Make your sound card work efficiently

In this multi-media age, the melodious sound is always the pursuit of our efforts. But to make a wonderful sound of your own computer, you must also "help" with the sound card. But not every sound card can emit high-quality sound signal, it and the quality of the sound card itself has a relationship, in the same quality depends on how we will "tune" the sound card, so that the sound card can be more efficient use of potential. Below, the author provides a few to let sound card skill, hope these skills can be useful to everybody.





1, output audio information with line out





you know, in general, the sound card and headphones are supporting the use of, when we play on the computer through the playback of an audio file, sound information can be from the sound card on the speaker Jack output, voice information through headphones will be transmitted to our users ' ears. At this point, the curious user may ask, why should the headset be plugged into the speaker Jack of the sound card instead of inserting the line out jack? This is mainly because the output of the speaker will have a certain amount of amplification, this will ensure that the output of the sound signal can be accurately transmitted through the headset to our user's ears, while the output from the line out of the audio information is less distorted, but not magnified, if the headset transmission, the user will be difficult to listen to clearly. Of course, we can also get the sound card out of line output, but this requires us to set the jumper. On the sound card, we will find a set of jumpers, when the line out mode is selected, the speaker hole in the output is line out audio, and you choose SPK out mode, speaker hole output is speaker audio. 3lian.com





2, improve the "soft" performance of the sound card





In general, we can make some necessary "soft" settings for the sound card in the Windows environment to improve the performance of the sound card. When setting, we can use the mouse to open the Control Panel window and the multimedia window in turn, select the Audio tab in the pop-up multimedia window, there is a "advanced" button in the sound playback, there are several places to choose. The first is the speaker, select an option closest to the device used, and then to the Performance tab of the Advanced audio properties. There are two sliders on the Performance tab, which are hardware acceleration and sample rate conversion quality respectively. To get the best results without considering the system performance, it is recommended that you move the two sliders to the far right. Some new CD-ROMs that offer the option of digital audio playback. This improves the playback quality of the CD track (a lot of the game background music is in CD tracks) because the analog signal is easily distorted in the transmission and the digital signal does not. On the Control Panel, open the System Properties, open the properties of the CD-ROM, on the Properties tab, the "digital CD playback" item, and if the CD-ROM is supported, check the left side of the "Enable digital CD audio for this CD-ROM device."





3, upgrade the sound card program





sound card in the course of use, encountered in this or that reason, may not work properly. If we exclude a variety of possible reasons, the sound card still does not work, we can consider reinstalling the driver of the sound card or the sound card driver to upgrade, because the sound card program is too low or the sound card program is destroyed, can cause sound card "strike"! When installing a sound card driver, select "Manufacturer supplied driver" instead of "Windows default driver" If you install with "Add New Hardware", choose "Install from disk" instead of selecting from the list box. If you have installed a driver with Windows from, optional "control Panel"/"System"/"Device Management"/"sound, video and game controllers", each of the points in the point, select "Properties"/"Driver"/"Change Driver"/"from disk installation." Insert the disk or disc that came with your sound card and load the driver supplied by the manufacturer.





4, solve the problem that can not be recorded





If we find that the computer is not recording correctly, the problem may appear on the sound card. At this point we should first check whether the jack is "microphone input", second, double-click the trumpet, select "Properties"/"Recording" on the menu to see if the settings are correct. Next, adjust the mixer devices and line input devices in Control Panel/multimedia/devices to set them to use status. If the audio recording option in multimedia/audio is grayed out, that would be bad. Of course, there is no room for salvation, you can try "Add New Hardware"/"System Device" add "ISA Plug and Play Bus", if not, the sound card driver installed again, if not, Simply put the sound card with the card tool software installed after the reboot.





5, manual settings to identify the sound card





you know, the most common and headache problem we have when installing a sound card is that Windows 95/98 does not recognize the type of this sound card, even though we already have the correct driver installed in the system. The options listed under items such as "other detected devices" or "Unknown devices" in Device Manager are usually sound cards or other devices. In order for Windows 95/98 to recognize this sound card, we can forcibly perform the following steps, which, if lucky, will make the sound card sound! The following steps are specific: first disconnect the computer power, open the chassis, unplug the sound card from the motherboard's sound card slot, then re-run the computer, boot the system with a DOS boot disk, and then the hard drive for low-level formatting, partitioning and advanced formatting, and then reinstalling Windows 95/98 after the installation is complete, Shut down, then plug the sound card into the ISA slot, and then rerun the computer again and insert the driver disk, a new Hardware dialog box appears asking you to install the driver for Windows 95/98 when it detects new hardware. When you are asked about the driver path, insert the appropriate driver disk, and then click the "Install from disk" button. In the pop-up dialog box, enter or select the drive letter of the driver (of course, you can also click the Browse button, select the driver's letter and path in the dialog box that appears, click the OK button, and then click OK to open the driver letter and install the driver. If the installation succeeds, Windows 95/98 will appear with a dialog box that requires the computer to be restarted and the sound card will function when it starts.





6, properly installed sound card





The sound card does not work properly, in addition to its own quality problems, there are also a large reason is that factors, such as the sound card is not accurately positioned in the slot, the sound card will not work. Because the chassis manufacturing accuracy is not high enough, the sound card outside the manufacture or installation of the sound card can not be closely combined with the board expansion slot, visual visible sound card "golden finger" and expansion groove Reed dislocation. This behavior is common to both ISA card and PCI card. Can be used to correct the general pliers.





7, change the wiring sequence of the audio line





when we use a computer to play CD music, we may find that there is only one sound channel in the speaker. The possible cause of this phenomenon is that the audio line contact is bad or not one by one. We know that the optical drive output generally left and right two lines of signal, the middle two lines for ground. Because the 4 line color of the audio signal line is generally different, you can find one by one corresponding interfaces from the color of the line. If there is only one interface on the sound card or each interface and the audio line does not match, you have to change the wiring sequence of the audio line, usually only 2 of the line can be swapped.
