Default [Q] Custom Rom Audio Codecs?

First time custom ROM flasher here,

I am running the Google Edition 4.4.2 ROM by danvdh for the T-Mobile Galaxy S4 (SGH-M919)
ROM thread here: http://forum.xda-developers.com/show....php?t=2539361

I have noticed now that I am running this ROM I cannot play WMA audio files. I've never heard of audio codecs for mobile phones, but if this same issue were occurring on my PC, it would be the first thing to come to mind.

Do I need to install some codecs? If so, which codec packages do people recommend?

Thanks in advance for any responses.
