Music on Hold Choppy from Mp3 only

I installed an asterisk-freepbx system and the users hated the default on hold music in fact everyone does. :stuck_out_tongue:
(I don’t understand why people complain about a free lunch)

Anyway I’ve uploaded a couple mp3 files to play as music all free use stuff. The music is choppy sometimes with the mp3 files I try and use. the default music works fine. I’ve tried different files but always get the same thing.

I thought it was a bandwidth and CPU issue, but both seam to be more than enough so I am thinking its something else.

Is this an audio quality issue or a configuration issue?

Do I need to redo the sample rate of the mp3 files?

What things could I check or do to solve this issue?

Any ideas or suggestions would be helpful!
Thank You
