IOS RTMP live stream audio

Question

Hi guys hopefully some of you will be able to help me.
I am trying to stream audio from a live RTMP feed using the NetConnection and NetStream classes. I've managed to get my app running no problem on Android, however I am having some major difficulties getting it to play the audio back on iPad. Interestingly it works in the device emulators when debugging, however I'm assuming this is not really an accurate representation. I've tried streaming the RTMP in both AAC and MP3, but with no luck from either. I can verify through debug that it has connected to the stream, however I just get no audio playing.
Everything I've read about seems to suggest that this is possible on IOS as I'm only interested in audio and not video. Can anyone help?
Code sample below (it's quick and dirty! ).
THanks in advance!

Answer 1

Just an update on this for anyone coming along after me.
I've managed to get this working on MP3 but not AAC (I guess AAC just isn't supported?).
My problem was the buffertime. The docs seemed to indicate it shoudl be set to 0 for live streaming, however switching it to "1" solved my problem on the particular stream I was pointing at.
So essentially justchanged the above line:
                                        ns.bufferTime = 0;  
to
                                        ns.bufferTime = 1;  
Would be great to find out if anyone has gotten AAC working however...
