What should I do if my computer stereo has no bass

Buy a standalone sound card Sound cards are cheap right now. Otherwise, try the Control Panel.

Sound settings. There's a sound acceleration in there. Turn it down a little and try to right-click on the desktop "My Computer" Properties Hardware Settings Manager Sound** and Game Controllers There is no AC97 or High Definition or other long strings of English below this item, or there is a yellow question mark.

Click on the bottom left corner of the desktop to start the Control Panel Sound & Audio Devices All settings are grayed out, i.e. they are not available. If either of the above two situations exists, then you directly **" drive the wizard.

If the above two situations do not exist, please follow the steps below. Step 1: If there is no small speaker in the bottom right corner of the desktop.

Start the Control Panel Sound & Audio Devices tick on the "Put the volume icon into the taskbar."

Are you sure.

The speaker is generally not broken, then it is a bass adjustment problem, or the signal transmission problem caused by the aging of the connection cable, rule it out.

1. The speaker wiring is broken or the crossover is abnormal.

When the speaker wiring is broken, the speaker unit does not have an excitation voltage, which will cause a silent failure. Frequency dividers are generally not easy to break, but failures such as desoldering of lead joints and short circuits of crossover capacitors may occur.

2. The voice coil is broken.

Solution: You can use the multimeter R 1 gear to measure the solder lug of the speaker lead-out wire, if the resistance value is , you can use a knife to scrape the paint of the lead wire at both ends of the voice coil, expose the bare copper wire and then test, if it is still not through, it means that the voice coil is broken internally;

If the measurement has been passed and there is"Titicaca"sound, it means that the voice coil lead is broken, you can solder the thread well, and then use a piece of enameled wire similar to the voice coil winding to solder it.

3. The speaker lead is broken.

Due to the frequent vibration of the speaker cone, the braided wire is prone to breakage, and sometimes the wire is broken, but the cotton core wire remains connected. This type of braided wire is not readily available and can be replaced with a slightly longer flexible wire.

There are several possibilities and solutions for the speaker without bass:1、See if there is a knob to adjust the bass behind the speaker,Whether the bass knob of the speaker is rotated to the appropriate position。 Generally, the bass knob "bass" is rotated to a medium position and should not be too large.

2. There are no subwoofers at all, such as speakers and bookshelf boxes, this kind of speaker is generally two, there is no heavy bass, and there will be no strong bass. If the speaker will have a heavy bass, and adjustable, this speaker has two satellite cabinets and a subwoofer. 3. The bass quality of the audio source is not good.

Generally speaking, some DJ** has good bass quality, some have compressed audio quality and decreased, or if they are not done well, the bass will be dull and boring. It can be done in high fidelity (hifi). 4. Is there a problem with the audio cable?

Generally, the socket that is removed from the computer is the socket, so the plug should be in good contact with this socket and be reliable. Problems with the quality of the cables, such as virtual solder points, can affect the sound quality. You can try to change the cable.

5. Sound card, **Software problem. Whether the sound card driver is normal, if the sound card software has an equalizer and sound mode, you should select default or none. If you adjust the equalization of the ** software and pull down the bass segment, the bass will not be noticeable.

There is no bass. Explain that the audio source has been fed,First of all, you should use a computer-type multi**speaker。 It is certain that the fault appears inside the attack amplifier, most of the multi-** speakers are damaged quickly for the power amplifier, and there is also a bass volume adjustment potentiometer.

If this original is damaged, there will be no sound, so it is recommended to replace the bass amplifier quickly should solve the problem of the stall.

Sound refers to other sounds other than human language, including the sound of the natural environment, the sound of animals, the sound of machine tools, and various sounds made by human movements.

The audio probably includes a set of power amplifiers, selling stupid ruler peripherals, speakers (speakers, speakers), mixers, microphones, display equipment, etc. Among them, speakers are sound output devices, speakers, subwoofers, and so on. A speaker includes three kinds of speakers: high, low, and medium, but not necessarily three.

It's a very simple thing,Originally, this kind of audio input signal is the plug,2Small speaker is normal,It means that the input signal source is normal,The subwoofer sound is small,In addition to the subwoofer, the potentiometer that controls the sound,Or the electronic control place is broken,If it is not,It is a pure subwoofer alone that power amplifier part of the problem,There is sound,Most of the peripheral parts are broken,**Most of them are the capacitance leakage problem of the patch,Very few are the power amplifier part or the chip is broken。

First update the sound card driver,If you can't solve the problem, try another audio cable,If the above methods don't work, it may be that there is a problem with the subwoofer itself。

If it doesn't work, I can't help it, ask someone else.

First, it may be a subwoofer failure, measure the speaker impedance; The second is the failure of the bass amplifier circuit, which is generally the damage of the power amplifier module.

Switch the speaker to another computer, and if you have one, just switch it back again. You're welcome!

The solution to the failure of the host built-in speaker is as follows:

1. When the built-in speaker of the host is faulty (abnormal noise or no sound), it is recommended that you connect the headphones to test and confirm whether the headphone output is normal. If the sound of the earphone output is normal and the built-in speaker of the host is abnormal, there may be a problem with the built-in speaker of the host, and it is recommended that you report the machine for repair.

Note: Split desktop PCs generally do not have built-in speakers.

2. If you connect the headphones for testing, the sound of the earphone output is also abnormal, it is recommended that you reinstall the sound card driver.

3. After installing the sound card driver, if the problem is solved, it is possible that the fault is caused by a problem with the sound card driver.

4. After installing the sound card driver, if the problem is not solved, please consider restoring or reinstalling the system after backing up the data, or report the machine for repair and let the service station engineer help you detect and repair.
