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.
Confused as hell, and completely ignorant of computer audio,
Greg
