See bug 376374 and my associated change in bzr.

I have access to three different HDA controller/codec combinations
(Nvidia/Conexant, Intel/IDT, and the last escapes me atm) where
setting both PCM and Master to 100% does not reveal artifacts. PA also
is not configured to do absurd attenuation.

Yes, this bug report has become severely polluted.
