augustss 6616d47838 - Change audio_hw_if a little: set_param now sets the play and record modes
at the same time instead by using two different calls.  This enables
  it to check more easily if the combined mode is all right.
- Improve the error checking in audio.c.
- Add a new audio property, AUDIO_PROP_INDEPENDENT, show if the
  play and record settings are independent.
- Fix some buglets in audio.c.
