I have this extension enabled and working for Ogg files but I can't get it to work for FLAC files. As per the documentation, I added $wgMediaAudioTypes = array( 'Vorbis', 'Speex', 'FLAC' ); to my LocalSettings.php file and ran update.php. Still, no FLAC. To double check that what I'm trying to accomplish is possible, I embedded a FLAC file in a sandbox article on WP and it worked as expected. I'm running the same version of the extension as WP and version 1.21.3 of MW. So, I realized that I must not have something enabled/configured correctly but now I'm at a loss for what to do next. Here's an example of an attempt to embed a FLAC file on my wiki: http://preservapedia.org/Bruce_Sharky_discusses_the_use_of_wikis_in_graduate_level_coursework
Any advice would be appreciated.
