Use the driver life check the driver update to see if there is a sound card driver installed, and the driver is really not good, go to the repair shop to see if there is a problem with the hardware.

Enter the Windows system, insert the system disk of your own Mac OS X (it must be a system disk, not that application) Double-click the optical drive to reinstall all the drivers in the disk (it is automatic).

Is there a mounted drive?

It seems that the hardware of Mac is very different, and Win7 may not have all the native drivers.

Click on the lower right corner to show the hidden icon, that is, there is a small triangle upward, and there is a gray prism inside, click on it to appear Boot Camp Control Panel, click on it, select the keyboard, and then remove the checkmark and click on the application (the premise is dual system).

Description: Win7 does not correctly recognize the sound card, and install the driver, can be solved with the help of third-party software, take the driver wizard as an example, the operation is as follows:

win7 is too advanced,I don't know your sound card,In other words, your sound card is too old,The old win7 doesn't know it。

PS: Actually, Win7 is a 64-bit operating system, XP is 32-bit, so it should be said that your sound card is 32-bit normal, 64-bit is not supported, I think it should be like this.

Because Apple laptops don't have a sound card driver:

Mine has also had this situation、Go to customer service to install the original driver。

I'm in the same situation, solving

This is due to the fact that there is no driver corresponding to the sound card under win7,You can do it with the help of software such as driver wizards,The operation method is as follows:

Win7 I tried it before and the interface is beautiful. However, there are still many software that are not compatible. Or switch back to XP. However, there has been no such phenomenon.

You start by taking a closer look at your sound output line. Hehe. It is very likely that the problem here is that you should take a closer look inside the sound management to see if it is muted.

Then try to update the sound card driver, pay attention to find the one marked as win7, and it is divided into 32-bit and 64-bit.

If you can't try to change the sound card, you can't honestly install it back to XP.

It is not recommended that you install Windows 7 at this time

There is no sound because you don't have a driver installed.

And the official driver has not yet come out.

So it's best to wait for the official version to be released, and Apple will also release the corresponding driver.

The sound is gone, so use a toothpick to get it on the headphones. The red light went out. Just ko!!

There is no sound under the apple computer win7, and the headphone jack lights up red, which is a short circuit caused by pulling out the headphones. Use the headset head, toothpick or paper clip to touch the contact point inside the earphone, and then press the keyboard sound switch a few more times, the circuit is turned on and the red light is off, and the sound is KO !!

Focus on checking the driver and settings. But your Apple machine with Microsoft's system is not always very good.

If you can hear the headphones under the Mac system, then you can see if there is a problem with your output settings under Win, and then look at the driver.

Check the settings first, and if the settings are okay, change the headphones.
