What does "Channel Switch" mean? It looks like this is a mute control
in which case it shoiuld be HP Playback Switch or similar like other
mute controls.
Yes, It is another mute control that is missing on current driver.
This mute control is for headphone volume mute. Is it OK to rename it to
'Headphone Volume Playback Switch'?
In rt5616.c, there is another control named "OUT Channel Switch".
You may want to rename it too.
