this appears to be working but there is no sound. i get the message "failed to play test tone" when i click test in playback devices. I've been to countless forums and have found that many have had similar issues with various audio cards but i haven't found a fix for soundmax. windows update automatically downloads updates for this and then tells me that it is working when it isn't. I have even tried to use generic drivers (like realteks) to see if that would work. I've tried compatibility mode with no luck as well. Please help. Current Broken/non-funtioning Driveri : Soundmax Integrated Driver Version 18.104.22.16890 System : HP Pavillion dv4015cl OS : Windows 7 Build 7022.winmain.090115-1850 PS I may not be a computer technician or anything but I do have a fair amount of experience installing drivers and stuff so please assume that I have done most of things that I should have tried to troubleshoot if you are nice enough to offer me some advice. THANKS!
