I just found out this patch serie and tested it - but no luck. Could you 
say if I do something wrong or is it due to my device firmware version?

I compiled radio from http://git.linuxtv.org/xawtv3.git to tune and 
"arecord  -r96000 -c2 -f S16_LE | aplay - " to play sound. Just silent 
white noise is heard.

And is there any cheap USB FM-radio device that is known to work on 
Linux ?  I would like to order one...
