Just so you know -- i was definitely able to get this to work at some point before when we were trying to fix this. I changed test_linuxaudiodev and it played the .AU file correctly. I haven't had time to survey what the state of the various modules is now, though -- i'll have a look around and see what's going on.
I have three copies of test_linuxaudiodev.py in my Lib/test directory: the original, Ping's version, and Michael Hudson's version. I can't remember who hacked whose, ie. if Michael or Ping's is earlier. Regardless, none of them work. Here's how they fail: $ /python Lib/test/regrtest.py test_linuxaudiodev test_linuxaudiodev 1 test OK. ...but the sound is horrible: various people opined on this list, many months ago when I first reported the problem, that it's probably a format problem. (The wav/au mixup seems a likely candidate; it can't be an endianness problem, since the .au file is 8-bit!) $ ./python Lib/test/regrtest.py test_linuxaudiodev-ping test_linuxaudiodev-ping Warning: can't open Lib/test/output/test_linuxaudiodev-ping test test_linuxaudiodev-ping crashed -- audio format not supported by linuxaudiodev: None 1 test failed: test_linuxaudiodev-ping ...no sound. ./python Lib/test/regrtest.py test_linuxaudiodev-hudson test_linuxaudiodev-hudson Warning: can't open Lib/test/output/test_linuxaudiodev-hudson test test_linuxaudiodev-hudson crashed -- linuxaudiodev.error: (11, 'Resource temporarily unavailable') 1 test failed: test_linuxaudiodev-hudson ...this is the oddest one of all: I get the "crashed" message immediately, but then the sound starts playing. I hear "Nobody expects the Spani---" but then it stops, the test script terminates, and I get the "1 test failed" message and my shell prompt back.
