No sound issues with the computer:
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 because the sound card is not driven correctly. In general, after the sound card driver is installed, there will be a small speaker icon 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 Volume Controls" and then set them correctly.
Note: Step 4 can only be set up after the driver for the sound card has been installed correctly.
It may be caused by the following reasons: a. The card is not properly inserted, the sound card is not closely integrated with the expansion slot of the motherboard, and it can be seen that the "gold finger" on the sound card and the reed of the expansion slot are misaligned. This phenomenon is common on ISA cards or PCI cards, and it is a common fault, and finding a way to get the sound card plugged in can solve the problem. >>>More
