To reproduce this we need machine with 2 microphones connected. Steps: 1) get stream from first microphone (str1) 2) attach this stream to some audio node (or put to peer connection) 3) get another stream from second microphone (str2) actual result: observe that str1 now starts playing audio from second microphone some code example to try this //******************************// //get all available microphones let devices = await navigator.mediaDevices.enumerateDevices(); let microphones = devices.filter(d => d.kind === 'audioinput'); //get audio from first microphone let str1 = await navigator.mediaDevices.getUserMedia({audio: {deviceId: microphones[0].deviceId}}); //play first stream let audio = new Audio(); audio.srcObject = str1; audio.play(); //get audio from second microphone let str2 = await navigator.mediaDevices.getUserMedia({audio: {deviceId: microphones[1].deviceId}}); //observe that audio now starts playing audio from second microphone (not from str1) //******************************// 1836919 1 webkit-bug-importer 2022-02-03 06:55:17 -0800 <rdar://problem/88433154> 1838258 2 youennf 2022-02-07 11:22:29 -0800 Can you clarify which platform/application is the target for this request?

The issue was updated (problem was observed on macOS 12, 11 on Safari 15) 1916495 4 463876 ivan.zahrodskyi 2022-12-03 13:43:01 -0800 Created attachment 463876 Example to reproduce this problem Issue is still reproducible I tested on MacBook Pro 16 (2019) MacOS 13.1 Beta (22C5059b) Safari Version 16.2 (18614.3.7.1.3) I created small example. - press GET FIRST - make sure you can hear audio from first microphone - select another microphone in second select - press GET_SECOND after getting second microphone - first is lost you can open console and see that stream1 is not active and audio track has readyState === 'ended' this is in 90% tries..but sometimes first track is still active but audio source is wrong (audio plays from second microphone) In our application there is a case when we have 2 different audio from different microphones which we send via webrtc to remote participants. But because of this issue it doesnt work in safari. 463876 2022-12-03 13:43:01 -0800 2022-12-03 13:43:01 -0800 Example to reproduce this problem test.html text/html 2085 ivan.zahrodskyi PCFkb2N0eXBlIGh0bWw+CjxodG1sIGxhbmc9ImVuIj4KPGhlYWQ+CiAgPG1ldGEgY2hhcnNldD0i VVRGLTgiPgogIDxtZXRhIG5hbWU9InZpZXdwb3J0IgogICAgICAgIGNvbnRlbnQ9IndpZHRoPWRl dmljZS13aWR0aCwgdXNlci1zY2FsYWJsZT1ubywgaW5pdGlhbC1zY2FsZT0xLjAsIG1heGltdW0t c2NhbGU9MS4wLCBtaW5pbXVtLXNjYWxlPTEuMCI+CiAgPG1ldGEgaHR0cC1lcXVpdj0iWC1VQS1D b21wYXRpYmxlIiBjb250ZW50PSJpZT1lZGdlIj4KICA8dGl0bGU+RG9jdW1lbnQ8L3RpdGxlPgo8 L2hlYWQ+Cjxib2R5Pgo8c2VsZWN0IGlkPSJmaXJzdF9taWNyb3Bob25lIj48L3NlbGVjdD4KPGJ1 dHRvbiBpZD0iZ2V0X2ZpcnN0X2J0biI+R0VUIEZJUlNUPC9idXR0b24+CjxhdWRpbyBpZD0iYXVk aW9fcGxheWVyIiBhdXRvcGxheT48L2F1ZGlvPgoKPHNlbGVjdCBpZD0ic2Vjb25kX21pY3JvcGhv bmUiPjwvc2VsZWN0Pgo8YnV0dG9uIGlkPSJnZXRfc2Vjb25kX2J0biI+R0VUIFNFQ09ORDwvYnV0 dG9uPgoKPHNjcmlwdD4KICBhc3luYyBmdW5jdGlvbiBydW4oKSB7CiAgICBjb25zdCBtaWNzMSA9 IGRvY3VtZW50LmdldEVsZW1lbnRCeUlkKCdmaXJzdF9taWNyb3Bob25lJyk7CiAgICBjb25zdCBt aWNzMiA9IGRvY3VtZW50LmdldEVsZW1lbnRCeUlkKCdzZWNvbmRfbWljcm9waG9uZScpOwogICAg Y29uc3QgYnRuMSA9IGRvY3VtZW50LmdldEVsZW1lbnRCeUlkKCdnZXRfZmlyc3RfYnRuJyk7CiAg ICBjb25zdCBidG4yID0gZG9jdW1lbnQuZ2V0RWxlbWVudEJ5SWQoJ2dldF9zZWNvbmRfYnRuJyk7 CiAgICBjb25zdCBwbGF5ZXIgPSBkb2N1bWVudC5nZXRFbGVtZW50QnlJZCgnYXVkaW9fcGxheWVy Jyk7CgogICAgLy90cmlnZ2VyIHByb21wdCB0byBhbGxvdyBhY2Nlc3MgdG8gZGV2aWNlcwogICAg bGV0IHN0ciA9IGF3YWl0IG5hdmlnYXRvci5tZWRpYURldmljZXMuZ2V0VXNlck1lZGlhKHthdWRp bzogdHJ1ZX0pOwogICAgc3RyLmdldFRyYWNrcygpLmZvckVhY2godHIgPT4gdHIuc3RvcCgpKTsK CiAgICAoYXdhaXQgbmF2aWdhdG9yLm1lZGlhRGV2aWNlcy5lbnVtZXJhdGVEZXZpY2VzKCkpCiAg ICAgIC5maWx0ZXIoZCA9PiBkLmtpbmQgPT09ICdhdWRpb2lucHV0JykKICAgICAgLmZvckVhY2go KGQsIGluZGV4KSA9PiB7CiAgICAgICAgbWljczEuYWRkKG5ldyBPcHRpb24oZC5sYWJlbCwgZC5k ZXZpY2VJZCwgZmFsc2UsIGluZGV4ID09PSAwKSk7CiAgICAgICAgbWljczIuYWRkKG5ldyBPcHRp b24oZC5sYWJlbCwgZC5kZXZpY2VJZCwgZmFsc2UsIGluZGV4ID09PSAxKSk7CiAgICAgIH0pOwoK CiAgICBidG4xLm9uY2xpY2sgPSBhc3luYyAoKSA9PiB7CiAgICAgIHdpbmRvdy5zdHJlYW0xID0g YXdhaXQgbmF2aWdhdG9yLm1lZGlhRGV2aWNlcy5nZXRVc2VyTWVkaWEoe2F1ZGlvOiB7ZGV2aWNl SWQ6IG1pY3MxLnZhbHVlfX0pOwogICAgICBwbGF5ZXIuc3JjT2JqZWN0ID0gd2luZG93LnN0cmVh bTE7CiAgICAgIHBsYXllci5wbGF5KCk7CiAgICAgIGNvbnNvbGUuZXJyb3IoJ0ZJUlNUIEJUTjon KTsKICAgICAgY29uc29sZS5lcnJvcignU1RSRUFNMScsIHdpbmRvdy5zdHJlYW0xLCB3aW5kb3cu c3RyZWFtMT8uZ2V0VHJhY2tzKClbMF0pOwogICAgICBjb25zb2xlLmVycm9yKCdTVFJFQU0yJywg d2luZG93LnN0cmVhbTIsIHdpbmRvdy5zdHJlYW0yPy5nZXRUcmFja3MoKVswXSk7CiAgICB9Cgog ICAgYnRuMi5vbmNsaWNrID0gYXN5bmMgKCkgPT4gewogICAgICB3aW5kb3cuc3RyZWFtMiA9IGF3 YWl0IG5hdmlnYXRvci5tZWRpYURldmljZXMuZ2V0VXNlck1lZGlhKHthdWRpbzoge2RldmljZUlk OiBtaWNzMi52YWx1ZX19KTsKICAgICAgY29uc29sZS5lcnJvcignU0VDT05EIEJUTjonKTsKICAg ICAgY29uc29sZS5lcnJvcignU1RSRUFNMScsIHdpbmRvdy5zdHJlYW0xLCB3aW5kb3cuc3RyZWFt MT8uZ2V0VHJhY2tzKClbMF0pOwogICAgICBjb25zb2xlLmVycm9yKCdTVFJFQU0yJywgd2luZG93 LnN0cmVhbTIsIHdpbmRvdy5zdHJlYW0yPy5nZXRUcmFja3MoKVswXSk7CiAgICB9CiAgfQoKCiAg cnVuKCk7Cjwvc2NyaXB0Pgo8L2JvZHk+CjwvaHRtbD4K
