Created attachment 461668 [details] sysdiagnose_2022.08.16_13-53-25+0300_iPhone-OS_iPhone_20A5339d.tar.gz Added additional sysdiagnose file: sysdiagnose_2022.08.16_13-53-25+0300_iPhone-OS_iPhone_20A5339d.tar.gz Seems that we have bigger reproducibility if AirPods connected with device => also audio becomes broken. And if we disconnect AirPods and rejoin WebRTC join, we don't have outgoing video and audio and Safari freezes. Let me know if there is a need to add additional information or log file.
From the logs, I can see some errors like: 2022-08-16 11:42:10.311782+0300 0x55A9 Error 0x0 541 com.apple.WebKit.GPU: (WebCore) [com.apple.WebKit:WebRTC] LocalSampleBufferDisplayLayer::layerErrorDidChange (9958DCCA7039740) 2022-08-16 11:42:10.589290+0300 0x55A9 Error 0x0 541 com.apple.WebKit.GPU: (WebCore) [com.apple.WebKit:WebRTC] AudioMediaStreamTrackRendererInternalUnit::createAudioUnit AudioUnitInitialize() failed, error = 560557684 We fixed related errors in the latest iOS 16 beta 6. @Madara, could you have a try?

Removed sysdiagnoses, as they prevented importing to Radar, and sharing them isn't good for privacy. Will re-attach to radar directly.
Hi unfortunately, I am still able reproduce defects with latest available iOS Beta version: iOS 16 beta 6 (20A5349b), device: iPhone 11 Pro Max I created folder in Google drive and shared it with and there a new sysdiagnose file: https://drive.google.com/file/d/1wvzEYrbKWsZv1zujNIDRNRtEvs9tfBBV/view?usp=sharing sysdiagnose_2022.08.17_14-54-30+0300_iPhone-OS_iPhone_20A5349b.tar.gz

Hi! Added additional sysdiagnose file (use case: AirPods connected => navigate to Youtube and back): https://drive.google.com/file/d/1ubW5LCOkLYull6oozHQB3hH1WD52ykPF/view?usp=sharing sysdiagnose_2022.08.18_12-34-27+0300_iPhone-OS_iPhone_20A5349b.tar.gz
From the last sysdiagnose, I can see: 2022-08-18 12:30:25.760241+0300 0x1276 Error 0x0 319 com.apple.WebKit.GPU: (WebCore) [com.apple.WebKit:WebRTC] AudioMediaStreamTrackRendererInternalUnit::createAudioUnit AudioUnitInitialize() failed, error = 560557684 This should be fixed by bug 243249. I also see that we are stopping past captures since a new camera or microphone is selected, (for instance switching from front to back camera): 2022-08-18 12:32:40.462696+0300 0x1276 Error 0x0 319 com.apple.WebKit.GPU: (WebKit) [com.apple.WebKit:WebRTC] Ending microphone source as new source is using a different device. 2022-08-18 12:32:55.025852+0300 0x1276 Error 0x0 319 com.apple.WebKit.GPU: (WebKit) [com.apple.WebKit:WebRTC] Ending camera source as new source is using a different device. @madara, can you detail which WebRTC website you were using and which actions you did on this website. I can see YouTube being used between 12:30 until 12:32. At 12:32, I can see the website is asking for microphone/camera access and is switching from AirPods to iPhone microphone, so we end the AirPods microphone track.
Respecting the confidentiality, an email was sent with additional information to Youenn. Let me know if there is a need to make additional tests / we need to give more information about our issue.
I’m not able to reproduce described issue in ticket with iOS 16.2 Beta 2, build: 20C5043e, iPhone 11 Pro Max. @Youenn, should we see the fix with this version? Bug linked with https://bugs.webkit.org/show_bug.cgi?id=244505
Bug is not reproducible anymore. Tested OK on: * iPhone 11 Pro Max | iOS 16.2, build: 20C65 * iPhone 12 Pro Max | iOS 16.2, build: 20C65 * iPhone 14 | iOS 16.2, build: 20C65 Thanks!
