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:

2. "Even if it sucks in general". In this case, what solution
would you propose to get the problem of the white
noise fixed?
