Are you using
- plain alsa
- alsa with oss emulation
- plain oss

When you have audio working, use this:

transcode -x v4l2,v4l2 -i /dev/video0 -p /dev/dsp0 --export_profile
dvd-ntsc -y ffmpeg -o video.m2v -m audio.ac3 [ ... denoising and
cropping ... ]
mplex -f 8 -o both.vob video.m2v audio.ac3
dvdauthor -o dvd both.vob
dvdauthor -o dvd -T
