popping noise
There is a popping noise that sometimes comes from my Late 2009 Macbook. If my volume is muted it goes away. It comes and goes whenever and the pops get louder sometimes. What is the fix?
MacBook, macOS 10.13

If you are sure the popping noise stops when the sound is muted, then either you have a bad speaker or some software audio could be glitching or sending the "popping" sounds to the speakers.
You could try an SMC reset and PRAM reset (hold PRAM reset for three chimes to make sure it activates several times).
Is this from the internal speakers? Does the same thing happen when using headphones?
The reason I ask whether you are absolutely certain the noise stops is because some hard drive failures can sound like a popping or crackling noise.
