Respectfully, I'm not sure I understand what it is that you are
suggesting.

Is it your intention to suggest that instead of adding controls to the
machine driver, I should instead write a codec driver to contain those
controls?

Or is it your intention to suggest that something within the kernel is
already aware of the rate to be set, and it is that which should set the
rate rather than a control?
