Xubuntu 14.04.1 / LMS 7.8.1

I installed LMS 7.8.1 on my box running Xubuntu 14.04.1 (because of the perl version used by xubuntu 14.04) and it works fine--except it doesn't find/show/play any music files. I added my music folder under /home/[user]/Musik which is filled with subfolders and mp3s/flacs. I can navigate the folder and its subfolders in the web interface, so it can't be a permission issue. But LMS doesn't recognize/show any media files.

I suppose it's an issue with missing codecs/libraries. I had some similar issues with an older xubuntu version and serviio media server once.

Any suggestions?

EDIT: Fixed it myself--it was permissions after all.
