On current Fedora systems, test_ossaudiodev is implicitly skipped even when the audio resource is enabled due to the absence of the `/test/dsp` device: ``` $ ./python -m test -v -uaudio test_ossaudiodev [...] 0:00:00 load avg: 0.33 [1/1] test_ossaudiodev test_ossaudiodev skipped -- [Errno 2] No such file or directory: '/dev/dsp' test_ossaudiodev skipped 1 test skipped: test_ossaudiodev Total duration: 31 ms Tests result: SUCCESS ``` And while PulseAudio does provide an OpenSoundSystem emulation mode, it apparently isn't sufficient for the Python extension module's needs: ``` $ padsp ./python -m test -v -uaudio test_ossaudiodev [...] 0:00:00 load avg: 0.41 [1/1] test_ossaudiodev test_mixer_methods (test.test_ossaudiodev.OSSAudioDevTests) ... ok test_on_closed (test.test_ossaudiodev.OSSAudioDevTests) ... ok test_playback (test.test_ossaudiodev.OSSAudioDevTests) ...
