Twine Harlowe: Audio Playing, but Can't Hear

I made a game in the Twine online editor in Harlowe, and I used the Harlowe Audio Library to add audio. However, I can’t hear the audio in Harlowe, nor when I publish the game to a file. I tested the audio using an “if” that would print some text if the audio were playing and it did print the text, confirming that the audio is in fact playing. I also tried several browsers, confirming that this isn’t something on the browser end. Why can’t I hear my audio, and how can I make it audible? Thank you!
