Drum Machine - Failing Case 5 and 7 . Pls help

Used vanilla HTML , JS and CSS+fontawesome

Project Link : https://jindal-vivek.github.io/drum-machine/index.html

Javascript link : https://jindal-vivek.github.io/drum-machine/index.js

The project seems to be working correctly still it is not passing the cases?

For me only Q pad works on click…

Sorry for the late reply , but now only keys work but still test cases are not passing :frowning:

Could someone suggest a solution ?

as for #5: moving <audio> inside <button> and

    if (power) {
        event.target.querySelector('audio').play();
    }
  });

worked for me, i mean think it’s something about html structure and the way you select and play audio… didn’t experiment with 7 sorry, im too slow right now)
