Thank you for your feedback - I have it working on iPadOS 26.5 (Chrome and Safari). The browser auto-play policy does require some interaction with the page before it will play (so the first key press is often mute, but should sound after). There is a button on the control bar to enable sound explicitly. I will look for more instances (not to ask the really obvious question, but do you have sound turned up or a bluetooth connection you're not aware of by any chance?). Thanks again
