Default [Q] Hissing sound in earphones

I just received my G3 (the European 855 version) today and wanted to listen to some music from Google Play Music All Access. There is a terrible hiss/crackling sound, especially in the left ear and it's with earphones that (still) sounds fine on my old SGS3. I've tried with 3 different pairs of earphones and it's the same with all of them.

Does anybody else got problems with hissing/crackling sounds from the G3?

I solved this myself - the problem is "only" there if I'm using ART, after going back to Dalvik the problem is gone again.

Dont have this problem with my D855. Not with v10a or e. Used this phone with headphones/speakers about 8h/day since release.

Im using ART.

Switching back to Dalvik didn't solve it After a reboot the sound is fine but after a while the hiss starts, especially in the left ear. Nobody else got this problem? I'm on v10e with a D855 32GB

UPDATE: I just connected my Fiio and with that to amplify the sound the hiss goes away but as soon as I remove the Fiio the hiss is back again.

it's a problem.
But it depends what kind of earphones i use, with my sennheiser MOMENTUM it's perfect.

That seems to point to an impedance issue. It is not in every phone because I use very low impedance IEMs and do not hear it. I have also read reports of it just going away on its own.

This is a kitkat bug that was uncovered last year.

That doesn't explain why some G3 owners got the problem and others don't as we're all on 4.4.2

It's dependent upon the earphones you use.

Except that I have used a variety of different impedance earphones with mine and have never experienced any hiss. I think higher impedance can mask it if it is present but doesn't fix the root cause.
