Default [Q] AAC Streams on Galaxy

For some unknown reasons Galaxy S4 and S5 devices are unable to playback AAC Streams of audio (not files, streams). They connect and simply buffer the stream forever. No audio is ever played on device.

MP3 streams are working fine.

I'm looking for some way of contacting Samsung support(already tried level 1, I'm looking for people who work with their builds) to see if we can find out what's going on, does anyone know where I can find it?

Thank you.
