DELL LAPTOP NO SOUND FROM SPEAKERS OR HEADPHONES HOW TO

Installing a sound card in a standard desktop is not difficult-it has basically the same steps as a graphics card installation-and there are many models available for $50 or less. They also use dedicated, high-quality components to output pure sound in digital and analog formats. Discrete sound cards arenвЂ™t as widely used as they used to be, but their PCI connections are separate from the motherboard. (If multiple headphone jacks are present, plug it in to the green one.) Whichever youвЂ™re using, try the other to see if the unwanted sounds persist. Most full-sized desktop computers have one headphone jack on the front of the case for convenience, and another on the back for those who prefer a cleaner look. There are a few things you can do to change this:

This can cause a buzzing or whining sound in your speakers and headphones. This makes things cheaper and less complex, but without proper electrical shielding, it leaves the audio jacks vulnerable to interference from the CPU, graphics card, memory, and just about every other component in your computer. Most PCsВ sold today include an integrated sound card thatвЂ™s directly attached to the motherboard. If youвЂ™ve determined that your computer itself is the problem, youвЂ™re not alone.

RELATED: How to RMA a Defective Product Reduce Electrical Interference From the PC If, however, youвЂ™ve narrowed the problem down to your PC you have a few potential solutions. If the problem is in the cable and itвЂ™s not possible to swap it out, you may be able to repair it yourself, though this usually isnвЂ™t worth it for cheaper speakers. At this point you need to replace it, either with a new set or a repair or RMA if youвЂ™re still within the speakersвЂ™ warranty period. You might be able to isolate specifically which speaker is damaged by listening closely, especially if you have a subwoofer or an elaborate surround sound setup. If the speakers are the problem, itвЂ™s likely that theyвЂ™re damaged. The fix here is simple enough: just use a different cable, preferably one with a high-quality jack and better shielding. What youвЂ™re hearing is electromagnetic interference from your PC or other electrical devices in the room. Usually this means that either the connector on the endВ has some kind of physical defect causing a poor connection with the audio source, or the cable itself is poorly shielded. If you hear clearer sound with no interference, then the cable was the likely culprit. If the problems continue (and itвЂ™s possible to use another cable with your speakers or headphones), then try replacing the cable.

If you still hear the unwanted noises, your PC is likely to blame. You can perform the same test in reverse, too: get another set of speakers or headphones and plug them into your PC. Note that itвЂ™s perfectly normal to hear pops and buzzes as you disconnect the audio jack and plug it into something else, but if you continue to hear electronic interference even after plugging it in, you can rule out your PC as the problem. To see if the speakers are the problem, simply plug them into an audio source other than your PC-like a phone or an MP3 player. ItвЂ™s easy enough to nail down which part of your speaker setup is at fault. Broadly speaking, we can break them down into three categories: problems that originate from the physical speakers, the cable connection, and from the PC itself. Luckily, the most common issues are fairly obvious. There are dozens, maybe hundreds of explanations for unwanted sounds coming from your speakers.
