Build a drum machine (some keys play, others don't)

I initially coded my app in vscode and locally all the tests passed. Howewer when I moved it to codepen, the test #5 and #6 fail. Some of the keys play and some don’t. I have been stuck on this for hours. Any help, pointers, feedback is appreciated.

Just replaced your sound url with working ones. Since audio url under “Q” works, put it for all of them and your tests will pass and will work. Problem is that servers from whom you getting your audios in conjuction with Codepen itself need time to respond and thus fails.
