In terms of serious Mac audio issues, when I got my new M1 MBP I quickly noticed a faint crackling sound (unaffected by the volume setting) in the headphone jack when plugged in via MagSafe or a left side USB port. So I just have it plugged in to power on the right side instead.
Other people have reported it too, so it's not just a one-off defect. I know electrical engineering is hard, but it's a really annoying problem to exist on a super expensive laptop.
- aeonik 3y agoDoes your charger have three prongs or two? Try grounding the laptop properly with three prongs.
- diebeforei485 3y agoM1 MBP's only come with two prong chargers, except in markets that use the British plug. Depending on the cause of the issue grounding could help, but you'd have to buy an extension cord with a ground.

- matt-attack 3y agoEver seen a short version without a cord? Similar to the standard two prong attachment? Edit: https://a.co/d/6yvKXPW https://a.co/d/6yvKXPW
- plussed_reader 3y agoYes, I have a few 'san francisco special' ungrounded power tails but to my knowledge they were only made during the PowerPC era and did not continue into the Intel era. e. oh grounded short adapters. I wouldn't go for that due to the wall wort issue. I usually swapped out my apple bricks to grounded tails because it was usually easier to work into whateve ad-hoc power I encountered.
- aeonik 3y agoI'm aware, I have two M1s, but I had a static issue on my wired headphones at one point, and I fixed it with proper grounding. Though I can't remember if it was my old Intel Mac, or one if the newer M1s. I haven't used the wired headphones lately. I'll see if I can find them and report back here.
- viraptor 3y agoHaven't noticed it affecting the audio, but you can definitely feel the grounding issue when touching the back of a charging MBP. You get a tingling / bumpy surface sensation. I've seen people complaining about getting actual shocks for it though.
