Crackling sound coming from speakers on Galaxy S7!

[Android Central Question]

My phone just today started making this weird crackling sound whenever I turn the volume up or down. Someone help? NFC is off btw

Does it do the sound just when you change the volume? Or at all times? Is it just during calls or with any sound? Might be that the speaker membrane is damaged, which would cause a crackling sound.
