Why is the speaker not responding? What s going on when the speaker is plugged in and doesn t reflec

1. Poor contact with sockets and signal wires.

2. The computer is set to mute the speaker in the lower right corner.

3. There is no speaker in the lower right corner of the system problem.

There is no sound on the computer, such as no sound when the computer is turned on, and the small speaker in the taskbar is missing

First of all, the computer is silent and seems simple, but in fact, sometimes the problem is more complicated, involving both the hardware aspect.

The problem, in turn, relates to the software side. There are also sound cards that do not sound due to sudden crashes and small speakers.

Disappearance is also common. Therefore, it is important to find out the cause first, see if it is a software failure or a hardware failure, and then prescribe the right medicine for the problem.

1. Check whether the sound card, cable, speaker and other devices are connected normally. If you have a virus, you should run antivirus software for full antivirus.

2. Open the control panel--- Add new hardware--- Next, after the search is completed, click "No, I haven't added this hardware", click Next. In the dialog box that appears, check Click Done, shut down the computer, restart to add new hardware. Note that this refers to shutting down and then starting, not restarting.

In general, the problem can be resolved after rebooting.

--- the volume of the device, put a check mark before "put the volume icon in the taskbar", and put it in the taskbar after restarting.

There's a little horn again.

6. When there is no sound and no speaker, open the control panel ---Add and delete programs--- Add and delete.

windows component, put in.

New hardware, just follow the prompts to install it.

7. If you can't solve the problem, you have to reinstall the system and drivers, and everything is asked.

card drivers, or internal software conflicts. This has to be done step by step for different reasons.

Settle. 9. You can gently pat the shell of the computer body, and the laptop can be on the cover.

When the force is slightly greater than usual, so that some loose parts are restored, and wait for a period of time after shutting down.

Re-open the question for you,I'm probably only so much,I'm usually resident in the love hifi forum,If you have any questions,Please go to the love hifi audio forum expert version to find me。 machine, sometimes the sound problem will get restored.

If the speaker is broken, it must be repaired, if it is troublesome, it will be replaced with a new one, and a few dozen dollars will be a set of small speakers, hehe

Looking at your description, the preliminary judgment is that the speaker is broken. Hehe.

The ear can be heard, which means that it is not a computer problem

There are only 2 situations when the computer speaker is plugged in and does not respond. 1. The sound card driver is lost or the sound card is damaged.

2. The speaker is not powered on or damaged.

Solution: > go to the device manager to check the sound card driver, if a yellow exclamation mark appears, you need to install the driver.

1) Use the random drive disc to install.

3) Use third-party software, such as driver wizards, to check hardware installations.

Check whether the speaker is connected to the power supply, whether the socket is fully inserted into the computer sound card, or you can plug in the mobile phone to test whether there is a problem with the speaker, if there is a problem, it needs to be repaired or replaced.

Computer speakers are divided into one-piece portable computer speakers, which are single cabinets; Split computer speaker, composed of multiple cabinets. Computer speakers, as the name suggests, are used to connect to computers, of course, many can also be used to connect to other ** devices such as mobile phones.

Many Bluetooth speakers, plug-in card speakers, etc., can be used as one-piece portable computer speakers after adding external input, and this kind of speaker is very popular in the market.

1,Check whether there is a hardware fault in the speaker,Power failure is a more common phenomenon,Check whether the affected power supply is normal,For example, loose,Line damage, etc.。

2, then check whether the speaker is damaged, connect to the TV to see if it can work normally.

Hope it helps, dear.

Normal power amplifier, close to the power amplifier a few seconds after powering on, you can hear the sound of horn protection relay sengsing. If you can hear the sound of the relay engagement, it means that there is no major problem with the power amplifier.

In general, there is only a horn protection circuit in the power amplifier, and there is no other protection circuit, even if the power amplifier circuit is faulty, it will not automatically shut down. After 3 seconds of power-on, it will be [turned off], you should check whether the power switch and the fuse are in good contact, the focus is to check whether the fuse and the fuse socket are in good contact.

Check in three steps:

1. Check whether the 220V power supply is in place and whether the switch can be turned on or off. Whether the fuse is in good condition.

Second, the horn can not be opened, and the protection circuit should be properly engaged.

3. If the power supply is normal, the horn is in good condition. The preamp signal is also normal. The power amplifier is faulty, the power amplifier system is more complicated, and the technology is immature and the experience is insufficient, so it is best to find someone to repair it to avoid greater losses.

If there is sound when the speaker is powered on, the speaker cable must not be broken,Please quickly adjust the volume knob after powering on,Listen to whether the noise changes in size with the adjustment,If it can be changed,It means that the power amplifier circuit is good,It is the preamplifier part of the channel where the speaker is located (that is, the amplification circuit of the audio input to the volume adjustment part) is damaged,On the contrary, the power amplifier stage (power amplifier integrated circuit) that channel is damaged。

If you do not have a foundation in electronic circuits, it is recommended to send it for repair, and you need to use tools to inspect it. The most easily damaged part is the power amplifier manifold, usually use TDA2030, if you can be sure that the power amplifier level is broken, if you have an electric soldering iron, you can disassemble to see the model of the power amplifier manifold, to buy a replacement, the power amplifier manifold is 5 feet, and it is not too difficult to replace. If the pre-circuit is damaged, it is more troublesome and can only be sent for repair.
