Questions about computer audio output 120

There is sound in the front, which means that the sound card and driver are good, and there are two possibilities for no sound in the back, 1The interface behind is loose, 2 You plugged in the wrong port.

It's normal for this pre-audio sound effect to be bad, because most of the pre-output of the case is still analog, and then you can change the pre-audio in the BIOS to AC97 to try, generally plugged in the front, there will be sound in the back, you can turn off the speaker, and then use the front, and you can update the sound card driver, or change to a good headphone, you can improve it slightly.

I don't know what kind of sound card you are, generally speaking, the old AC97 does not need to be specially set up on the front panel to be used normally, while the HD AC97 sound card must be set up before the front panel can be used.

Audio output, the sound signal is output through the audio interface, the commonly used analog audio output interfaces are TRS, RCA, XLR, etc., and the digital audio output interfaces are S PDIF, HDMI, etc. Audio input refers to the process by which the sound of the monitored area is captured and sent to the monitoring center.

The audio input port can input the sound source of other devices into the mini combination speaker, usually the mini combination speaker with the recording function has this interface, in addition, the audio input interface can also be used to pass the sound of other audio sources through the mini combination speaker**, the common audio input interface is the RCA port.
