Hi all, I have an interesting problem that I have not run across before. I am trying to get audio (sound) output from our Dell PE 840 running Windows 2008 R2 Enterprise. I have tried a myriad of USB sound cards all with the same result. If I plug in a sound card that I have never used before into the Dell it will start working and I can get Narrator to work fine. Now if I reboot the computer and try that same USB sound card it won't work again and never will. This is the same results as with all sound cards I have tried. I have heard something about Win 2k8 not allow the loading of non signed drivers at boot up. Is this true and how can it be fixed? If not does anyone have any suggestions as to what to do to make this work? I am really pulling my hair out on this one. Tia Frank
