  AUDCLNT_STREAMOPTIONS_MATCH_FORMAT,
  AUDCLNT_STREAMOPTIONS_AMBISONICS,
  AUDCLNT_STREAMOPTIONS_POST_VOLUME_LOOPBACK
} ;

Constants

AUDCLNT_STREAMOPTIONS_NONE No stream options.
AUDCLNT_STREAMOPTIONS_RAW The audio stream is a 'raw' stream that bypasses all signal processing except for endpoint specific, always-on processing in the Audio Processing Object (APO), driver, and hardware.
AUDCLNT_STREAMOPTIONS_MATCH_FORMAT The audio client is requesting that the audio engine match the format proposed by the client. The audio engine will match this format only if the format is supported by the audio driver and associated APOs. Supported in Windows 10 and later.
AUDCLNT_STREAMOPTIONS_AMBISONICS
AUDCLNT_STREAMOPTIONS_POST_VOLUME_LOOPBACK The audio client is requesting that the loopback stream tap into the playing audio after volume and/or mute settings have been applied. The default behavior is for the loopback stream to be tapped before volume and/or mute.
