I suspect you don't want to have Gain and Level in there.

A switch is obviously an enable.

As I said in reply to your previous posting this looks like it shouldn't
be here.  A few things jump out as suspicious but not everything you're
doing is clear:

This looks like it should be dynamically managed at runtime, either via
DAPM or in the bias level functions.

These look like platform configuration.

These look like volume controls which should be exposed to users.

This looks like it should be user visible.

This should be configured by the platform.
