the reason for no master playback volume/switch is
master rename as master surround but no headphone playback volume/switch

Title:
[Emulated AD1980 AC97 inside Virualbox 5.0, playback] volume slider
problem
Status in alsa-driver package in Ubuntu:
Invalid
Status in virtualbox package in Ubuntu:
Confirmed
Bug description:
Volume Slider is only controlling PCM channel and is not controlling
Master. In effect, Master is restricting the audio level to the
default of approximately 45 Percent. In order to raise the Master
Volume Level, alsamixer is capable of changing Master. Without
manually raising Master to Max Volume, Volume Slider can only control
volume from 0-45% which is the default level of Master.
