>> vlc v4l:/dev/video0:norm=ntsc:frequency=181000:adev=/dev/dsp:audio=0 --sout-display

I obtein video but not sound.... then i read in the vlc forum about saa7134-alsa and i did 

>> modprobe saa7134-alsa index=1
>> dmesg
saa7134 ALSA driver for DMA sound loaded
saa7130[0]/alsa: saa7130[0] at 0xc0101000 irq 217 registered as card 1

>> ls -l /dev | grep audio
