Capturing sound properly

[newwave451]

I have captured a video streaming with both video and sound.

The capture works perfectly when I play the recording with DEBUT

But when I export the capture in MP4 and play the file with VLC, I hear no sound

I have also exported the sound captured in MP3. I can manage to hear something from the MP3 file with an audio editor but here again no sound when I play the Mp3 file with VLC

Rings a bell to anyone? Any clue?

When you export or save the video, are you using the H264 encoder?  Have you tried using the MPEG4 encoder when exporting the capture video?  Could you also try playing the exported video using another media player?  Also, you can try exporting the audio using a different bitrate, for example, 192 kbps and test again.
