OK Guys. I was using ESS es1969 sound card for my PC since my motherboard audio output has failed to work. Recently when I upgraded to win 7, my sound card also stopped working because it doesn't have win 7 compatible drivers yet. I heard from a friend that Graphics cards can be used as an audio output device too. I have nvidia GT 630. But I don't know how to use it(if possible) ? I have 5.1 channel audio system with 3.5 mm jack. pls tell me how do I connect it to my gt630. Are there any cable I need to buy for it ?And if this process is not possible please suggest me some cheap sound cards compatible with win 7 or alternate drivers for my old sound card ?
