No audio after installing new graphic cards
Hello everybody, I've just reinstall a new graphic card (Gigabyte GeForce GT640 2GB) on an old windows XP compaq desktop PC to make it work again because the graphic card broke up. Now the problem is that my speakers doesn't emit any sound, systems sounds too. I've read some thread which suggest to disable the HD audio and select speaker as primary plugin, but when I open the audio settings it's shown that there is no audio plugin installed, speakers works properly, I've checked it on another computer. What do you think? It's audio card problem or what?
Thanks
