What is an audio driver?

An audio driver is a driver on the computer, mainly dealing with sound cards, audio decoders, external optical drives, etc. To make these things work properly, your computer must be loaded with a driver named audio device driver. Its main role is to enable you to listen to music, watch movies and play VCDs on the computer.


When installing a sound card, you need to pay attention to the corresponding manufacturer's brand as well as the model number of the sound card chip.

Some major sound card manufacturers:

A3D /Abit /Acorp /Add Addonics /ALi /Amax /AMD /Aopen /APAC /ASIO /Diamond /DIYEDEN /Eagle /Ensoniq /ESS /Microsoft /NVIDIA /Octek /OOAOO /OPTi /PcChips /Precision /Philips /Pine /Razer /RealWorld /Rta /SigmaTel /IgmaTel /Soyo /T&W /Taiyanfa /Sunflower /TM

How to detect whether the audio driver is installed or not:

Usually, you can use the computer to directly play an audio or a video, and then check the speaker to see whether the computer can make a sound or not.

A few reasons for computer sound failure:

1. Power supply failure

The sound card is a relatively sensitive device to the power supply, so a good pc power supply is helpful for the improvement of sound quality. When combined with a poor quality power supply, the speaker may sound unclear, especially for those sound cards that carry a power amplifier circuit. A little fluctuation in the power supply will cause noise or unclear sound. If your computer has similar situation, you might need to consider changing your old power source to a new one.

2. Realtek audio manager is not set up properly.

Take Win10 as an example: you need to test whether Realtek audio settings are correct or not. Click the "control panel" item, then click the "Realtek Manager" item, then click the "jack settings", and lastly go back to the desktop to play a song to test. The verifying steps for Win7 and Win8 systems are similar.

3. Output devices or interface connections are abnormal.

I: Replace another new headset or headphone to test. If the sound is normal, then the problem must be in the original output device. Replacing the output device can solve the problem.

II: Check whether the audio device interface and the output port of the chassis (generally the green port) are properly connected. If the front port is invalid, you can use the port behind the PC.

4. The hardware itself is physically broken.

For the damaged hardware, it is recommended to go to the repair store for repair.
