Audio no Playing on embeded videos [youtube]

[goodmuyis]

I created an app with and used laravel-pwa which works well, but unfortunately when i decide to test embeded video, it plays well but the audio was muted. The youtude video was loaded using iframe embed.

=> I test the video on youtube/chome on my phone, audio came out => I tested it on previously app created with Andriod WebView, audio came out => the volume control did not fix the audio

Is there anything missing? kindly help
