decided to build my first project (Link). Everything worked perfectly, expect sound. It was cracking with some frequencies. It was driving me nuts becuase I thought I had screwed something up and since those holidays I tried five different amps, eight speakers, two displays, and two picos.
Today I found out that this project was flawed all along. I found a clip (Link at 3:20) that clearly shows the finished has this cracking sound.
Is there a chance to save this project? I've heard something about filters, but I'm not sure if that will solve the problem.
Thank you in advance for your help
