Hey david4848,
Thank you for your reply, I am glad to try and help you resolve this.
Here are some troubleshooting documents that may assist you,Increasing or Decreasing the Volume Distorts the Audio (Windows 8), and No Sound from Speakers (Windows 8). Your system comes with Beats Audio, so I am also including Beats Audio Console (Windows 8) and Beats Volume Control Direction Setting Does Not Work. I am not sure if the Beats volume is working or not, so I included it , just in case. Please let me know if this has helped.
