It seems after a recent iOS update (13.1.3) a bug appeared with Safari and audio recording.
Because the MediaRecorder is not supported by Safari/iOS I use (some polyfill) getUserMedia for capturing and ScriptProcessorNode for recording. After recording is finished raw data is decoded to wav and then audio can be played. Until recently it worked.
Now I've discovered a strange behavior. The recording is finished successfully but I can't playback the result audio. Playback doesn't start and there is no any errors. It's seems like Safari can't play audio when device/context is busy with capturing or etc. If I minimize browser to tray and open after some time (~10 sec) playback is work well.
This problem can be reproduced here https://ai.github.io/audio-recorder-polyfill/
but this work fine https://kaliatech.github.io/web-audio-recording-tests/dist/#/test1 https://danielstorey.github.io/WebAudioTrack/index.html
Any help?
