100    Open a mixer device and return an OSS mixer device object.   *device* is the
101    mixer device filename to use.  If it is not specified, this module first looks
103    found, it falls back to :file:`/dev/mixer`.
340 The mixer object provides two file-like methods:
345    This method closes the open mixer device file.  Any further attempts to use the
346    mixer after this file is closed will raise an :exc:`IOError`.
351    Returns the file handle number of the open mixer device file.
358    This method returns a bitmask specifying the available mixer controls ("Control"
361    mixer controls---the :const:`SOUND_MIXER_\*` constants defined at module level.
362    To determine if, for example, the current mixer object supports a PCM mixer, use
365       mixer=ossaudiodev.openmixer()
366       if mixer.controls() & (1 << ossaudiodev.SOUND_MIXER_PCM):
371    :const:`SOUND_MIXER_PCM` controls should suffice---but code that uses the mixer
372    should be flexible when it comes to choosing mixer controls.  On the Gravis
