I have recently been developing an ASIO & WDM audio driver, which is

Now when I encounter the recording call CopyFrom copying samples from
the circular buffer, noise will be generated whenever I encounter
insufficient buffering.
Right. What did you expect? Audio data is continuous. If you can't
generate continuous data, then you get noise.
One alternative is to generate zeros when you don't have data to copy,
but even that can generate pops at the transitions.
