I have a UCMA application that sets up a conference, invite some parties into the conference and starts playing some pre-recorded audio (or tts message) into the conference. in the case where it's playing music. As the music plays, the audio would fade in and out as if someone was playing with the volume - turning it down and up.
When this same application is play a text-to-speech message as oppose to a wav/wma, the volume remains constant throughout so this effect seems to happen for playing wav/wma files. Any ideas what might be causing this?
Thanks
