How are you playing audio? Are you using a native plugin or web players? If web, you are going to run into issues especially with long playing audio.
The following native plugins are available that I am aware of:
- GitHub - mediagrid/capacitor-native-audio: Play audio in a Capacitor app natively from a URL/web source simultaneously with background audio and background play support. (I maintain this)
- GitHub - eduardoRoth/media-player: Native Media Player for Video and Audio with Fullscreen and Embedded mode.
- GitHub - capacitor-community/native-audio - good for quick audio sounds
- Audio Player Plugin for Capacitor - Capawesome
