Tw33k posed a good question, answer that one and also do this.
Go to the Playback Devices again, select your speakers... on the bottom left, there is a button labeled "Configure" open it and see what the setting are. It should be set to Stereo.
There's also one other oddity than can happen with USB speakers. They sometimes shut down. So, try a machine restart, also try setting the Default speakers to something other than USB, then re-selct them as the default device.
