I've yet to narrow down the cause of the problem but occasionally I will try to play a MP3 encoded music file on the Music app and it returns an error of "Music player cannot play these types of files."
The file is 128bit 44100hz Mp3. Standard Mp3 file for all intents and purposes, and it happens on multiple MP3 files after this error.
Zimly will not play them either after this error. So it might not even be a Music app problem, but the MP3 lib file.
The solution to fixing the problem is pulling the battery and card. I don't want to have to keep doing this to fix the problem.
The best case scenario that I can come up with is I have it on silent mode when at work, which is where is happened. I might have had the media volume down while playing a game, but as stated previously I can't recreate it with those conditions. Next time is happens I'll try playing an OGG file to see if its all media files or just the MP3.
Anyone have any ideas?
