This might be helpful in gaining an understanding of HDMI and DVI issues.

There may be a compatibility matter associated with either the unit or the cable you are using.  Your PC may support the DVI standard rather than the full HDMI standard.  Study the URL above on this - about half way down the page.

Also, the HP is supposed to support AES/SPDIF digital out which your tv may or may not accept.

Please run separate audio cables (RCA type) between the output of the PC and the inputs on the tv.  You may have to use the analog headphone output for stereo audio if your particular PC does not support 5.1 digital.

Hope this helps get to the bottom of the problem. If not, let me know further.
