Hello,

This issue is related to the Emulator, if you run your application to the Android physical devices. You can hear the voice when video is playing.

Then I found emulator's sound is closed by default.

You need to press the top volume button underneath the power icon. Then click the three dots.

Next, click the settings, in this step, you can hear the clicking sound and set the media volume to the max.

After that, you can run your application to hear the video's sound.

Best Regards,
