[Q] SGS I9000: sound crackles when start playing and stopping sound file topic

Hi,

I am using the cyanogenmod 11 (nightly, Android 4.4) on my old SGS I9000. It iswokring great, as KitKat can handle less memory quite well.

My only problem is an sound issue:

The sound crackles and rustles softly when playing a sound file with my music player (poweramp) or for instance a system sound.

It is like:
clicking sound playback > sound crackle > low rustle > sound playback starting > sound playback stopping > low rustle > sound crackle

(the low rustle seems during the whole playback period, but is been noticed by silence more)

Is anyone knowing the problem?

I have used another jellybean mod before > smae problem

problem seems not with the official latest firmware 2.3.4, but I don´t want to use this :)

Thanks for help!
