My extension looks like this:
exten => 1006,1,MP3Player,

When I try this extension, the following output appears in the CLI:
Nov 13 12:47:51 NOTICE[8422]: app_mp3.c:111 timed_read: Poll timed out/errored out with 0

I should mention that mpg123 is installed, however the server we are using for this project doesn’t have an audio card. Is this a problem? Doesn’t seem to be so far (everything else works great.)
