I’m with new the Wowza, I would appreciate if your can help me with this problem.

I try to play, through the Wowza it signal a live digital TV .The protocol is UDP and are MP4 codec. However there are only video playing, while the audio is not heard. When I test with VLC is played normally.

For broadcast through the Wowza I make use of “Application Live”, putting the URL in “stream file” and finally activating the transmissión. I need to do additional configuration?.

Thank you.
