am b177e8a7: Merge "AudioTrack: Prevent stop() from reissuing last marker event" into mnc-dr-dev

        mTimestampStartupGlitchReported = false;

        mRetrogradeMotionReported = false;

        // If previousState == STATE_STOPPED, we reactivate markers (mMarkerPosition != 0)

        // as the position is reset to 0. This is legacy behavior. This is not done

        // in stop() to avoid a race condition where the last marker event is issued twice.

        // Note: the if is technically unnecessary because previousState == STATE_FLUSHED

        // is only for streaming tracks, and mMarkerReached is already set to false.

        if (previousState == STATE_STOPPED) {

            mMarkerReached = false;

        }

        // For offloaded tracks, we don't know if the hardware counters are really zero here,

        // since the flush is asynchronous and stop may not fully drain.

        // We save the time when the track is started to later verify whether

    mProxy->interrupt();

    mAudioTrack->stop();

    // the playback head position will reset to 0, so if a marker is set, we need

    // to activate it again

    mMarkerReached = false;

    // Note: legacy handling - stop does not clear playback marker

    // and periodic update counter, but flush does for streaming tracks.

    if (mSharedBuffer != 0) {

        // clear buffer position and loop count.
