There was no sound on the computer, and the little speaker in the lower right corner of the screen w

Let me tell you about the situation of the small trumpet!

You open the control panel! Find the sound that option and see if your computer is muted or not!

I think the brothers upstairs are talking about it!

The first thing to check is this question!

Yes, it's not a universal sound card, it's all sound cards together. Let you choose. It also depends on what your chip looks like.

Check if there is any problem with the sound card driver!

Right-click"My computer"Select Properties and go"Hardware-device management"Look inside to see if there is a yellow question mark in front of the sound card If there is a problem with the driver of the reputation card Take a look at the model and then go to the Internet to search for the driver and install it OK.

The drive inside is relatively complete!

You're not right! To go to the Control Panel - Sound & Audio Devices, then there's an option to "put the volume icon into the taskbar", just tick it, and you're going to see if it's muted

The sound card driver is not installed, as long as you install it, a small speaker will appear.

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.

Start – Set up --- control panel --- sound and audio devices. There should be one.

Place the volume icon in the taskbar.

If this item is already ticked.

Please right-click - My Computer.

Attribute. - Hardware – Device Manager.

Look. The sound card driver is not installed.

Generally, there is a yellow question mark on the unloaded.

I've also encountered it in the past two days.,I've seen a lot of answers to these kinds of questions.,But I didn't find out.,I've finally done it well.,Share it with you.,1Click "Start"-"Settings"-"Control Panel"-"Sound, Audio Devices"Device "Device Volume"Put the volume icon into the taskbar"Tick "Advanced"-"Options"-"Properties"-Show the following volume controls-Pull down, check in front of "Microphone Volume", and then click on the OK.

2After entering the control panel, find "Sound and Audio Devices" and click to enter, find "Put the sound icon into the taskbar" in the "Volume" tab, select it and then click OK, if it is originally selected, you can first remove the check number, click OK, and then enter again, select it, and click OK.

If you follow the instructions below, your taskbar's volume icon will surely reappear.

Three situations where the volume icon disappears and the sound is still normal:

Depending on what you said, your question generally falls into the third category.

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

The second way: "Put the volume icon into the taskbar" is checked, and it 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 entries in the startup entries in the registry. But it's all in English, so you'll have to look for it slowly.

Start "-Run" Enter regeditAfter opening the registry, open the hkey local machine software Microsoft Windows CurrentVersion Run (right-click on the run to create a new string value) create a new input string systray in its right window, (and double-click on the systray to appear) copy C: Windows System32, or C: Winnt system32 is good to go.

Restart the computer and try again.

There is also the simplest solution, which you can also try, and the results are generally immediate.

The next driver wizard... It will be installed in no time.
