Why is there no sound on my computer s stereo?

It may be caused by the following reasons: a. The card is not properly inserted, the sound card is not closely integrated with the expansion slot of the motherboard, and it can be seen that the "gold finger" on the sound card and the reed of the expansion slot are misaligned. This phenomenon is common on ISA cards or PCI cards, and it is a common fault, and finding a way to get the sound card plugged in can solve the problem.

b、The input end of the active speaker is connected to the speaker output end of the sound card,The active speaker should be connected to the line-out end of the sound card,The signal it outputs has not been amplified on the sound card,The noise is much smaller。 Some sound cards have only one output, whether it is line-out or speaker depends on the jumper on the card, the default method is often speaker, so if necessary, you have to unplug the sound card to adjust the jumper. c. The version of the installed sound card driver is not good, you may use the driver that comes with the system, if so, it is best to install a special sound card driver.

If you have installed the drivers that come with Windows, you can select "Control Panel System Device Manager Sound, ** and Game Controller", click on each sub-device, and select "Properties Driver Change Driver Install from Disk". Insert the disk or disc that came with your sound card and install the manufacturer's drivers.

Take a look if there is no sound card installed, right-click "My Computer" - Properties "-> Hardware" - >Device Manager", and see if there is a question mark in the pop-up window of "Sound, ** and Game Controller"? If there is, the sound card driver is not installed, and if there is no question mark, it is something else. You can go to the next universal sound card driver on the Internet and install it,

You can do this in the Control Panel under "Sound, Voice, and Audio Devices", and in the "Volume" tab, put a checkmark in front of "Put the volume icon in the taskbar". If that doesn't work, check if there is an audio device in the "Audio" tab, if not, the driver is not installed or missing, and you need to reinstall the driver.

Fix it, or check it again.

The solution to the failure of the host built-in speaker is as follows:

1. When the built-in speaker of the host is faulty (abnormal noise or no sound), it is recommended that you connect the headphones to test and confirm whether the headphone output is normal. If the sound of the earphone output is normal and the built-in speaker of the host is abnormal, there may be a problem with the built-in speaker of the host, and it is recommended that you report the machine for repair.

Note: Split desktop PCs generally do not have built-in speakers.

2. If you connect the headphones for testing, the sound of the earphone output is also abnormal, it is recommended that you reinstall the sound card driver.

3. After installing the sound card driver, if the problem is solved, it is possible that the fault is caused by a problem with the sound card driver.

4. After installing the sound card driver, if the problem is not solved, please consider restoring or reinstalling the system after backing up the data, or report the machine for repair and let the service station engineer help you detect and repair.

1 All 1: Software issues.

Although the sound control program is not easy to be damaged, it can cause the speaker to not sound due to the accidental operation or inadvertently deleted some important files in personal use, the unfamiliar operation of the optimization master software that causes the audio program to be deleted, so that the audio cannot be started normally, and the audio control program ends artificially after ending the unfamiliar process. However, this kind of problem is simple, take the driver disc provided with the computer and reinstall the audio driver, and the problem will be solved.

2: Hardware issues.

If the speaker is used for too long, the internal circuit will deteriorate, or the artificial movement and collision will cause its poor contact, and it will not sound.

But the problems are easy to solve, first check the sound connection problem, to ensure that it is still not good after the good condition, just install the driver, if the driver is installed is not good, it is time to change to a new one.
