Hi,

Greetings from Norway, hope everyone is doing fine in these corona times!

I'm a musician working on a 13" Macbook Pro 2012 for music production, and for the past year or so I've experienced crackling noises on the audio input. Whenever I'm recording any sound through my external sound card (Steinberg UR44) there will from time to time occur crackling noises to the input signal, meaning the crackling exists on the audio file itself, ruining the take. This makes recording really hard. It do not occur on MIDI-recordings, only audio input.

I've tried different instrument cables, different instruments, USB-cables and external sound cards, and all I'm left with is the Macbook itself being the problem. The problem occur in both Ableton Live 10 and Logic Pro X, making me believe this might be a hardware problem.

I've scoured the internet for an answer, but all forums only address crackling to output signals. Input on this matter is warmly welcomed!

Specs:

13" Macbook Pro mid 2012
2,9 GHz Intel Core i7
16 GB 1600 MHz DDR3
Intel HD Graphics 4000 1536 MB
