no new flags, please, and if so, the other way round.
Default is 16 bit, if (the reintroduced) -rme flag is present
try 32.

There is no other card for OSS that supports 32 bit AFAIK.
OSS kernel interface will die, I don't want to try to push new
formats into it.

The way to go is definitely ALSA, or better jack (jackit.sourceforge.net).
The jack audio server allows several applications to share the sound
device, it is supposed to be low latency and it is callback based.
(and has a simpler API, only floating point format, non-interleaved
samples, which all fits pd very well).

In order to make it work on OSS based systems too, jack can easily
be extended by a OSS backend, which would make it runable with
boths API's and pd doesn't have to care about them anymore.

I am willing to implement this, if we can agree on it.

All of this has to be seen in a larger context, because the
resurrection of the DeMuDi distribution has as one goal to be
based on the Jack server for doing AudioI/O.

Well, I hope we can manage to show pd at its best within this
distribution, with all externals, docs, examples, etc etc that
all people are contributing here ...
