* This drains the PFE_SOUND measurement data queue into _pf_data. * PFE_SOUND measurements are made by the mixer thread and so cannot be stored * into _pf_data directly, because this would not be thread safe and would violate * the invariants of the FPS and frame graph windows. * @see PerformanceMeasurement::~PerformanceMeasurement() */
