react-native-sound VS react-native-keep-awake

Try searching GitHub issues with the "loop" keyword. There's one in there where infinitely looping short sounds causes gaps. Maybe as a trouble shooting step try playing a longer mp3 to see if the behavior changes. https://github.com/zmxv/react-native-sound/issues/640

I am building a running app that shows a timer. When the timer reaches 0 seconds a sound is played. I use React Native Sound for playback. I use an interval on componentDidMount for counting the seconds:

I found https://github.com/zmxv/react-native-sound but it's lacking setPitch on iOS (maybe because they are not using AvAudioEngine), is there anyone have tips regarding this? I don't have swift experience

If that is correct, you have not installed `react-native-sound` properly. There is actually a note about this in the installation instructions on the repo: https://github.com/zmxv/react-native-sound#installation (at the bottom)

componentDidMount() { this.recalcTotalSeconds(); KeepAwake.activate(); this._interval = setInterval(() => { this.step(); }, 999);} It works nicely as long as the phone is unlocked. When the phone is locked the interval is not fired and the sound is not played. As a first measure I uploaded a version with Keep Awake that prevents the screen from locking. I am looking for a battery-friendly solution.

React Native for Web is compatible with many native modules that ship with React Native: Button, Views, TextInput, etc… will be automatically mapped to their web counterparts correctly when imported from react-native. Unfortunately, using other external native libraries like react-native-sound or react-native-keep-awake can be a bit hit-and-miss because many native functionalities are not available on the web.
