I shall completely second this easy fix. I have 6 galaxy s6 for staff and everyone of them within a month had the distortion. Now with sucking on the speaker at the bottom of the phones, they all sound as they should do and back to normal. Go figure!

I literally created an account to verify this. Crackling was very irritating and this fixed it instantly

This really does work! I literally tried everything else and figured what the hell. I'm a bit of a germophone though so instead of sucking on the speaker with my lips I used a disposable liquid medicine syringe with a press in bottle adapter. Worked instantly on the first try! So happy I found this thread and avoided going through an entire warranty process for garbled speaker issues. No idea why this fixes it but it works!!!

DId your issue sound like it was skipping/stuttering and was that a fix?

Just go to your settings, systems, storage, then clear (delete) cached data. Instant fix.

I fixed mine 100% by simply turning the volume up full wait a second or two then back down to the desired volume. QED, fixed. Nothing else worked.

Finally fixed!!!
This is for those who are still facing the issue even after trying all the things mentioned in this thread.
After three days of struggle and multiple resets and settings change, I managed to fix the cracking sound by changing the Sound equalizer to POP from NORMAL. So just keep changing and hope it works for you all.
And still no one knows why are we facing this weird issue!!!

This crackling sound has been happening on my phone for about 6 months. I've had the phone for 2 years. Every time it happens I figure it will blow up my phone... Today I sat down and scoured everything I could find on Google. Nothing I found worked. Desperate I thought to try opening the app with the icon versus the home button (turn option off in camera settings. I cannot get it to crackle! Even changing from from to rear camera has stopped crackling. How crazy is if that's the fix. Anyone have the crackle that turned off the home screen open and uses the icon only?
