Description Daniel Gjörwell 2022-12-02 05:22:07 PST 
WebKit on iOS treats the duration argument to AudioBufferSourceNode incorrectly when the node is set to looping.

A simple example can be found here

https://jsfiddle.net/DanielGjorwell/x75uavL3/14/

Steps to reproduce:
1. Load the link above on iOS Safari 15 or later.
2. Once enabled, press the PLAY FROM OFFSET button a few times.
3. Note that sometimes the sound fails to play.
4. If on the other hand, you press PLAY FROM START, the sound will always play.
