No audio on my new build :(

[Ineed2know]

Hi guys,
I've recently build a pc and I have no audio out. I can't figure out why. The mobo is a Nvidia GEFORCE 7050 M-M by ECS Elite Group. The processor in AMD. I'm going out trought the AC3 connection. But is it the right one? I tired the other one and nothing. If anybody has any ideas, please let me know. Thanks.

Alex.

Did you install all the motherboard drivers?

To check the all hardware working status : Right click on My computer icon > go to manage > Device manager. Here you can check the sound driver status if you are looking here "Yellow ?" mark then you have to installed right driver for sound.

I thought I had installed all the drivers. Hammer, I did what you suggested (thank you so much) and there is a yellow question mark for the PCI. It seems the drivers for the audio are there. I don't use the PCI card, could the fact that I don't have the drivers installed for the PCI card interfere with the audio?

Thanks for the help

What PCI card is it?

[Ineed2know]

There is no PCI card, or any cards in that computer. There is a built-in video card to the mobo, that's it.

Then you have an onboard component that uses the PCI bus which you don't have the drivers installed for. Exactly WHAT does it say and what category is it under?
