read the header from the .au file and do a sanity check
pass only the data to the audio device
call flush() so that program does not exit until playback is complete
call all the other methods to verify that they work minimally
call setparameters with a bunch of bugs arguments
linuxaudiodev.c:
use explicit O_WRONLY and O_RDONLY instead of 1 and 0
add a string name to each of the entries in audio_types[]
add AFMT_A_LAW to the list of known formats
add x_mode attribute to lad object, stores imode from open call
test ioctl return value as == -1, not < 0
in read() method, resize string before return
add getptr() method, that calls does ioctl on GETIPTR or GETOPTR
depending on x_mode
in setparameters() method, do better error checking and raise
ValueErrors; also use ioctl calls recommended by Open Sound

use PyModule_AddXXX to define names in module
at all (my computer doesn't have a Sound Blaster), this doesn't mean
there's a bug in linuxaudiodev. The only error the test suite skips
is currently ImportError -- so that's what we raise. If you see a problem
with this patch, say so and I'll retract. If you think raising an ImportError
sucks, you're right -- but I ain't gonna buy a SB and I sure ain't gonna
let the test-suite fail on my machine.
