Not really, if the above commands do not work, then you have to report a
bug to ALSA on their bugtracker because it is an ALSA bug
(unfortunately)...

ALSA is supposed to give good results with that configuration.

Notice that ALSA 1.0.11 had a few bugs that were fixed on Debian, I
don't know for other distributions. The symptoms were : bad quality and
segfaults.
