ah. actually, 16 million is exactly right, because the ALSA PCM device
"default" is, by default, using the plug layer and is deliberately
designed to handle "any" number of channels requested by the user.
this is a well known issue with ALSA. fernando (from ccrma/snd) and
abramo and i and jaroslav and some others discussed this at great
length on alsa-devel earlier this year.
its a *deeply* problematic area. your patch, unfortunately, isn't the
correct solution, not by a long shot. however, i will apply it because
it will help JACK run for the time being without us having to define
the correct solution for people (which involves the ALSA conf files,
and what "default" actually means). and thanks for the other patches too.
thanks.
