BIOS setup failure causes WIN7 noise to run

WIN7 system running when the noise situation caused by a variety of reasons, today's small series to introduce to you the cause of WIN7 noise is an important reason for the operation of-bios settings.

An ASUS X85s43se laptop (ALC269) that was bought a few days ago has recently been upgraded to a Win7 system with a cacophony of sound as long as it is in the internal or external headphones.

Asked Asus customer service, replied that the driver is definitely a problem, but the author replaced Asus official website to provide the latest Win7 sound card driver still can not solve the problem. Later, the version of Windows 7 was installed on another laptop, but it played normally, and there was no noise problem after swapping back to the Windows XP system.

Reluctantly, the author carried out the last Test, unconsciously downloaded the latest BIOS version and a refresh, the result of the problem solved. It's great to listen to music and watch movies.

Next, the author through this method and successfully for friends and colleagues of the notebook to solve the problem of Win7, it seems that the voice of the Notebook is not only related to the sound card driver, and the motherboard BIOS version of the new and old also have a great relationship. So I write down this little experience, I hope to more notebook users to play a role in reminding.
