The appended script works for me. I think the module should be called something like OSS (since it uses the Open Sound System API) with a -I entry in Setup.in to indicate that this will probably need to be specified to find <soundcard.h> (e.g., -I/usr/include/linux for Linux, -I/usr/include/machine for FreeBSD...). I'm sure I'll have other suggestions for the module, but they'll have to wait until I finish moving to California. :) Best, Eric #!/usr/bin/python import linuxaudiodev import math, struct, fcntl, FCNTL a = linuxaudiodev.open('w') a.setparameters(44100, 16, 1, linuxaudiodev.AFMT_S16_LE) N = 500 data = apply(struct.pack, ['<%dh' % N] + map(lambda n: 32767 * math.sin((2 * math.pi * n) / N), range(N))) fd = a.fileno() fcntl.fcntl(fd, FCNTL.F_SETFL, ~FCNTL.O_NONBLOCK & fcntl.fcntl(fd, FCNTL.F_GETFL)) for i in xrange(200): a.write(data)
