Thank you Carl,

The ac3 file go created, and sound IS GOOD...
as soon as I involve video4linux3, the sound is gone,

# ffmpeg -y -standard NTSC -f video4linux2 -i /dev/video0 -f alsa -i hw:1,0 -acodec ac3 -vcodec libx264 out.mp4

tried with alsa & oss, different video and audio codecs, different versions of ffmpeg.
it seems like v4l2 needs another argument to somehow force the audio....

Thanks again,

Mike
