mixer: configure legacy mixer before the audio outputs

Browse Source 
Reimplemented the legacy mixer configuration: copy the deprecated
configuration values into the audio_output section.  Don't configure
the mixers twice (once for the audio_output, and a second time for the
legacy values).

This requires volume_init() to be called before initAudioDriver().
