The 3.1 version of this ROM posted yesterday contained a CM13 bug, which prevented media playing.
A replacement version of the ROM also shown as 3.1 was posted several hours ago. This replacement version fixed the media issues and MX Player and Youtube now work.
Check that the kernel of the ROM you installed is shown in About Phone is shown as timed and dated Thur January 21 - 17.02.21 CET 2016.
If it is not that version. Download the ROM again and dirty flash it.Your media should now work.
