Changsoo-UTop commented 3 months ago

Hello. I'm using gree webview for showing Youtube or web E-book contents and It worked great until Android 13. but I tested in Android 14, It worked something weird.

  1. Play background music in Unity.
  2. Open webview with Youtube URL or internal E-book contents on Unity.
  3. Do some interaction to play sound. (Touch unmute button on Youtube web page or touch speaker button for narration on E-Book contents.)
  4. Close webview.
  5. Unity sound is not work. (But It's playing. just can't hearing.)

What can I do for fix this bug?

Thank you.

It only happens in Android 14. and... It could be Audio Focus issue on Android 14..?

Thank you for the archives and the movie. I was able to reproduce the issue on my devices; one was Headwolf FPad5 (Android 14) and another was OSCAL Pad8 (Android 11).

As you mentioned, the cause seems to be related to Audio Focus, but it doesn't depend on Android versions, instead, it depends on Unity versions. The easiest workaround is to turn "Other Settings/Configuration/Mute Other Audio Sources" off.

Oh.. I didn't thought test with "Mute Other Audio Sources"... Thank you so much for testing and answer!
