Hello! Thank you for reaching out! I can see how using the multiroom app will be very help. You should be able to use the steps below to get your soundbar set up with the app.
1. Plug the speaker you want to connect into a power socket
2. Open the Samsung Multiroom app on your smartphone
3. Tap NEW SETUP
4. Select the speaker that you want to connect
5. Check that the speaker is plugged in and within range of your Wi-Fi network, then tap Yes
6. Once your speaker is found, it will automatically connect to your Wi-Fi network. If your Wi-Fi is password protected, enter your password when prompted
7. Tap Connect
8. To finish connecting your speaker, tap No
Please note: if you wish to connect additional speakers, tap Yes instead. This feature is only available on Android devices. The steps for adding additional speakers on iOS devices can be found in Adding a speaker
