According to my googling an mpga file is simply an mp3 file with a different extension - standing for Moving Pictures Group Audio. In /etc/mime.types it is listed as "audio/mpeg mpga mpega mp2 mp3 m4a"
I can't find an "mpga" file anywhere to download though. Could someone verify whether or not this is still an issue? and if not leave a pointer directly to a .mpga file. -- Use smaller media player for OGG/MP3 files by default https://launchpad.net/bugs/12756 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
