Sound running through dvi ?

[JasonKnights]

Hi there I am putting a system together for a mates sons Xmas present. The bios on gpu (gtx560) won't let me enter the motherboards bios so I'm using a dvi lead (dvi to hdmi) instead of a hdmi. Thing is I'm getting the pcs sound through the tv? I thought dvi doesn't carry sound ?

he gtx560 has a HDMI slot on the card i was hoping he could just use a hdmi cable for his sound ad vision as its going on an lcd tv in his bedroom. however when i use a hdmi lead the picture does not come on until the windows screen starts. so i needed to go and buy another lead to set up bios features, ive just instaled a few games and was very suprised to hear the sound lol if i use the dvi slot the bios comes up fine though
