Any way to play a sound alert on a Tablet?

I’ve got a rooted Amazon Fire tablet on the wall and I can send TTS to it no problem (works reliably) but I’ve not found a way to play sound files on it (like a security alarm siren). Anyone got this working? Fully Kiosk is on the app. I use HTTPS because of DuckDNS so not sure this would work as I don’t think Fully would be able to access the file…? I have tried it, by the way.

You could try this:

It worked! Thanks
