Subject:  In WebRTC.lib, Switch WASAPI playout to timer-driven mode with
 AUTOCONVERTPCM   Use WAVEFORMATEXTENSIBLE and
 AUDCLNT_STREAMFLAGS_AUTOCONVERTPCM to   support devices whose native format
 differs from 48kHz stereo PCM,   such as Bluetooth HFP endpoints (16kHz mono)
 and surround sound   devices (5.1/7.1).

  Replace the event-driven render loop (AUDCLNT_STREAMFLAGS_EVENTCALLBACK)
  with a timer-driven polling loop to avoid a known issue where
  AUTOCONVERTPCM combined with EVENTCALLBACK causes the audio engine to
  stop signaling render events, resulting in premature thread termination.

  Also adds 192kHz to the supported sample rate list, uses the first
  closest-match format from IsFormatSupported as a fallback when no
  exact match is found, and applies the same changes to the recording
  path.
