No, but here is
http://www.mail-archive.com/linux-media@xxxxxxxxxxxxxxx/msg15335.html

I know for sure, that I was totally baffled, when Manu, Oliver and
Hartmut did start talking about big head room for improvements on the
tda826x, given the results I had on the tda8261 compared on m$ for both.

The flaw on linux was on the tda8261.

I'm sure I did not shut up, but don't have a link for now.

Thanks to Julian in the first place I would expect.

Cheers,
Hermann

We always will have bugs.
