This is not a hack, wsa codec requires gain to be programmed after the clk is enabled for that particular interpolator.
Ok, but then it's also broken as, as I mentioned off-list, these registers are cached so unless companding is enabled, the write on enable will have no effect.
I was obviously confused here, and indeed tests reveal that those writes are needed for any prior updates to take effect (e.g. volume changes while the codec is runtime suspended).
I've just sent a v2 here:
