The vendor driver appears to be modifying the gain settings behind the back of user space but these hacks never made it upstream except for some essentially dead code that adds a constant zero to the current gain setting on DAPM events.
Note that the volume registers still need to be written after enabling clocks in order for any prior updates to take effect.
