Newer SB16 chips (Vibra 16C and later) have extended mixer controls. This detects them and enables automatically if present.
Supported extended controls: Synth Playback Switch PCM Playback Switch Beep Playback Switch Master Playback Switch PCM Capture Switch Master Capture Volume Master Capture Switch
Vibra 16XV has an additional Aux input which is used on SF16-FMD and SF16-FMD2 cards to connect the onboard FM tuner: Aux Playback Switch Aux Volume Aux Capture Switch
