Popping / cracking sound when voice recording on my LG v10

Hi, everytime i record using whatsapp, snapchat, or easy voice recorder on my T-Mobile LG v10 , there is a popping / cracking sound at the beginning of the recording when i replay it. This doesn't happen on my stock camera app and voice recorder app. I am on version 6.0 and this has been happening to me on Lollipop too . i am not rooted and no custom rom. Does anyone else have this issue? If so, how can I fix it? Please help, you're time will be very appreciated
