Subject: validate microphone settings when leaving the record options and when
 USDX is started: - check if a user is assigned to multiple devices. If this
 is the case either do not leave the record options (if we already are there)
 or enter the record options (if USDX was started) - the check is performed by
 calling TAudioInputProcessor.ValidateSettings()
