mixer: configure legacy mixer before the audio outputs
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().
