I recently bought a Macbook Air off of eBay,and it has no issues other than the left speaker making a popping sound ever minute or so,and I do not know how to fix it.

Hi You will need to get a closer look at things I would open it up and look at the speakers,check for any debris or metal shavings around the speaker and if the speaker looks clean try and clean both connector and board connector with isopropyl alcohol and reseating the speaker connector by following the guide that corresponds to what speaker you think has the issue MacBook Air 13" Early 2017 Right Speaker Replacement MacBook Air 13" Early 2017 Left Speaker Replacement If it doesn’t work you will need to replace the speaker that has the issue If you let me know what region you are from I can help get you some replacement speakers Hopefully this helps Any questions please ask Thanks:-)
