How do I fix sound issue in ios build for uploading on app store?

Hi everyone,

I’m currently trying to upload my Construct-based game to the Apple App Store using Cordova (iOS build), and I’m facing a persistent sound issue on iPhone.

The game runs in the browser, even in simulator & real iPhone device but audio is not playing at all .

Here’s everything I’ve already tried so far:

1.)Removed .ogg files

I removed all .ogg audio files and kept only .m4a (since iOS doesn’t support .ogg properly).

2.)Audio Unlock Events (Construct Event Sheet)

Added touch-based audio unlock events like:

On first user interaction (touch/click) → play a silent sound

Ensured audio context resumes on user input

3.)Re-exported Project Multiple Times

Clean export from Construct after making changes

Made sure no leftover old files remain

4.)Tested Different Build Methods

Tested via simulator and real device

Issue mainly appears on real iPhone

5.)Checked iOS Settings

Device is not on silent mode

Volume is up

Permissions seem fine

6.)Cordova / Build Setup

Using Cordova iOS build

All required platforms and dependencies installed (Node, CocoaPods, etc.)

7.)WebView Related Concern

I read that sometimes WKWebView / WebView policies on iOS block audio autoplay

Not sure if this is causing the issue in my case

My Questions:

Is this a known issue with Construct + Cordova on iOS?

Do I need to manually configure something related to WKWebView audio policies?

Is there any additional plugin or setting required for audio to work on real iPhones?

Am I missing any important step for unlocking audio properly?

I’ve been stuck on this for quite some time now, so any guidance would really help.

Thanks in advance 🙏

Thanks a lot bro, problem is fixed & the cause is same .m4a file type, basically its a old game & is containing .m4a files
