hum I used to set rate to 48000 with my old 2005 july snapshot and it 
was working even with tuner ... but ok I'll try 32000
i've tried alsa and I had the same results, that is no sound with tuner 
but line in sound with composite and svideo
do I need some special stuffs compiled in my kernel except from config_snd ?
about old modules still loaded this can't be since I build my system 
from scratch each time i try a new kernel / driver into an ext2 file, 
which I put on a 32MB flash disk and boot on it ... so I'm sure I'm not 
using my old v4l snapshot, but the 2.6.22.19 v4l drivers

I'll let you know if I can make it work
