Usually they are specified on the card itself.
2
Go to the official website of the manufacturer of the sound card. For this in any search engine enter the name of the manufacturer or model of your device. Download the drivers from the downloads section of the website.
3
Run the downloaded file and follow the instructions of the installer appearing on the screen. After completion, restart the computer. Connect the speakers.

You can adjust the volume level, to adjust the balance between the left right speakers. If you are setting up a serious sound system, specify the connected amplifiers and the number of columns, add the desired effects and, if necessary, use the equalization of the sound.
5
If the sound is not working, check whether the power sound system is correctly connected. Try to connect other speakers or headphones, the problem may be in your audio system. Check to see if the sounds in the OS itself. To do this, click on the dynamics icon in the system tray.

Advice 2: How to set a car amplifier

Installed and connected speaker system must be configured correctly. The essence of the settings is to install the amplifier cutoff frequencies for the speakers and subwoofer, the sensitivity of entry and exit, as well as in the setting of the sound processor (if any).
How to set a car amplifier
Instruction
1
Before configuring auto & all settings on the head unit set to zero. If the design of the amplifier provides a total gain of the components that install on the amplifier filter of the subwoofer channel in low pass position. The value of the cutoff frequency of the crossover set in the range of 50-70 Hz. Filter front channel on the amp set to high pass. The cutoff frequency of the crossover set in the range of 70-90 Hz.
2
If the design of the amplifier provides the gain of each channel of front speakers, spend a separate setup speakers. For this purpose, the high pass filter set at the appropriate position (for high frequencies) and set the cutoff frequency of the crossover in the area of 2500 Hz.
3
Adjust the amplifier sensitivity. For this reset to zero the sensitivity of the amplifier to the head unit power mode maximum playback volume. Then start to increase the sensitivity of the amplifier. At the time of occurrence of distortion of the sound, stop turning the knob and slightly lower sensitivity.
4
Check the sound quality. If you turn the audio system the subwoofer audible clicks and crackle in the speakers – so there is interference with the signal. Check the gasket all the wires of the music system and, if necessary, will route them elsewhere.
5
The bass should not be tied to the subwoofer. In other words should not have the feeling that they emanate from the rear of the cabin. To remove this effect, connect the subwoofer out of phase to the amplifier. To do this, turn the phase switch on the subwoofer by 180 degrees. If such a regulator is not, switch the positive and negative wire connections from the subwoofer.
6
Adjust the sound processor, if it is built into the head unit or separated. To do this, adjust the time delays for each channel of the amplifier. Set delay time left channel to the sound from the left speaker arrives at the driver simultaneously with the sound from the right speaker. When properly configured, has created a sense that the sound is coming from the Central part of the cabin.
7
Additionally, the sound processor can de-link the bass to the rear (see item 5). For this purpose, in contrast to the recommendations in paragraph 6, set the same delay left and right channels of the front speakers. Localization of bass in the center of the subwoofer to be eliminated.
