Pomodoro clock - cannot pass audio test

I’ve used react and redux to solve this challenge, but for some reason I cannot pass one audio test.

28/29 passed:

1. When a countdown reaches zero (NOTE: timer MUST reach 00:00), a sound indicating that time is up should play. This should utilize an HTML5

Timer has reached zero but audio is not playing while it should.: expected true to be false

Any ideas?

I haven’t done this challenge so I’m just speculating here. Your clock definitely goes down to 0, and I do hear the beeping, but the beeping doesn’t start until almost a second after it reaches 0. Maybe this delay is fooling the tests?
