I did the same test (listening to music on earphones) using another ROM (Ressurection Remix) and the results were the same.

Crackling sound when entering a subway station with poor 3G signal...

Maybe it's a hardware problem.

Please Xiaomi fix this BUG. For everything I have read in places and forums the probable reason that causes this is BUG is the mobile network signal interference.

I think I fix 60% of this bug with this tutorial: http://en.miui.com/thread-518811-1-1.html

I created the thread below and there are lots of people that have the same problem.
http://en.miui.com/thread-494758-1-1.html

I was able to reproduce the crackling multiple times.

First, I was listening to music on earphones and I notice the crackling as soon as I entered a subway station where the 4G signal is not good.

When I was inside the train the crackling continued and I switched to Airplane mode. The crackling stopped.

Then I tried switching back to normal mode and the signal was still weak (3G instead of 4G) the crackling sound appeared again.

After that I tried disabling only the Mobile Data instead of Airplane Mode. The crackling stopped again.

After getting home with a good 4G signal, I couldn't reproduce the crackling behavior by switching Mobile Data on/off.

Then, I switched the "Preferred network"  to 3G to force 3G signal and tested switching Mobile Data on/off again. I could hear the crackling sound again!

Now I can reproduce as many time as I want.
Just force 3G network and switch Data Plan on/off.

So... Apparently the problem occurs when the signal is weak/lost and the cell phone is "searching" for the signal.

I hope this helps developers analysing/solving the problem.

Si, acabo de recibir el Redmi 4 pro y sucede lo mismo. Se distorsiona mucho el sonido en música y audios en altavoz principalmente.
