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.
