I have set up a fresh Moodle 2.6.5 and installed Poodll filter, online submission and the TinyMce plugin. I can record on a forum thread from an android phone using a MP3 recorder, using the phone's recorder but the upload has no extension.
If I download and edit a .mp3 extension on to the bare file it plays. Have I missed a setting somewhere?
No, thats a bug. Sorry. I became aware of that this week. I will fix it this weekend. Should be ok by Monday.
I have made some changes. So when you get a chance please try again, and if possible report back
