Hello, I just got the "No Audio Output Device is installed" message for the second time. I can't remember what i did last time to fix it, but I've tried everything that people have suggested on multiple threads concerning this. It was literally working
last night as i was listening to music, today when i turned it on it said i had no audio output installed. I have an HP Pavillion dv9500. I upgraded from Vista Home 32-bit to Windows 7 Pro 64-bit, but never had a real problem until now. I tried to find the
driver on the HP site, but the driver didn't work. I've even tried to restore my computer to a week ago when i got a system update, but it keeps failing.There is also an exclamation mark on the Coprocessor under Other Devices in the device manager, but i have
no idea what it is, and my Sound, Video, and Game Controller section pulled a Houdini on me. Does anyone have any suggestions?
