Just putting here the reply/solution I’ve received for future people to see what i have done wrong and do not need to stress about it
Thank you support team!!!
Syrinscape Online is not a web player. Are you running both the Online Player App and the Master Interface Web page? The Master interface is designed to allow you to trigger the sounds, but the browser will not actually play them. For sound you need to be running the Online Player, which needs to be linked to your account. Sounds triggered in the Master Interface will then play through the connected Online Player.
We have put together a tutorial video that talks you through setting up Syrinscape online, which you can watch here; https://youtu.be/vfdider-rOQ
