This is driving me bananas! I have been at this all day. I firstly installed XP onto an older computer and the sound wouldn't work so I just bit the bullet and installed 7 on it instead, but again no sound. It is a fairly old Advent T9206 PC with a NVIDIA Graphics card installed. I have uninstalled the device downloaded loads of drivers. I just keep getting the same error "This device cannot start. (Code 10)" the PC is running amazingly apart from this. I had been using it to play with Linux distros and none of them had any issues with the sound. It won't even let me adjust settings or anything, just says "no audio devices are installed". I have even reinstalled W7 again and still the same errors. It is driving me crazy! Help!!
