Handles hotplugging and playback device selections during calls in the Windows Audio Session API (WASAPI) integration when acoustic echo cancellation (AEC) is enabled.

Implements acoustic echo cancellation (AEC) in the integration of Windows Audio Session API (WASAPI) using the Voice Capture DSP in source (as opposed to filter) mode.

Fixes issues with the Renderer implementation using Windows Audio Session API (WASAPI) related to the playback and/or notify device selections being set to 'none'.

Allows opening the CaptureDevice implementation using Windows Audio Session API (WASAPI) when the playback device selection is set to 'none'.

Allows disabling the playback mid-stream when running Windows Audio Session API (WASAPI) without acoustic echo cancellation.

Fixes an issue in the Windows Audio Session API (WASAPI) integration which could cause the audio capture to fail on certain devices if acoustic echo cancellation is enabled.

Fixes a problem with the Renderer implementation of Windows Audio Session API (WASAPI) which could cause loss of playback after switching the playback device during a call.
