if i'm publishing audio with AudioPublisher and then call stop(), i get a null object reference, i've pasted the stack trace below.  the offending line of code is in AudioPublisher:976:

if ( _mic.codec.toLowerCase() == SoundCodec.NELLYMOSER.toLowerCase() )

_mic.codec is null.  i guess the codec gets set to null somehow after the publishing is stopped?

i really don't want to monkey patch AudioPublisher.  is there something i'm doing wrong? or some kind of workaround to avoid this?

TypeError: Error #1009: Cannot access a property or method of a null object reference.
