Which delay value to take is pretty specific to machine.  Removing
delay will likely cause problem on other machines.

So, if we'd remove delays, do it only for tested machines, not do
blindly to all machines using the same codec chips.  The pop noise
isn't only determined by a codec chip but rather influenced by the
whole hardware analog design.
