Custom ringtones don't work on Cyanogenmod 9 I'm running Cyanogenmod 9 on my S3, and want to set an mp3 file as the ringtone. As this wiki page suggests, I've created the directory '/sdcard/media/ringtones` and put the sound files in there.

Just to be sure, I put both an mp3 file and an ogg file (of different songs) there. They're world-readable. The ogg file does not show up in the "choose ringtone" dialogue. The mp3 file does show up. However, when I choose it, there's no preview sound, as there is with the other ringtones that came with CM9.

What could I be doing wrong?
Before you wipe your phone, consider using a free app like Ringdroid to assign contacts with specific ringtones or even to just make a custom ringtone out of an mp3 track of choice.
