WebDec 14, 2024 · PortCls can now use a new power management interface to generate a new D3 exit latency tolerance, and then communicate it dynamically to the audio miniport driver. These tolerances are represented as PC_EXIT_LATENCY enumeration values. For more information about the new power management interface, see … WebAug 24, 2024 · PortCls calls the audio driver's D3ExitLatencyChanged method to set the maximum latency to either 35 milliseconds or 300 milliseconds. The audio driver must respect the maximum latency tolerance and not enter a low-power state that requires a resume latency larger than the value specified by PortCls in the D3ExitLatencyChanged …
