To python-dev: Sorry for the hiatus.
To python-list: does someone who knows about audio and can run linux
want to play with this (Ping and I fall into just one of these
categories each!).

Cool.
Okay, i just discovered sunau.py. Here's my real shot at test_linuxaudiodev.py. Can you give this a try?
---- test_linuxaudiodev.py ---- from test_support import verbose, findfile, TestFailed import linuxaudiodev import os, sunau
formats = {("ULAW", 1): linuxaudiodev.AFMT_MU_LAW, ("NONE", 1): linuxaudiodev.AFMT_S8, ("NONE", 2): linuxaudiodev.AFMT_S16_BE}
def play_au_file(path): au = sunau.open(path, "r") data = au.readframes(sunau.AUDIO_UNKNOWN_SIZE) au.close()
spec = (au.getcomptype(), au.getsampwidth()) if not has_key(formats, spec): ^^^^^^^ Oops?
raise "audio format not supported by linuxaudiodev"
Maybe you mean: raise TestFailed, "audio format not supported by linuxaudiodev" ? I thought string exceptions were deprecated...
dsp = linuxaudiodev.open("w") dsp.setparameters(au.getframerate(), au.getsampwidth() * 8, au.getnchannels(), formats[spec]) dsp.write(data) dsp.close()
def test(): play_au_file(findfile('audiotest.au'))
test()
This doesn't work. I don't really understand why. For audiotest.au, |spec| is ("ULAW",2), which I don't think is right; file(1) says audiotest.au: Sun/NeXT audio data: 8-bit ISDN u-law, mono, 8000 Hz So I think this could be a bug in sunau. The other data (au.getframerate(), au.getnchannels()) agrees with file(1). Anybody have a better idea? Cheers, Michael Hudson, BA (as of today! woohoo!)
