How can i get audio from my computer through my Tv Speakers?

I have a computer hooked up to my LG TV; the thing is I’m using a DVI to DVI cable with a DVI to HDMI converter on the end of it for the signal from my computer to my TV. I don’t believe that I can get sound through this cable though. I have hooked up an AUX to AUX cable, just headphone to headphone, into the port that coincides with the HDMI port on the back of the TV. Now the audio that gets transferred through will only come on in a different input. If I have the cable hooked into the HDMI 1 port, it will work but the audio will only be on HDMI 2, I have looked into changing this doing something with the HD output but that didn’t work, any suggestions to how I can make it so both these inputs work on the same HDMI input? - Thanks -
