Hey Tylerv972,
You could run the hardware test on the computer and it should let you know what is working and not working.
Try to configure HDMI audio, first connect an audio or video device, such as a high-definition TV, to the
HDMI port on your computer. Then configure the default audio playback device as follows:
Right-click the Speakers icon in the notification area, at the far right of the taskbar, and then click
Playback devices.
On the Recording tab, click either Digital Output or Digital Output Device (HDMI).
Click Set Default, and then click OK.
If the troubleshooting does not help resolve your issue, I would then suggest calling HP's Technical Support to see about further options for you. If you are calling within North America, the number is 1-800-474-6836 and for all other regions, click here: click here.
