No sound when sharing an App

Hello,

I am using Zoom on my Android phone (Samsung Galaxy S21 Ultra 5G).

On sharing screen, I oppend in my Cellphone an App called Youcut.
When I share the screen during a meeting using Share → Screen and enable Share device audio, the participants can see the App but cannot hear any sound.

Here are the details:

• Android version:  Android 15

• Zoom app version: 6.65.34303

• I have already given microphone permissions and enabled Share sound.

• The media volume is turned up and no Bluetooth audio device is connected.

• The issue occurs whether I am connected via Wi-Fi or mobile data.

Could you please advise if there is any known issue with device audio sharing on Android, or a specific setting required for Samsung Galaxy devices?

Thank you,
Boaz Oren
