[Technical posts] share the ultimate solution for soundless Windows 7-general Linux technology-Linux technology and application information. For more information, see the following. Today, the Shanghai IT outsourcing service network www.itshanghai.net will share with you the ultimate solution for window7 soundless. This is the case in my Windows 7 operating system. Since I downloaded and installed Realtek high definition audio, I found that the headset had no sound. After a long time, I went to the official website to drive the driver. I used the control panel to open an icon in the upper-right corner (without any instructions) and clicked "Disable front panel detection". The sound finally came out.
As a sound card manufacturer, headphones are disabled by default in win7! What's even more strange is that the front panel detection is forbidden for sound, and this option is placed in such a hidden place. You have solved this problem, but I am OK! I am more brilliant. You have seen it.
The latest 2.45 driver of win7 system (the same is true for built-in drivers) ALC883 sound card. When you hover your mouse over the audio interface of the sound card control panel, a sound will be displayed:
They are brown-red (center, heavy bass), Black (left back, right back)
Blue (audio input), Green (Front), and the time to witness is green without sound!
Disable front-panel detection. Set it to 2-channel, headset, 4-channel, 5.1, and 7.1 green.
In device advanced settings, the device is removed from "mute the device after the front panel headset is inserted" and each audio channel is independent or the same output device.
The green hole has no sound at all. It has a slightly flexible design, that is, the blue blank can define the audio output at will. Currently, you can use the method to customize the blue blank to the front! 5.1 is available!
However, the audio source input is gone, and 7.1 cannot be set. The green jack is useless! Can a brother solve this problem? Is there a problem with me? Or can I modify it to enable more jacks to customize audio devices? Good luck.
