After clearing the sysclk, the codec should 'pretend' to support all rates, right? (no sysclk -> no rate constrains)
Indeed yes, so a normal pattern would often be setting a sysclk rate in set_bias_level(on the way up)/hw_params and clearing it in set_bias_level(on the way down). That way whilst the device is powered up it is fixed at a certain rate so as not to disrupt any running audio but whilst powered down you are free to start it up at any rate.
Thanks Charles, it is clear now, sorry for the noise.
