I had crackling in my M1 MBP headphone jack, any variety of plugged in, USB/DAC all summer/early fall. I assumed it was an audio controller issue. And then it kind of dissipated, until there was a warm day in October. I had just watered the plant on my desk. All winter -- not an issue. House is cool and dry, but as soon as the humidity gets above 60% or so, I get crackling. Not sure what I'm going to do this summer.
