Summary:                    native asterisk format moh playback sounds garbled
Description: 
I have several .mp3 files in /var/lib/asterisk/moh/
I have removed the stock .wav files
During moh playback these files always sound garbled.
I get warnings in CLI during each playback

[Jun  9 12:05:35] WARNING[28610]: mp3/interface.c:215 decodeMP3: Junk at
the beginning of frame 49443302

This has been happening on various Asterisk 1.4 versions for a long time. 
I thought it was time I opened a bug report...

Playback using madplay sounds perfect, but I would prefer to use Asterisk
and sound converter to avoid CPU usage and transcoding.
I get the same garble if I convert the mp3 files to other formats using
Asterisk and put those files in same directory.

I'm confused, are you saying you are only getting this garbled sound when
using the mp3-to-native conversions when using mpg123?

Why can't you convert the mp3 to ulaw (etc...) with sox or something, then
just let Asterisk play the ulaw file directly instead of having to convert
each time? Does that still sound garbled?

I'm actually going to close out this issue for now as I'm not sure there
is really anything we can do here since Asterisk is just using external
applications to do the mp3 conversion.

Thanks!
