On my Linux box (Red Hat Enterprise 3), test_ossaudiodev hangs forever when I enable it: ./python -E -tt ../Lib/test/regrtest.py -u all test_ossaudiodev test_ossaudiodev Traceback (most recent call last): File "../Lib/test/regrtest.py", line 1178, in ? main() File "../Lib/test/regrtest.py", line 333, in main ok = runtest(test, generate, verbose, quiet, testdir, huntrleaks) File "../Lib/test/regrtest.py", line 473, in runtest the_package = __import__(abstest, globals(), locals(), []) File "/home/guido/projects/python-2.4/dist/src/Lib/test/test_ossaudiodev.py", line 136, in ? test() File "/home/guido/projects/python-2.4/dist/src/Lib/test/test_ossaudiodev.py", line 124, in test play_sound_file(data, rate, ssize, nchannels) File "/home/guido/projects/python-2.4/dist/src/Lib/test/test_ossaudiodev.py", line 63, in play_sound_file dsp.write(data) KeyboardInterrupt This happens both with 2.4.2c1 and with 2.5a0 from current CVS. I know in order to debug you need more info about my audio device, but since I never use audio on Linux, you'll have to talk me through providing the info.
