Audio is not working on webview

Hello community !
I’m creating a webview app using this website .but When I tried to open it on webview, the audio function is automatically disabled, but the website is working fine on both mobile and desktop devices.

can anyone tell me how can I fix the issue ?

Are you using Samsung Android 11? It appears to be a known issue now. Even video does not work. I have issues with my webRTC apps now. Check this report: In Samsung Android 11 webview webrtc not access camera and microphone - Samsung Community
It’s probably not an issue with Kodular.
I hope they fix soon.
