Looking for "recent" stuff from EA

I am currently trying to decode the EALayer3 audio codec (its derived from MP3 audio and is widely used all over EA) as well as a few other audio codecs used by EA. To that end, I am looking for any of the following should it exist out there somewhere: (I doubt any of this stuff exists outside of EA but if it does, I suspect the sort of people who hang out here are the most likely sort of people to have come across such things)
1.Any source code for any recent EA games that contains (or may contain) audio code (and may contain things that help with the audio codecs I am reverse engineering)
2.Any EA tools related to audio that are out there (those might contain things that will help with the audio codecs I am working with)
3.Any builds of any recent EA games that have debug information (e.g. PDB files, things like that)
4.Anything else at all that may shed light on EALayer3

Oh and before anyone points me to https://bitbucket.org/Zenchreal/ealayer3 I already know about that code but have established (via reverse engineering of a server executable and matching PDB for Battlefield 3) that there are still a bunch of things in the format that we just dont know yet, hence hoping there is something out there that might shed just that much more light on this most mysterious of audio formats
