LGTM
one small leftover duplication that I think was missed during cleanup.
Just to see if I understood it right and document a bit the underlying issue: If the user requests a setting value that is not supported by the actual hardware, it might be changed to an arbitrary value that the driver considers closest to the requested value. This is a problem since the further processing may depend on settings like samplerate and gain having the configured value.
With this change, requesting a value that the hardware cannot accommodate is an exception (stopping flowgraph execution?).
I guess this fail-early paradigm is less error-prone than trying to reconcile the requested and actual settings.
Q: recovering is possible by setting a supported setting and restarting the graph processing?
