Audacity won't playback my voice!

[EleFlameMax]

So, I open up Audacity. I click the record button, record my self singing, and then click "Play":



I clicked "System", "Preferences", "sound" to test if sound capture is working properly. I tried it, and got the following message:



It's important to note that I got brand new speakers, and when I plugged them in, they worked for a little bit, but then stopped working. They're on, and everything is connected fine, but for some reason they won't play any sound. I've been using headphones ever since, and they've worked just fine.
