mod_conference crash on transcoding

[zooptwopointone]

Describe the bug
Providing a non-native sound file to mod_conference results in SegFault.

I have tested this with MOH conference_moh_sound and using the CLI conference FILENAME play

playing a Stereo wav or if it is in another format like mp3 will cause a immediate crash. GDB output provided below.

To Reproduce
Steps to reproduce the behavior:
Join a call to a conference and play a stereo audio file. or Mp3 file etc. In this case the file was also remote being pulled in from a http request.

Expected behavior
freeswitch would preform required transcoding for the audio to be compatible with the conference audio without failure.
