No, I was having the same issue when the board was outside of the shell, sitting on a wooden table. I also used Kapton tape to prevent shorts. I wasn’t able to find the guide that you mentioned on the Boxy Pixel website. Do you know where I can find it? I’ll take a look just in case. EDIT: Nevermind about the guide, it’s here: https://www.boxypixel.com/pages/assembly...erry-pi-cm
I’ve tried setting the audio level in Alsa Mixer to 3% with the volume wheel set to high, and I’ve tried setting the Alsa volume to 80% with the volume wheel set to low. In both cases, the hissing and popping sounds were equally prominent.
I’m starting to worry that it may actually be faulty audio hardware at this point.
