I installed a good sound card driver move, there are small loudspeakers, the Device Manager, there is no sigh …

first look at the situation there is no problem with the audio line, if there is no problem, then it may be the wrong driver.generally sound card If not drive models will not sound.Dxdiag run the sound card can view the information.Try two situations:First, carefully checking line, I encountered one person is not sound, he found the last speaker of the off-line, Hao Jiuxing play, it encountered, the earphones.

Second:not necessarily looking at driver installed, there are small speakers, equipment manager, nor an exclamation point on that drive is installed Correct.Soundmax a lot of the sound card, sound card driver realtek can also be installed, there is also a small speaker, Device Manager, there is no exclamation mark, but no sound.Soundmax In other words, and the sound card driver realtek interchangeable , But no sound.

You that failure often comes in the package, some of the universal system, in order to support more hardware, integrated drive too much, I will install this failure.

recommended if you install the driver realtek, soundmax replaced, or vice versa.

I guess your sound card is one of the two.I also have a home situation, how Xiu Xiu is also not good , You find an expert to make it!
