Audio is not being recorded

Hi:

I have this SDP in my wowza server, for receiving a stream

v=0

o=- 0 3641250070 IN IP4 XX.XX.XX.XX

s=Wowza Media Server

c=IN IP4 XX.XX.XX.XX

t=0 0

m=audio 10000 RTP/AVP 0

a=rtpmap:0 PCMU/8000

a=ssrc:3610129879 cname:user3527564912@host-d993365d

m=video 10002 RTP/AVP 101

a=rtpmap:101 H264/90000

a=ssrc:276642451 cname:user3527564912@host-d993365d

The stream is being received great(I can hear and I can watch it from rtmp://[my-wowza-ip]:1935/[app]/filename.sdp), but when I try to record it with Wowza, the generated .mp4 file has no audio.

With .flv it works, but with .mp4 no.

What can be happening?

It sounds like you are using an audio codex that is not supported by .mp4 container. Perhaps NellyMoser or Speex?

If the audio is Speex, you can transcode it to AAC:

How to set up a Flash application to publish H.264 video and Speex audio to Wowza Transcoder

How to convert Flash Player 11 output from H.264 + Speex audio to H.264 + AAC audio using Wowza Transcoder

Or maybe you can set the audio to AAC or MP3 at the source.
