Hi Lennart, thanks for your opinion. I am puzzled with the "even if it sucks" part, what does it mean? I see 2 possible interpretations of it: 1. "Even if it sucks with some drivers that have bugs, like the saa7134_alsa one". If that interpretation is what you implied, then could you please also evaluate the fix like this one: http://www.spinics.net/lists/linux-media/msg35237.html 2. "Even if it sucks in general". In this case, what solution would you propose to get the problem of the white noise fixed?
