I use fps filter, there are problems with sound

The sound goes well for about 100 seconds and then breaks off.

    FFmpegFrameGrabber grabber = new FFmpegFrameGrabber("file.mkv");
    grabber.start();

    FFmpegFrameRecorder recorder = new FFmpegFrameRecorder("rtmp://live-fra.twitch.tv/app/live_", 1920, 1080, 2);
    recorder.setInterleaved(true);
    recorder.setVideoOption("tune", "zerolatency");
    recorder.setVideoOption("preset", "veryfast");
    recorder.setVideoOption("crf", "24");
    recorder.setVideoOption("threads", "2");
    recorder.setVideoBitrate(4_000_000);
    recorder.setPixelFormat(AV_PIX_FMT_YUV420P);
    recorder.setVideoCodec(avcodec.AV_CODEC_ID_H264);
    recorder.setAudioCodec(avcodec.AV_CODEC_ID_AAC);
    recorder.setFrameRate(30);
    recorder.setGopSize(60);
    recorder.setAudioQuality(0);
    recorder.setAudioBitrate(grabber.getAudioBitrate());
    recorder.setSampleRate(grabber.getSampleRate());
    recorder.setAudioChannels(grabber.getAudioChannels());
    recorder.setFormat("flv");
    recorder.start();

    String scale = recorder.getImageWidth() + ":" + recorder.getImageHeight();
    FFmpegFrameFilter filter = new FFmpegFrameFilter("fps=fps=30,scale=" + scale + ":force_original_aspect_ratio=1,pad=" + scale + ":(ow-iw)/2:(oh-ih)/2", "volume=2.5", grabber.getImageWidth(), grabber.getImageHeight(), 2);
    filter.setAudioChannels(grabber.getAudioChannels());
    filter.setSampleFormat(grabber.getSampleFormat());
    filter.setSampleRate(grabber.getSampleRate());
    filter.setFrameRate(grabber.getFrameRate());
    filter.start();

    grabber.setVideoFrameNumber(10000);
    grabber.setAudioFrameNumber(10000);

    FPSCounter fpsCounter = new FPSCounter(fps -> System.out.println("Frame Rate Push - " + fps));

    while (true) {
        Frame grab = grabber.grabFrame(true, true, true, false, false);
        if (grab != null) {
            filter.push(grab);
            Frame frame = filter.pull();
            if (frame != null) {
                recorder.record(frame);
            }
            fpsCounter.render();
        }
    }
