You need to be running build 10.0.10586.0 first. You can update to the latest build by re-flashing your current SD card. These docs will get you there: http://ms-iot.github.io/content/en-US/win10/RPI.htm

@Brandon:Glad you got it working! I always have a ton of fun when I play around with tools like Soundation. One thing I didn't demo is that you can import your own wave files to use on the Audio channels. Adding tools like sfxr and Audacity as well as sounds from freesound.org and pdsounds.org can really make it interesting!
@Brandon:Not sure what the problem might be. Have you tried any of the other synthesizer options, and if so, do they make sound?
