An easy answer might then be "don't do that". :)
Are you checking DSP_CAP_DUPLEX?
And what makes you say "as though it were /dev/dsp"? /dev/audio is
supposed to default to 8-bit, /dev/dsp is supposed to default to 16-bit.
Are you following the OSS guide at
http://www.opensound.com/pguide/oss.pdf ? It doesn't contain a few
2.3.x features, but it should be fairly close to the 2.2.x API.
