>             Project: Asterisk
>          Issue Type: Bug
>      Security Level: None
>          Components: Applications/app_mp3
>    Affects Versions: 18.6.0
>         Environment: Debian 11
> Tested with distribution packages for mpg123 and current version 1.29 
>            Reporter: Carlos Oliva
>            Assignee: Carlos Oliva

> Trying to reproduce MP3 files with MP3Player, we only hear noise on calls.
> We tested with 18.6 and older versions, and the problem remains the same when using Debian bullseye
> We discovered that actual versions of mpg123, using the same parameters that you use in your code, send more data than older versions. If you send the out data to a file, older versions creates files of half size than new versions.
> Parameters in our exection of MP3Player are:
> ["mpg123", "-q", "-s", "-b", "96", "-f", "8192", "--mono", "-r", "8000", "http://........"]
> Probably the parameters needed changed between old and actual versions of mpg123 to get the old behavior.
> We rolled back to ancient version 1.20.1 of MPG123 and everything works without need of patching asterisk, but I assume Asterisk should work with actual versions of mpg123.
