            Bug ID: 248658
           Summary: AudioBufferSourceNode.start with duration fails
                    sometimes
           Product: WebKit
           Version: Safari 15
          Hardware: Unspecified
                OS: Unspecified
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: Web Audio
          Assignee: webkit-unassigned at lists.webkit.org

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.
