 [drain_silence INT]

i find this wholly inadequate as a description.
specifically, it's missing a motivation.

and how would one use this in a meaningful way, given that the actual silence size is dependent on the period size and preferably the pointer alignment?

what i could imagine _hypothetically_ making sense is making the 1/10th sec "overshoot" configurable, as it's hardware-dependent. but in practice, i don't see how that would be actually useful, as the cost of doing too much is negligible, and the default you chose seems more than safe enough.
