class WatchGainState
Defined at line 1469 of file fidling/gen/sdk/fidl/fuchsia.hardware.audio/fuchsia.hardware.audio/cpp/fidl/fuchsia.hardware.audio/cpp/markers.h
Get the gain state via a hanging get. The driver will reply to the first `WatchGainState`
sent by the client and this reply must include a `gain_db` set to 0dB or lower. The driver
will not respond to subsequent client `WatchGainState` calls until the gain state changes
from what was most recently reported.
If `WatchGainState` is called for a second time before the first call has completed, then
the protocol channel must be closed with the error `ZX_ERR_BAD_STATE`.
