[HELP] Nextel Chirp on Atrix 4G

[brobro]

I have downloaded the Nextel Chirp from the net in many different formats, all work when tested using either VLC or windows media player, however when I load them on the phone they don't have sound. Can either someone direct me to one that will work, or help by fixing this one for me. also if you can, let me know why this one wont.

SOUND.


Update: I figured it out, I downloaded a "ringtone" that was 10 seconds long that had the chirp at the beginning and another at the end of the file and edited it using the "Ringtone MP3" app.
