iPhone SE (iOS 15.5) 1) Try to check microphone permission in iOS native code. 2) If the permission is granted, microphone indicator which is located in top of screen is on as orange color. 3) Start to capturing microphone using getUserMedia() and playing audio using AudioContext. 4) Volume of playing audio reduces as half of original volume. 5) Stop to capturing microphone 6) Start to capturing microphone using getUserMedia() and playing audio using AudioContext. (same as step 3) 7) Volume of playing audio is restored as original volume. Expected behavior : For Step 3~4, Volume of playing audio should be same as original volume. The first time I try to play audio(Step 3~4), it always plays the sound at a low level. Is there any solution or workaround for iOS 15.5? And I would like to know this issue is solved in latest Webkit version if it is known issue.
