I have to correct myself again, the first patch I submitted is working, I'm 
sorry. However, it seems that disabling the AA-loopback path is not necessary, 
muting the input 0x0b in node 0x0c (as it was suggested here: 
https://bugs.launchpad.net/ubuntu/+source/alsa-driver/+bug/1252733/comments/26) is enough to get rid of the white noise.

What is the proper way to fix this problem?

Regards,

Gabriele
