[Q] [GT-I9505] [Lollipop] Absolutely no media file plays topic

Hi everybody!

I recently updated to my phone to lollipop (using different roms but mainly AntaresOne's CM12-Build) and I can't play any media files from my phone. It doesn't matter, if it's mp3, 3gp, mp4, whatever. I tried sveral different players and approaches to play files but it simply doesn't work.

What can I do about that?
