Takashi, as Kevin wrote originally, the problem is not that softvol
doesn't do any format/layout conversions, but that it claims it
does. PA asks softvol for INTERLEAVED samples, softvol agrees to
that -- and actually hands us only NONINTERLEAVED samples because it
doesn't reformat the from the underlying layer.

So, it *is* a bug in softvol. However, you are right that it doesn't
do any conversions.
