233473 2021-11-24 07:05:21 -0800 audio track error: A MediaStreamTrack ended due to a capture failure 2023-03-01 03:50:50 -0800 1 1 1 Unclassified WebKit WebRTC Safari 15 Mac (Intel) macOS 12 RESOLVED CONFIGURATION CHANGED InRadar P2 Normal --- 1 vad.filippov webkit-unassigned andy a.xalilov1997 bfulgham csantos daginge daniel.stabel francesco.durighetto jesmith petez stuartmemo tal.bar2005 webkit-bug-importer youennf oldest_to_newest 1817641 0 vad.filippov 2021-11-24 07:05:21 -0800 In Safari on macOS 15.1 Beta when audio track is acquired in Safari it always ended immediately with error 'A MediaStreamTrack ended due to a capture failure'. Could be reproduced using https://webrtc.github.io/samples/src/content/getusermedia/audio/ 1817651 1 webkit-bug-importer 2021-11-24 08:32:51 -0800 <rdar://problem/85729477> 1824730 2 tal.bar2005 2021-12-16 05:51:35 -0800 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 example provided by Vadim doesn't reproduce this error for us. 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. 1829568 3 csantos 2022-01-10 11:17:39 -0800 A lot of our customers are also starting to see this error. For us, it happens on USB and Bluetooth devices and when the application uses Web Audio API. 1838595 4 francesco.durighetto 2022-02-08 03:27:47 -0800 Safari 15.3 bug still present. Can riproduce even without webAudio APIs. Steps to reproduce: - connect bluetooth headphones - go to system preferences, audio, input. Set the default input device as the internal microphone instead of Bluetooth device. - open: https://jsfiddle.net/bkwLzcjo/1/ - allow permission to capture and inspect console - select from the dropdown menu the bluetooth input - "A MediaStreamTrack ended due to a capture failure" appears after few seconds in console It's P2 an adequate priority? If we add audioContexts to the page this became even more messy and broken and the majority of conference apps uses the audioContext to display audioLevel... 1838671 5 daginge 2022-02-08 08:00:03 -0800 Possibly dupe or related to https://bugs.webkit.org/show_bug.cgi?id=221192. I guess in this case a PC isn't involved so might be a separate issue. 1844743 6 petez 2022-02-22 09:22:49 -0800 Happening to us regularly now with USB audio devices, Safari is (once again) basically unusable for WebRTC. 1846450 7 andy 2022-02-27 09:19:38 -0800 I get the same error on Safari on both Intel and iPhone with this app https://mdn.github.io/web-dictaphone/ 1876945 8 a.xalilov1997 2022-06-21 04:55:19 -0700 Any updates on this? We are still facing this problem in our webrtc app? For us, capturing an audio device is failing when AudioContext API is used in Safari 15.x. 1885654 9 a.xalilov1997 2022-07-20 23:52:27 -0700 The issue is fixed for me in Safari 15.6 1887061 10 jesmith 2022-07-27 08:50:00 -0700 Although the error message is no longer being reported, switching audio devices still does not work. If you open the audio device you want, it now will work correctly with the device chosen (this wasn't working before). But if you then close that and try to open a different device, things still fall apart. 1887062 11 petez 2022-07-27 08:51:06 -0700 Are you sure about that? I tested it and was able to change devices. 1887076 12 jesmith 2022-07-27 09:14:12 -0700 After some more testing, it turns out that changing devices *does* work. The problem is that when I have bluetooth headphones connected, the gain on the internal mic is dropping to almost zero. This only happens in Safari (I can switch audio input no problem in Firefox, for example, and the gain stays correct). This seems to be a new problem, in that the internal mic gain is super low even if that's the only device I ever use. So it's not related to switching. 1887082 13 youennf 2022-07-27 09:28:37 -0700 (In reply to Joshua Smith from comment #12) > After some more testing, it turns out that changing devices *does* work.

So it's not related to switching. This seems like a different bug, could you file a bug? Also, which Safari version are you using? 1887083 14 jesmith 2022-07-27 09:33:28 -0700 I'll file a bug. I'm using Version 15.6 (16613.3.9.1.7, 16613) on MacOS 11.6.7 1887133 15 jesmith 2022-07-27 12:47:55 -0700 Here's the bug, including a test app to demonstrate it. https://bugs.webkit.org/show_bug.cgi?id=243260 1908665 16 tal.bar2005 2022-10-27 02:38:57 -0700 This bug is definitely NOT resolved! I'm still encountering this bug on Safari Version 16.0 (17614.1.25.9.10, 17614). When selecting bluetooth headphones (WH-1000XM2) as audio input device, I'm getting "A MediaStreamTrack ended due to a capture failure". I was able to reproduce it in Google Meet. This bug makes using Safari + bluetooth headphones for video calls impossible! 1908667 17 tal.bar2005 2022-10-27 02:51:05 -0700 As Francesco Durighetto described, this error occurs when the OS default input device is set at anything other than bluetooth headphones. Still, this issue doesn't occur using Chrome or Firefox. Only Safari.. 1908668 18 youennf 2022-10-27 02:55:33 -0700 @Tal Bar, can you file a new bug? And mention the macOS version (plus ideally send me a sysdiagnose to me at youenn@apple.com)
