I faced this annoying problem where earphones made crackling sound randomly while playing music only while screen was off.
I saw another thread where people faced same problem in S III, but no definite solution.

FIX :

You need to be rooted.
Just change your CPU governer to "On Demand".

Mine was set to 'pegasusq'. I believe it forces CPU into low power mode while the screen is off and CPU frequency becomes so low that read speed of music files reduced.

Above FIX resolved my issue. I wanted to share so that anyone suffering from same issue can be benifited.

Work-around

If you want to use the same CPU governer(as it has good performance), you can set the minimum CPU freq to say 400.

If you are rooted, then just download any CPU monitoring app. I personally use Rom Toolbox. In CPU/Processor settings in the app, you will find "Governer" and a list of available governers to choose from. Let me know if you still have trouble finding it.

TIP : Don't set Governer to "Powersave" even for trying it out. You wil find your fone lagging extremely.
Also don't play around much with other CPU settings unless you are absolutely sure what are you doing.

There actually isn't a need for changing the whole governor.
Download trickster mod from google play and in that change hotplug_min_CPU_lock to 2 whenever you want to listen to music, and change it back to 0 afterwards. Ondemand causes lags under heavy load and can be a battery drainer too. Pegasusq is multicore aware and can scale the cores depending on load and hotplug threshold defined by min wake CPU frequency or run queue length, and thus is more liberal on battery too, while providing a good performance at same time.

I can only find min_cpu_lock NOT hotpug_min_CPU_lock, is this the same thing?

Nice trick :thumbup:

I just change to Ondemand Governer while listening music then back to Pegasusq.

But got to admit, it's a very annoying thing.

Hello, I am using agni kernel. I don't find ondemand governer in this latest version. Any workaround for this? I am really worried about the freaky noise that I get while listening to my favorite music.
Awaiting help.

Thanks,
Sukumar

Well that really works and I still can't figure out what caused the issue. I was in resurrection remix 5.7.4 with no agni and it was doing all good.. I am now in Eclipse v9 with agni kernel set to all default except the touch wake. I am seeing no such problem any more.

May be Kernel is what that is making that freaky noise..
Thanks for the suggestion.

    Did you find any fix for this? I have a work around.. When I apply pressure at the top left corner of the phone, it sounds. I think, it is possibly the issue with connector or the jack itself.. I have ordered for a replacement from DX.com.. Waiting for it to arrive. I will install the spare part and let you know if it worked..
