AudioLevelObserver is not work in rust API

mediasoup libraries

Hello I’m building rust server using mediasoup version 0.18 The voice chat is work but volume observer is not working. help me please

// here is observer created and print volume change
let mut options = AudioLevelObserverOptions::default();
        options.max_entries = NonZero::new(5).unwrap();
        options.threshold = -40;
        options.interval = 300;
        let audio_level_observer = router
            .create_audio_level_observer(options)
            .await
            .expect("Failed to create audio level observer");

     let _ = audio_level_observer.on_volumes(move |volumes| {
            // volumes: &[AudioLevelObserverVolume]
            // 각 volume에 대해 producer_id → session_id 매핑
            for v in volumes {
                let volume = v.volume;
                let producer_id = v.producer.id(); // ProducerId
                println!(
                    "Audio level detected - Producer ID: {}, Volume: {}",
                    producer_id, volume
                );
            }
        });


// other file creating producer
if producer_kind == mediasoup::prelude::MediaKind::Audio {
                            let options =
                                mediasoup::prelude::RtpObserverAddProducerOptions::new(producer_id);
                            self.audio_level_observer
                                .add_producer(options)
                                .await
                                .expect("Failed to observe producer audio level");
                            info!(producer_id = %producer_id, "Audio level observer registered for producer");
                        } else {
                            info!(producer_id = %producer_id, kind = ?producer_kind, "Producer is not audio, skipping audio level observer registration");
                        }

When I run server println prints nothing even I’m talking what is wrong?

currently it seems like extension id mapping missmatch. The server uses number 10 but client uses 1 for voice-level extension How can I sync the id?

Never mind I made decision that chrome browser or mac os did not implement extension header for wbeRTC So I just made it client send the spaking activity to server
