Go to https://webrtc.github.io/samples/src/content/devices/input-output/ with Safari 15. 2. Click the camera mute button in the address bar. 3. hit "pause" 4. then, hit "unpause" 5. Observe the annoying disturbance of hearing yourself, even though you shouldn’t hear anything as there is no one else in the session. 1833633 1 youennf 2022-01-25 00:49:59 -0800 Tested locally on a recent Safari and I am not sure I am able to reproduce. Hearing yourself should happen before pause and after unpause. Are you saying that, before pausing, echo canceller is working great (you can hear some limited feedback) while after unpausing, you are hearing much more feedback? Or is it that volume changed somehow? 1833902 2 misha.behei 2022-01-25 15:53:16 -0800 I actually made a quick jsfiddle instead of using the webrtc.github.io samples. This is the link - https://jsfiddle.net/othm7a5k/3/. Can you please try with this one and let me know if you are able to reproduce the issue? Basically, if you "pause" and then "un-pause" the video using the camera icon in the address bar, you will be able to hear yourself which is not observed when you just join. I'm on Safari 15.2, macOS 12.1 btw. 1835743 3 webkit-bug-importer 2022-01-31 15:13:34 -0800 <rdar://problem/88297045> 1838693 4 daniel.ororke 2022-02-08 08:48:40 -0800 I have discovered that it is also possible to reproduce this bug simply by enabling screen sharing. If you share your screen, this should not cause audio loopback through the speakers. I have also observed that changing the audio input device to something else resolves the problem. 1843519 5 daniel.ororke 2022-02-18 11:08:45 -0800 (In reply to youenn fablet from comment #1) > Tested locally on a recent Safari and I am not sure I am able to reproduce. > Hearing yourself should happen before pause and after unpause. > Are you saying that, before pausing, echo canceller is working great (you > can hear some limited feedback) while after unpausing, you are hearing much > more feedback? > Or is it that volume changed somehow? Hi Youenn! If you are not subscribed to any media (only publishing into the abyss of the internet), you should not hear yourself. Safari seems to play the audio, even when not subscribed to anything. This is not related to echo canceler. Something is piping audio input to the output channel separate from WebRTC or echo cancelation. -Daniel 1843520 6 daniel.ororke 2022-02-18 11:18:31 -0800 For some reason, this is becoming increasingly common. Please prioritize, as it renders video sessions unusable from the audio disturbance. I have observed that if another party is screen sharing, the echo is observed on join - no user interaction is necessary. repro: User A: Publish camera, mic, and screen share. Broken User B: Publish camera and mic on joining a session with User A. Broken User B can hear themselves, and this causes considerable feedback as it is passed unchecked through the noise canceler to User A. If it gets loud enough, the noise canceler clamps down and stops all noise but it restarts as soon as any sound is heard through the microphone. Observation: In this condition, it is as though I have made a direct connection from the mic to the speakers, outside of the typical WebRTC subscription. When wearing headphones, I can hear myself (but no feedback is picked up by the mic since it is played locally to my headphones). You should not hear yourself unless you are subscribing to yourself. Changing the microphone to a different device, then back to the original device may temporarily solve this issue. 1846796 7 daniel.ororke 2022-02-28 15:03:29 -0800 Hello Apple, Please address this! It appears the audio problem is created if: 1. Disable / enable video through browser controls 2. Enable screen sharing 3. Change microphone source Occasionally, changing the audio input source fixes the issue until another of the above actions is taken - but it is inconsistent and more likely to break it if audio is not already broken and therefore not an acceptable workaround. This renders RTC sessions unusable in quite short order if you're just listening to mic/speaker feedback and no one is able to be heard. This is much more impacting than the issue with Nat64IPv4 addressing. 1847798 8 453712 youennf 2022-03-03 02:14:15 -0800 Created attachment 453712 Patch 1847914 9 ews-feeder 2022-03-03 08:59:10 -0800 Committed r290778 (248022@main): <https://commits.webkit.org/248022@main> All reviewed patches have been landed.
