Suggest you run an analoq (standard) stereo audio cable from your pc (headphone output) and connect this to the red and white rca / phono connectors (audio) on the TV set. The lead that connects to the headphone socket will have the small miniature connector commonly used on a set of headphones with the miniature socket.
Connect the DVI cable, if you use the HDMI adaptor you might need to go into your tv menu and assign the analoq audio input to the hdmi input. However this might not be possible because the tv assumes that the hdmi input is carrying video/audio and therefore why would you want to assign analog audio
DVI connector never carries audio.
You might want to adapt the DVI to 15 pin VGA connector instead as definitely VGA (15 pin connector) will ALWAYS use audio on the red and white sockets....however your tv may not have a VGA input connector.
I would need to see the input panel on your tv to recommend the best way to connect.
