Review on SEDNA SE PCIE SC 10 Quality Channel CM9882A by Carlos Abood

I bought 2 of these cards for the 2 computers I use. Both with Windows 7 64 bit. Works great on a computer. Does everything it's supposed to. Another computer is not very good. On the second computer, I only get sound from the center analog output. I can toggle outputs and inputs on the control screen but nothing happens. I don't have an optical input and I can't switch inputs even though the screen says they are active. I tried the card on a working computer, the card works as it should. I also installed it on my old Windows XP computer and encountered the same problem. That tells me there is a problem with the driver. Something in the drivers is not compatible with one of my Windows 7 and XP computers. I have contacted the seller to solve the problem and am waiting for a response.
