Computer sound is indeed a very depressing thing, help center and friends were made to sleep and eat. To put it mildly, anyone who encounters this kind of thing won't have peace of mind 。。。。。
Now we will introduce you to the common computer without sound processing method.
One, first of all, to confirm that the hardware is not a problem. You've already said that the speakers are fine, the sound card is fine, and if you've already tested it on other machines that are indeed intact, then you can continue on...?
Two, make sure all the connections are exactly right. Then power up the speakers and turn the volume switch on.
Three, install the driver for the sound card correctly, if it is an on-board sound card, it is better to install the driver provided on the motherboard driver disk.? If the sound driver is not installed properly, it will appear as a yellow "?" in Device Manager Or in Sound, Video and Game Controllers, Sound Audio Controller has a yellow "!" Below:
If when installing the ?HD?Audio? sound card driver it prompts, "The ?HD?Audio? bus driver is required but not found."
Installing this patch solves the problem.

(In fact, a lot of times when a computer doesn't produce sound, it's because the sound card driver is incorrect. Generally, after the sound card driver is installed, there will be a small speaker icon in the lower-right corner of the taskbar)
Four, 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: double-click on the taskbar in the trumpet icon, in the pop-up "volume control" dialog box to see the "volume control" and "waveforms" in two! The volume is either minimized or muted.
If these two options are not present in the dialog box, click on the "Options" menu - select "Properties" - and under "Show the following volume controls" - select "Properties". Below:
Check the volume control switch on your headphones and speakers. Is it minimized or muted?
Check the volume of windows' own playback software ?RealPlayer? and ?Windows?media?Player? and whether they are all adjusted to the minimum, or mute, the following figure
Now some sound cards, there are interface sensing function, for example, if you plug in the stereo or headphone, it will pop up a window to let you choose what device you plugged in. What is the device, when you choose wrong, it may lead to no sound, here must be set correctly.
Special reminder: In fact, many times, the computer does not work properly because of minor problems, soft faults, carefully analyze, many times are able to solve the problem easily.
Fifth: users unfamiliar with the BIOS may have mistakenly shielded the onboard sound card.
Enter BIOS, select I/O?Device?Configuration→Onboard?AC97?Audio?Controller, select ENANLE or AUTO. My motherboard is ASUS, the other due to the different motherboards, or BIOS version is not the same, there may be some differences, but also basically similar, if it is Award? BIOS, enter the BIOS "Intergrated? "AC97 Audio" and change "Disable" to "Auto" to save it.
Sixth, after installing a network card or other devices, the sound card is no longer sound
This problem is more representative of the majority of compatibility issues and interruptions caused by conflict. ?46jh-4)?
Driver compatibility issues are easier to resolve, as users can update the drivers for each product. The interruption conflict is more troublesome. First of all, go to the control panel → system → device manager, query the respective IRQ interrupt, and can be directly in the manual setting of IRQ, to eliminate the conflict can be. If the device manager can not eliminate the conflict, the best way is to go back to the BIOS, turn off some unneeded devices, empty the excess IRQ interrupt. It is also possible to switch the NIC or other device to a different slot, which will also change the respective IRQ interrupts in order to eliminate the conflict. After changing the slot, you should enter the "PNP/PCI" item in the BIOS to change "Reset?Configutionration?Data" to ENABLE, clear the PCI device table, and reassign the IRQ interrupts. The IRQ interrupts can be reassigned.
Here are some of the more common troubleshooting methods for the lack of sound 。。。。。。
Often in the help center will also come across some netizens put forward, I in the local playback of MP3, songs have sound, why open the site to watch the video will have no sound
You in the local playback of the sound, which proves that your sound card, headphones (speakers), the driver is all right, basically belong to the setup problems 。。。。
You first check if the web player has sound turned on. Below:
If you are using IE, open Tools---Internet Options ---- Advanced--You see the following picture, your whether all open.
If you are using the Oceanis browser, in the lower right corner of the browser, there is a sound icon on the status bar, you check to see if it is muted....
Of course, other browsers will have similar settings, because I now only use IE and Oceanis, other browsers have not been used, then you need to double-check the settings 。。。。。。。。
