Finally figured it out! In case anyone else has/had a similar problem, this is what I did. 1. Open the Control Panel → Sound → Speakers → Advanced 2. Un-check "Allow applications to take exclusive control of this device" 3. Open Volume Mixer 4. Unmute Chrome 5. Voila!
Perhaps the digitizer is broken. You can get a replacement for a decent price. I'm not a proffesional though, so you should definitely have it looked at by one before making any purchases.
