Description Daniel Limia 2021-11-08 12:39:50 PST

We run a video interviewing company and our software records video interviews from candidates.

We are experiencing MediaStreamTracks crashing with the error "A MediaStreamTrack ended due to a capture failure" when a user is using Airpods as mic input. (Not sure if other earbuds also cause these issues). The user does not necessarely have to remove the Airpods in order for the track to crash. It happens automatically.

Using the same hardware and running the same software the issue does not occur on Chrome, Edge and Mozilla.

There is no issue on iPhone/iPad either.

Thanks for filing, is there some way we can reproduce this issue on our end? Do you have a test case or test credentials you can share? This can be via email if that works better than posting here. Thanks.

We are also encountering this error with Safari 15.1 on MacOS. 
For us, it seems to only occur when the application makes use of the AudioContext API. 
The issue occurs without using Airpods, and is also reproducible on iOS. 

This is a significant problem, as our application includes WebRTC based video-chat and outputs dynamic sounds. 

In Chrome / Firefox and Safari versions pre 15, this issue doesn't occur at all. 

It seems that there are other bug reports in Bugzilla which may be related to this one, but it's really hard to pin point exactly.. 

As more users are gradually updating their Safari version to 15.1, this issue is affecting more and more users.

Actually, I'm no longer sure that AudioContext is related.. but I'm not ruling it out. 

I'm able to reproduce the issue in many video chat platforms, such as Google Meet and Twilio quickstart React app. 

Steps to reproduce on Google Meet: 

1. Before starting, make sure that your default audio input device is set as your built-in microphone. 
2. Visit https://meet.google.com -> New Meeting -> Start an instant meeting.
3. Allow “meet.google.com” to use your camera and microphone.
4. Go to settings and select a Bluetooth device (I tried with Sony WH-1000XM2) or a USB device (I tried with Logitech C922 Pro Stream Webcam).

The console shows the error "A MediaStreamTrack ended due to a capture failure".
The microphone volume indicator is not moving anymore.

Safari Version 15.2 (17612.
macOS Monterey Version 12.1 (21C52)

Would just like to say this is also impacting my clients too

Is it still an issue in the latest Safari 15.4 release?
If so, can you provide some repro steps?
Comment 7 Dan Jenkins 2022-03-23 08:37:46 PDT
hey @youenn !

yes, m1 mac, safari 15.4, monterey 12.3

Open up https://yourclinic.doxy.me/tvk
open up the web inspector console
type in a name like testing
allow permissions
once it loads... top right... hover over the video and change your mic device a few times between airpods and others available and you'll eventually get the capture failure error.

Forgot to say, I can do a sysdiagnose if you'd like...
Comment 9 youenn fablet 2022-03-23 10:13:28 PDT
Thanks, I was able to reproduce.

We are seeing the same error randomly when we use MediaDevice Interface in Media stream API to change the audio source device in Safari 15.5.

The issue is not specific to airpods for us. The error appears when an audio source is changed. It doesn't appear consistently, and can be seen only once in multiple attempts to change the device. It doesn't occurs in chrome.

I am also seeing the same issue on Safari Version 15.5 (17613.
running on MacOS Monterey (12.4)

Steps to repro were:
0. Pair a bluetooth headset with audio input/output capabilities with the Mac.
1. Kill any existing instance of Safari
2. Start off with your in-built input output device.
2. Start a new instance of Safari
3. open https://makarandp0.github.io/audioRender/
4. Click on GetLocalAudio (This will acquire local audio track)
5. Click on RenderLocalTrack (This will render acquired track on canvas element)
6. start your bluetooth headset, so that it connects to MacOS.
7. After few seconds turn off your bluetooth headset.
8. Notice that the audio rendering stops although the readyState=live.

Repeat step 5-7 few times, and you will see a "MediaStream ended due to capture failure"
