I bought a USB sound card online. It just arrived today. After connecting it for more than ten minutes, I suddenly found that there was still sound after unplugging the USB sound card! ! ! It's good again! ! ! I just bought a sound card. . . . . . .
So just wait patiently, who knows when it will be better. . . .

If you have certain hands-on skills, you can try to disassemble the phone, unplug and plug in all the audio cables again, and plug them in tightly. Maybe it will get better. My laptop had no sound again a few days ago. Most likely, some of the wires were not plugged in properly when I replaced the silicone grease.
The suggestion is for reference only. If you are not sure about disassembly, please don’t do it. We will not be responsible for any damage.
The following is the original answer
Waiting.
No kidding, that’s what I do. This was the problem with laptops last year. It was being used normally, but suddenly the speaker made a loud noise, and then there was no sound for no reason, and there was no sound when the headphones were plugged in. But the volume can be adjusted and the speaker itself is fine. The strangest thing is that the sound comes and goes, depending on the mood of the notebook. It's there when you're in a good mood, but not when you're in a bad mood.
Then I went to the after-sales department for inspection. The after-sales department asked me to reinstall the driver and system, but it still didn’t solve the problem. After-sales service said there might be a problem with the sound card. They replaced the sound card, but the problem persisted.
There is really no choice but to take it back and use it silently. It turned out that after about two months, it suddenly got better? ? ? ? It's been over two years now and there are no more problems. . . . . .
It’s really metaphysics.
It seems simple to have a silent computer, but sometimes the problem is more complicated, involving both hardware and software issues. Therefore, we must first find out the cause, whether it is software or hardware failure, and then prescribe the right medicine for the problem. The troubleshooting method for computer silence is as follows:
1. First check whether there is a "small speaker" on the right side of the taskbar. If so, the sound card is normal. The cause of the fault may be that the system sound is too low, or mute is set, or the speaker is faulty. You can continue to check whether there is sound output through the headphones. If there is, the speaker is faulty.
2. If there is no "Small Speaker" on the right side of the taskbar, then click the "Control Panel/Sounds and Audio Devices" command to open the "Sounds and Audio Device Properties" dialog box, and click "Sound" in this dialog box " tab, then click one of the program events (such as a program error) in the "Program Events" column, then select a sound type, and then see if the "Preview" button on the right is black. If it is black, the sound card is normal. The cause of the fault may be that the system volume is too low, or mute is set, or the speaker is faulty.
3. If the "Preview" button in the "Sound" tab is gray, then click the "Control Panel/System Properties/Hardware/Device Manager" command to see if there is a yellow "?" in the "Device Manager" window? " option.
4. If there is a yellow "?", check whether the option is a sound card device option (the sound card device option usually has keywords such as "Audio" or "Sound"). If it is an option for the sound card device, it means that the sound card driver is not installed. Reinstall the sound card driver and the silent problem will be solved.
5. If the yellow "?" option does not refer to the sound card device, or there is no yellow "?" option, then check whether there is a yellow "!" option under the sound, video and game controller tabs.
6. If there is a yellow "!", it may be caused by a mismatched sound card driver or an aging sound card. Then delete the option with "!" and reinstall the sound card driver.
7. If there is no sound card option in the "Device Manager" window and the sound card is an integrated sound card, then restart the computer and enter the BIOS program. Then check whether the peripheral device option in the BIOS is set to "Disabled", if so, change it to "Enable". If this item is set to "Enable", the motherboard sound card circuit may be damaged, and the sound card circuit can be repaired.
8. If the sound card is not an integrated sound card, then open the case and check whether the sound card is installed properly. If it is not installed, just reinstall it and start the test; if the sound card has been installed, then remove the sound card, and then clean the motherboard sound card slot and the dust on the sound card (especially check whether the gold finger has mold spots, etc.). After cleaning and reinstalling, general faults can be eliminated.
9. If the sound card is still not normal, there is a problem with the sound card. Use the replacement method to check whether the sound card is damaged or incompatible with the motherboard. If the sound card is damaged or incompatible with the motherboard, just replace the sound card.
10. Download the sound card driver. It is recommended to use Driver Wizard to download drivers compatible with the sound card.
I am running a win10 system. Occasionally, NetEase Cloud suddenly has no sound.
First open NetEase Cloud and play a song at random, then open the control panel - Hardware and Sound - Sound - Adjust the system volume - Unlock NetEase Cloud from the muted state.There are following possibilities: Either the channel balance in the system has been adjusted to the left, just adjust it back.
Either the motherboard jumper is not connected properly, or it has oxidized over time,
resulting in a virtual connection. Open the case and check it and it will be OK
Either there is a problem with the shrapnel of the output interface. The upstream line is good,
but the shrapnel of the right channel does not contact the audio connector at the interface
Then there is a problem with the audio cable or speaker, remove the speaker Try connecting to another output device.
If there is no sound from the computer, first determine whether the sound is muted, and then determine whether the sound card is broken. If the sound is muted, turn off the mute. If the sound card is broken, you need to replace the sound card.
Method:
1. In the control panel, there is a setting to put the sound icon into the taskbar. If the setting is modified, the sound icon and the small speaker will not be displayed on the taskbar. The setting method is as follows. First, enter the control panel through Start-Settings-Control Panel or the left side of My Computer, and double-click to open the sound and audio devices.
2. After opening the sound and audio device, check the box "Put the volume icon into the taskbar" under the volume, and then apply OK. This is the first step. If the sound icon speaker does not appear yet, You can proceed to the second step.
3. If it still doesn’t come out, another reason is that the sound icon speaker is hidden, and the recovery method is very simple. Right-click to view the properties of the taskbar at the bottom of your computer.
4. In the taskbar properties window, click the custom button behind Hide custom icons.
5. Then in the custom notification window, select the volume display behavior to always show. After final confirmation, the computer sound icon and small speaker will appear.
Other software has sound and Bluetooth is fine, then there is a problem with Guangyu. It is normal to have a stuck bug. Exit and re-enter. If the phone is hot, wait for it to dissipate Let the heat dissipate and try again.
It may be a problem with the program settings. Check the sound configurator in the speaker icon in the lower right corner to see if it is muted or adjusted to mute. Check to see if the app's own volume button is pushed all the way down.
You can also use 360 to check whether there is a fault. I remember there was a special repair for silence.
What to do if the computer host is flooded with water
The computer host is one of the most important components in our daily use of computers, but sometimes we inevitably encounter some unexpected situations. For example, the computer host accidentally gets water. In this situation, everyone may feel confused and not know how to deal with it. Today we will discuss how to deal with water in the computer host.
When you find that water has entered the computer host, the first thing to do is to turn off the power immediately. This is a very important step because electric water can not only short circuit the circuit but also cause damage to other components. Therefore, do not attempt to continue using the computer, but quickly disconnect it from the power supply.
After the power is cut off, the next step is to disassemble the computer host and clean it. First, you need to open the host casing, and then remove the internal components, such as the motherboard, graphics card, hard drive, etc. Next, each component can be cleaned with a hair dryer or a clean cloth to remove any remaining moisture.
洗浄後は各部品を乾燥させる必要があります。換気の良い場所に置くか、ヘアドライヤーを使用して残った水分を乾燥させます。電子部品の損傷を避けるため、高温の送風機を使用しないように注意してください。
洗浄して乾燥させた後、各部品が完全に乾燥していることを確認するためにしばらく待つ必要があります。このプロセスには 1 ～ 2 日かかる場合があるため、辛抱強く待つことが重要です。待っている間、急いでコンピューター ホストを組み立てないでください。
すべてのコンポーネントが完全に乾いていることを確認したら、コンピューター ホストの組み立てを開始できます。各コンポーネントが正しく取り付けられ、配線されていることを確認し、電源を再接続してテストします。すべてが正常であれば、コンピュータ ホストは正常に起動して動作するはずです。
上記の手順を実行すると、ほとんどのコンピューター ホストは通常の動作に戻ることができますが、コンピューターの起動を妨げる短絡やコンポーネントの損傷など、依然として問題が発生する場合があります。この場合、時間内に専門のメンテナンス担当者にメンテナンスを依頼することをお勧めします。
コンピュータホストにとって水の入手は非常に面倒ですが、正しい方法を採用している限り、ほとんどの場合コンピュータホストは修復できます。このような状況に遭遇した場合は、安全性と信頼性を確保するために、まず冷静に対応し、すぐに電源を切り、テスト前に正しい手順に従って洗浄と乾燥を行う必要があることを覚えておいてください。
