In iOS devices we hear very small audio gaps at seemingly random intervals (every few seconds or so) when broadcasting with FMLE using MP3 audio (stereo, 44100 Hz, 96 Kbps as recommended in other forum posts with similar issues). If we broadcast with the same settings in FMLE using AAC audio it seems to be perfect and has no gaps.
We experienced this problem with our Wowza 2 version (2.1.1 build24490). We just now upgraded to Wowza version 3 (3.0.3.09 build969) and still experience the same issue. Also, broadcasting with other encoders with AAC audio seems to work perfectly (Wirecast and nanoStream). Lastly, both MP3 and AAC audio play perfectly with Flash players (we are using Flowplayer).
Is there possibly something that we have setup wrong in our config files that would cause this problem with the audio gaps with MP3 and iOS devices? We can't seem to get rid of them.
