HDMI hook-up problems

We have an LG37LC2D-UD (June 2006 model) that we are attempting to connect to a Dell Studios XPS with and Intel (R) Core (TM): 7 CPU running Windows 7 Enterprise (6 GB RAM, 64 bit os). We tried to connect the high speed HDMI cable through the NVidia GE Force 310 sound card on the desktop cpu. We have great video but no sound. We are stumped. Any help would be most appreciated.

I might be wrong, but...

the sound should come out of the computer sound card speaker connection. Your video card has DVI output and DVI don't have sound as hdmi have.

Is PC in HDMI default

Not being an expert on sound cards
If your sound card has the HDMI connection, it seems it should support some form of HDMI video and sound. I may be missing what you are trying to do; but have you checked to make sure you have the HDMI output selected, under audio(in tools). It is under the playback tab for 7 home edition. If you have the default set for speakers on the PC, you likely will not get any audio on the HDMI port; instead, it will pass through the external speakers of the computer(if connected). Perhaps I am under simplifying thisHappy
