I have an mp3 File hosted on amazon s3. It plays when i open the URL in safari, but doesn't in chrome.
Here's an example: https://s3.eu-central-1.amazonaws.com/media.radio32.seerow.ch/songs/2017-08-03/04%3A10%3A24/2228490.mp3
Found the solution. The File I got was encoded with an old MPEG standard (Layer 2 instead of Layer3).
