I see no problems with audio there:

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?

Richard

[Richard_Lanham]

Paulo,

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

The original stream as audio and video but when i open wowza in vlc i only have the video (in codec details there is only one stream).

What can i do ?
