I see no problems with audio there:

LiveStreamPacketizerCupertino.handlePacket[live.interleaved/_definst_/103.stream]: Audio codec:AAC is
Compatible:true

VLC plays audio fine if receiving directly from IP cap

what can be a problem?

thank you

Does it play in Wowza example LiveVideoStreaming player:

Server: rtmp://[wowza-address]:1935/live.interleaved

Stream: 103.stream

What does the VLV codec info show?

Paulo,

Are you playing the source in VLC? Or are you re-streaming and playing the Wowza stream in VLC?

What does VLC report the audio codec as when you play the source in VLC?

Paulo,

The video and audio codecs for the upd stream look right. Are you following this guide? :
