There is a problem with the AC97 sound card, what is the difference between the AC97 and the HD soun

Try turning down the sound card option in the Control Panel.

The AC97 is the sound card that was integrated into motherboards in the past. The current HD is better, and it is digital audio.

The solution and detailed operation steps are as follows:

1. In the first step, open the "Control Panel" option of the start menu, see the figure below, go to the steps below.

2. In the second step, after performing the above operations, select the settings icon display, and then click on the audio option, see the figure below, and go to the steps below.

3. In the third step, after performing the above operations, point to the correct yellow folder, see the figure below, and go to the steps below.

4. Step 4, after performing the above operations, check the following options, see the figure below, go to the steps below.

5. In the fifth step, after performing the above operations, click the "OK" button, see the figure below, and go to the steps below.

6. In the sixth step, after performing the above operations, you will find that the sound can be emitted from the front and back of the computer, see the figure below. In this way, the problem is solved.

Caused by an incorrect setting. Refer to the following below:

1.First select Enter Start, and then enter the control system panel as shown below.

2.Next, select the settings big icon to display and click on the audio as shown below.

3.The back road starts pointing to the correct yellow folder, as shown in the image below.

4.Then select the Disable item back to the checkbox, as shown below.

5.Then start selecting and click OK as shown below.

6.Once you've set it up, you'll find that the front and back of the computer can make sound.

The front port of the chassis in the market is generally compatible with the standard, that is, the front port can be compatible with different defined sound card input standards at the same time, in this case, only by selecting the corresponding standard mode can the front interface be used normally, such as the HD sound card is selected as AC97 mode, and the VIA sound card needs to turn off the front detection to work normally.

You should have AC'97 (another one might be called HD Audio) in the BIOS, so the driver settings are the same here.

Go into the BIOS and look for the option settings, this option is probably in the OnBoardDevices of the BIOS or in the Advanced-ChipSet-SouthBridge, here is an example.

Select HD Audio as you should

Different motherboards may have different BIOS options, so look for them.

HDMI interface? HDMI needs your monitor to support it, and then plug the speaker into the monitor.

In old cases, the front audio cable generally only has an AC97 plug.

New chassis, generally HD audio plugs.

There are a large number of over-products in the middle, both AC97 and HD Audio, open the case to see if you can replug it in.

Different hardware requires corresponding drivers to work properly.

If your sound card must be installed with the AC97 front headphone jack to have sound, it means that your sound card is AC97.

In order to determine this problem, you can install it in the next driver wizard test.

BIOS is a CMOS chip control program solidified in the motherboard to control the boot check of the computer.
