I use a P5L-MX motherboard. I took my computer into the shop for a cleanup and reinstall vista due to a trojan virus being apparent. When I got it back, I had no sound at all. I had 5.1 surround before, which sounded great. Alas, no more. Vista informs me that HDAUDIO is working OK, but still nothing. I have everything plugged in properly. Can anyone please HELP me?

Dear "The Only Sol,thanks heaps for even answering my query, however, the guy at the fix-it shop assures me he did'nt open my case. I have to believe him, I think. He says all he did was uninstalled Vista Home Premium, saving my pictures and documents first. He did a cleanup of all the junk, and apparently getting rid of the trojan virus, (He explained that by doing this, the trojan disappeared and no longer registered at all). All I had to do was reload all of my programs, (Yeah,I know). But before I go ahead and do this, I'd rather have 5.1 surround sound back. The dumb thing about all of this, is Vista won't read my ASUS setup disk. What a nightmare. Thanks anyway Sol. regards Steve Dear "The Only Sol,thanks heaps for even answering my query, however, the guy at the fix-it shop assures me he did'nt open my case. I have to believe him, I think.
