When a device is detected (or added via `Provider/AddDevice`), it is

queried for its properties and capabilities. Once this enumeration process

completes, it is announced to clients that are watching for device arrivals

via `Registry/WatchDevicesAdded`.

An `Info` table is returned for each audio device that has been added.

const std::optional<uint32_t> & clock_domain ()

An identifier for the clock domain in which the device's clock hardware

operates. Devices in the same clock domain remain perfectly

synchronized. They may drift relative to some other clock domain, but

their clocks have the same rate, their positions may be offset by an

arbitrary, fixed amount.

There are two special values for clock domain:

* `CLOCK_DOMAIN_MONOTONIC` means the hardware is driven by the system

montonic clock and will always be synchronized with that timeline.

* `CLOCK_DOMAIN_EXTERNAL` means the hardware is not synchronized with any

other known clocks (even any other clocks in `CLOCK_DOMAIN_EXTERNAL`).
