Trimmed Audio Didn't Work in PowerPoint Browser

Hello Everyone

I don't know if anyone encountered this problem. But my trimmed audio that worked perfectly fine in PowerPoint desktop app doesn't work properly when I opened it with the PowerPoint browser. The audio file started playing from the beginning when I clicked "play" button. In the desktop app, the audio played the trimmed part which was how I wanted. In the browser version, the audio file played the whole thing.

Does anyone know why it's happening? I'd be appreciated if you can tell me how to fix it. Thanks!
