Audio playback (HTML5 elements, triggered by a button click) doesn't play at all inside my installed Android app. The exact same page, opened in Chrome on the same Android device, plays the audio correctly. I've tried: clearing app cache, clearing app data, reinstalling the app, updating Android System WebView, updating Chrome. Nothing has fixed it. My app is "English Passport" (co.median.android.eezxdaw). What could be blocking audio playback specifically inside the wrapped app?
