[flexcoders] Microphone soundTransform and SPEEX codec bug

[Ryan Graham]

Hi All,

 

Can anyone else confirm the following bug? When using a SoundTransform
to set the Microphone volume to 0 (to avoid feedback), you get the
expected silent behavior with the default Nellymoser codec, while still
seeing microphone activity. If you switch the Microphone's codec to
SPEEX, the soundTransform volume setting of 0 is ignored. I tried sdks
3.2 and 3.3, and players 10.0.12.36 and 10.0.22.87.  If there's already
a JIRA bug, I'd like to vote for it, otherwise I'll create one.
