… in OnDeviceStateChanged - Filter capture (eRender) device events in OnDeviceStateChanged via IMMEndpoint.GetDataFlow to prevent unnecessary playback reinit when input devices change state - Track reconnected device GUID when state transitions to ACTIVE - Add reconnection detection in sndDevicesImplementDeviceRules to auto-select reconnected playback devices (fixes BT headset reconnect after UNPLUGGED) - Clear reconnection state on reinit
… system resume - Call SetThreadExecutionState(ES_CONTINUOUS | ES_SYSTEM_REQUIRED | ES_DISPLAY_REQUIRED) when audio processing starts to prevent system sleep during playback - Revert to SetThreadExecutionState(ES_CONTINUOUS) when processing stops - Handle PBT_APMRESUMEAUTOMATIC power event: check device changes and restore power state after system resume from sleep - Clear execution state on controller destruction

Summary
Prevents the system from sleeping while FxSound is actively processing audio. Also handles system resume from sleep and RDP session changes to ensure audio processing continues correctly.
Changes
SetThreadExecutionState — Sleep prevention
SetThreadExecutionState(ES_CONTINUOUS | ES_SYSTEM_REQUIRED | ES_DISPLAY_REQUIRED)to prevent system sleep and display off.SetThreadExecutionState(ES_CONTINUOUS)to allow normal power management.PBT_APMRESUMEAUTOMATIC — System resume handler
Added
WM_POWERBROADCASTcase in the message window callback. WhenPBT_APMRESUMEAUTOMATICfires after resume from sleep:audio_passthru_->checkDeviceChanges()to refresh device state (devices may have changed during sleep)setPowerState()to re-activate audio processing with the stored power stateFiles Changed
