In device manager there is a yellow mark by MPU-401 compatable mini device. Under properties it says this device cannot find enough resourse it can use.(code 12).If you want to use this device, you will need to disable one of the other devices on this system. I have no idea what to disable. I've done every thing in the troubleshooter, still no sound. Please help me.

You have a Problem with your sound card or Sound Cards (if you have installed a PCI sound card in addition to an onboard one if the Computer is a Desktop PC) "I've done every thing in the troubleshooter" Unless you spell out what exactly you have done, it will be hard to say what you need to do. The best way to get some good help is to give us details about the system that is having the problem. From your specifications, it is not even clear whether you have a Laptop or Desktop Computer made by Dell. There is no information as to what family and series it belongs. These are details very readily available to you as they are often clearly displayed on the Computer case/cabinet. M

I have a windows xp home desktop pc and an on board sound card. Is there any other information I need to include?

As posted before name of the PC or name of Sound Card or Name of Motherboard are needed. If it is a Brand Name PC, what is the EXACT name of the Computer? If it's a custom built PC, then post the Exact Make, Model and Version of the Motherboard. M
