Actually, you should have dropped the CLK_SET_RATE_PARENT above.

Before, the rate propagation was stopped by the input clock but now,
there no such thing so the rate propagation must be stopped here.

It was almost impossible to know without testing audio, so fixed it
when applying the change.

Thanks for this rework !
