Check your sound configuration to make sure your sound card is configured properly. I was having the same problem and noticed that my system had defaulted to using the HDMI output on my graphics card for sound rather than the sound card. After disabling the HDMI, and configuring the built in audio to 5.1 surround, it started working for me again.
