No more sound when converting DV to xvid

[RanXerox]

Hello,

I used Ffmpegx 0.0.9s without no problem with a long time
I 'm under Tiger
Since I have installed a M-Audio revolution card, I have no more sound in the preview of my mov files and in the final encoding. ((

I tryed to install a fresh system on an external disk without installing the sound card drivers, still no sound.

Dunno really where it come from. It tryed with some mov file, some vob, same thing, no more sound.
In Mplayer or Quicktime, theses file have sound and no problem.

Could someone help me.

Thanks

After verification, it seems only DV and VOB files have no sound.
I can hear avi in preview.

I tryed with Ffmpeg or Mencoder, still no sound. Tryed 'decode with quicktime' too.

Please help
