after the commit ? so that I can either get careless, or waste
time/bandwidth by running each commit twice...
Anyways, files/audio_openbsd.c is a `caching' audio system.
It's much smarter than the old one: uses get encoding to map the reasonable
encodings, does not even cross-check alaw/ulaw when 8 bit/16 bit work okay.
It does keep audio opened all the way instead of closing/reopening all the
time.
and it avoids gratuitous assumptions about PC broken hardware, such as not
having support for 8 bits signed and other brain-damage.
Missing part: it won't convert endianess on the fly when the only `right'
modes have the wrong endianess... this might occur with e.g., a sb16 on
an alpha.
