when i tried this, the sound file albeit mp3, deliberately takes long, and never shows up as an option. I used to be able to do this back then, as i once made horror story on here with sounds, images, and all the hyperlinks were fine. So it leaves me to wonder if everything else works, whats wrong with sound?

PS: I retried it, and now its giving an error 404. Honestly, this is annoying me because it shouldnt be this hard. i like adding sound to these stories so you feel more in the moment, or have it be a product of ASMR for your enjoyment.

Could you be a little more specific? Is it a gamebook or textadventure? Online or offline version? Is it a problem of uploading the file or playing the sound? Where do you get the error 404?
