Part 3: How to Recover Lost Data from Dell?. Part 1: Why is the sound not working on my Dell computer?. Refer to the motherboard or computer's documentation to determine if your computer is set up this way. Some motherboards do not have an onboard speaker and instead use a computer case speaker that can be removed to disable the speaker. Refer to the motherboard's documentation to determine if your motherboard has such a jumper, and how it should be set. Many motherboard manufacturers have jumpers that, when jumped or not jumped, enable or disable the onboard speaker.Īll motherboards are different. If the steps above don't disable the internal speaker (i.e., there's no Non plug and play Drivers section), the internal speaker can be disabled by the motherboard jumpers. If you want to permanently disable this device, under the Startup type, select Disabled. On the Driver tab, if you want to temporarily disable this device, click the Stop button. In the Beep properties window, click the Driver tab. If you do not see a Non plug and play Drivers section in the Device Manager, skip to the Motherboard jumper section below.
