Please use a C++ comment for the whole block to make things look more consistent.

AFAICT this will only work well if max is 1, just hard code that.

Please use mixer-test to verify that your controls conform to the expected API, the return value here is not what's expected - it should be a negative value for an error, 0 for no change and 1 for change.

Shouldn't this be a Switch?
- SOC_SINGLE("ALC Enable", NAU8325_R2E_ALC_CTRL3,
NAU8325_ALC_EN_SFT, 1, 0),
ALC Switch.

What happens if someone enables clock detection while things are powered up?
