Crackling Sound on Moto Z Play

[AC Question]

I bought a brand new Moto Z Play and after some days, I noticed a crackling sound (sometimes it's distorted) when hearing whatsapp voice messages. I cannot replicate this problem everytime because it is intermitent. I can hear the same voice message 10 times and it happens only once. On the worst cases, the voice message can distort as if its in slow tempo.

Does anyone have the same problem with Motorola/Lenovo phones? I owned a Moto G4 and had no complaints about it.

Any clues?

Thanks
