l The horn has a rustling sound, but when you press the audio manager, it is gone, what is the probl

The sound rustle could be due to the following:

1. Contact reason, you can unplug all the audio cables of the audio, wipe it and plug it back in again to ensure good contact.

2 interference problems, it may be that the wires of the audio input are entangled with other wires, which will cause electromagnetic interference, that is, there will be rustling and other abnormal sounds, 3 It is also possible that the shielding layer of the audio cable is not good or broken, and it is OK to change the audio cable with *** point.

4. There is a foreign object, it may be some insect or something that has fallen into the stereo, stuck in the position of the drum, and the friction with the drum when it vibrates will also cause a rustling sound.

When the sound is rustling, the negative feedback of the internal power amplifier IC of the audio is caused by virtual welding of the feet or the virtual welding of peripheral components, and the reason is due to moisture or vibration. You can take it to a repair point to repair it, it doesn't cost much.

Look at the signal ground, the signal shielding, and the signal input and the 1m resistor.

It has nothing to do with the computer, it's the adjustment knob of the speaker that has a problem. The adjustment button is in poor contact when adjusting, and the current is sometimes large and sometimes small, and sometimes there is no time, so there will be the problem you said, which is a problem with the manufacturing process. You can change that knob...

The potentiometer is used for a long time, the internal carbon barrier film will be ground out by the spring sheet, and the problem can be solved temporarily by dropping it with alcohol, but it is not used for a long time, and there will be a rustling sound, and the most fundamental method is to replace the new potentiometer to completely solve the problem. If you don't believe me, you can try it and find out.

The potentiometer in the speaker has been used for a long time, or it has entered the dust, resulting in poor contact, increased contact resistance, and loud noise, so that wiping with alcohol can be temporarily solved; But if the LZ's speaker has been used for too long, it is best to replace it with a new one. If you have just bought it not long ago, it is a quality problem, and LZ can be replaced at the merchant. Hope that helps.

It has nothing to do with the computer.,It's a problem with the speaker knob.,If it's not in the way, it can be repaired.。

Just turn the sound down a little bit and you'll be good after a while. My family will be fine for a while.

The Sound & Audio Devices in the control panel opens in grey 1: There is no sound card driver.

2: There is no volume control program.

Try changing the sound card driver with the driver life.

Quote: The sound and audio devices in the control panel are gray and the dots are not open!

Is it impossible to debug? It's gray! The slider doesn't move?

Well, you're right, the sound card driver has been deleted! Because there's not even a little horn, right? But you don't know how to back up!

In this case, if you lose it, you will be restored! It's a pity you didn't back it up! Drive your life to be backed up!

A: "Control Panel" - Sound and Audio Devices" - put the volume band icon into the taskbar" used to be manually turned off. Just turn it on.

The second type: "Put the volume icon into the taskbar" is checked, which is invalid. Missing, file path C: Windows system32, you can upload one on another machine, or find a system disc to find the file and copy it to system32, then rename.

Type 3: If you have used software to delete startup items and accidentally deleted the volume icon of startup. At this time, the "Put the volume icon into the taskbar" is checked, and the volume icon appears, but the volume icon does not recover after rebooting, and it must be set in the control panel again.

In this case, the network connection icon may also disappear).

In this case, it is enough to restore the deleted entry by starting the empty item in the registry.

Start "-Run" Enter regedit, open the registry, open hkey local machine software, Microsoft Windows CurrentVersion, run and create a new string in its right window""systray""(right-click on run) and the key value (double-click on systray) is""c:\windows\system32\"", if it is a win2000 system, it is""c:\winnt\system32\""That's it

Fourth: Use anti-virus software to eliminate the problem of no small speaker in the lower right corner caused by Trojan virus, and solve your troubles safely. Hope.

Delete the driver and reinstall the driver.

First, first confirm that the hardware is fine. If the speaker is fine, the sound card is fine, and if you've tested it on other machines and it's really good, then you can read on.

2. Make sure all the cables are exactly right. Then power on the speaker and turn on the volume switch.

3. Install the driver of the sound card correctly, if it is an onboard sound card, it is best to install the driver provided on the driver disk of the motherboard.

In fact, the computer does not make a sound, and many times it is because the sound card is not driven correctly. In general, after the sound card driver is installed, there will be a small speaker icon in the taskbar in the lower right corner. ）

Fourth, if you are sure that the driver is installed correctly, then take a look at the volume settings in the computer.

The specific method is to double-click the speaker icon in the taskbar, and check whether the volume is turned off to the minimum in the "Volume Control" and "Waveform" dialog box in the pop-up "Volume Control" and "Waveform".

If these two options are not available in the dialog box, click on the "Options" menu - select "Properties" - select "Volume Control" and "Waveform" in the "Show Volume Controls" and then set them correctly.

Note: Step 4 can only be set up after the driver for the sound card has been installed correctly.

Take a look at the settings in the control panel, sound and audio devices.

Desktop? Is there a bit of a problem with the interface?。。 Oh!

Or is the sound card itself over?
