- The audio driver tests (test_ossaudiodev.py and

test_linuxaudiodev.py) are no longer run by default.  This is
  because they don't always work, depending on your hardware and
  software.  To run these tests, you must use an invocation like
    ./python Lib/test/regrtest.py -u audio test_ossaudiodev

Lib/test/test_linuxaudiodev.py
