On iOS (iPhone or iPad) the following behaviour happens: when both an HTML video element and an HTML audio element are playing on a page, and the video source ends, and the video source is programmatically forced to play again then the system will automatically pause the audio. See following stackblitz project for a sample: https://stackblitz.com/edit/ios-audio-paused-on-video-playing?file=README.md Steps to reproduce Feel free to try with both another audio and video source, here limited by the available space in Stackblitz plan. On an iPhone/iPad device or simulator, in Safari: browse to index.html when on iPhone, press iPhone Load to force preloading video. Not needed on iPad press Play to start playing both audio and video wait until clip ends and then restarts from 0:00 Expected Audio should keep on playing and eventually loop. Actual When clip restarts from 0, audio is put to pause by the system. Further details This does not happen e.g. on Mac Safari nor on another device/browser. Also, some alternative scenarios: when HTML video element has the muted attribute, the issue disappears and audio is not paused when HTML audio element is replace with Web Audio API, the issue disappears and audio is not paused
