Listen to the sound with a headset and be able to hear it clearly, and the voice is very small, and

Quite simply, you plugged in the wrong hole.

You plug the headphones into the middle hole, the microphone into the first hole, absolutely.

Try a new headset. If the result is the same. Then update 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 due to the incorrect driver of the sound card. Under normal circumstances, after the sound card driver is installed, there will be an icon of a small speaker 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 the following volume controls", and then set the mask correctly.

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

Are you a blind model, not with an integrated sound card with a high-end headset? If so, it's normal to be quiet. The first is that the response frequency band of the high-end headset is large, the higher the sound card, the more weakened the low-frequency part, the second integrated sound card The distortion requirements are not very strict, mainly with the grinding of the old and slow multi-** speaker, the high-end headset requires a high degree of distortion, and the output power of the integrated sound card with the high-end headset is very reduced.

Generally, the effect of an integrated sound card with a headset similar to that of Sakura is better.

Did you select the microphone in the Recording Control panel in the Volume Properties? And is it up to the maximum? It doesn't matter if the microphone is plugged in front or behind, as long as the jack on your case panel is good.

Do not use sharp objects (such as hairpins. Velvet needles, etc.). so as not to bruise the eardrum.

It's best to quit the habit of picking your ears.

It is necessary to have a certain understanding of the dangers of purulent otitis media. Watch for early symptoms of serious complications. Such as ear disease accompanied by headache.

Fever. Disgusting. Vomiting, etc.

When otogenic intracranial comorbidities are suspected. It should be treated early. so as not to delay the condition.

Go to the hospital to see if it is possible for earditis But it should not be a big problem, so it is more reassuring to take some anti-inflammatory drugs.
