No sound on the earphone jack in front of the chassis

Help a friend install a computer and there is no sound in the front audio interface. This is related to our application status. Simply put, this is because the front audio panel and socket wiring of ac97 cannot adapt to the automatic detection of HD. Alc888 is a high-definition sound card, and the front of the chassis we use is still the ac97 standard connector. In the past, when we connected the front audio, there was sound. It is because there were few HD sound effects, only ac'97. Currently, basically all HD sound effects are available, and HD sound effects are selected by default, while HD sound effects do not support front-end audio output, so there is no sound. So if you want to use the front-end audio, you can only change the HD sound effect to the ac'97 sound effect in Bois. There is a compatibility problem between the two, the motherboard user manual prompts: to use the ac97 front module, you must disable the front panel detection.

Method for front-end audio without sound: Disable the front-panel Jack detection function.
Method:
Go to the RealTek HD audio manager, select "audio I/O", and click "wrench icon" on the right of the Management Panel ", in the displayed page, select "Disable front panel Jack detection" and click "OK.

For the vast majority of commercially available PCs, the sound cards produced by RealTek HD Audio Ruiqi (Sound: y strong) Support HD playback occupy a large market share, but friends often find that, it is a headache to set the front microphone of a host with such a sound card. In fact, this is caused by the default settings of the sound card driver. This situation does not exist in the early a'97 sound card (Referer has already integrated most of the ac'97 sound cards ).

Black dolphin tip: RealTek's HD sound card includes the following models
Alc260, alc262, alc268, alc272, alc273, alc662, alc663, alc665;
Alc861, alc880, alc882, alc883, alc885, alc887, alc888, alc889.

In short, we need to adjust:
1. Disable the automatic detection function of the RealTek HD Audio Card Driver for the front audio panel;
2. Set the default recording device to front pink in (front pink Jack or front mic ).

If you cannot understand the preceding settings, see the following details.

Step 1: Check the settings in the BIOS of the motherboard. Keywords: Front Panel type.
Some motherboard manufacturers use auto as the default front audio type in the BIOS. You do not need to adjust the BIOS for this type of motherboard. The default value is enough.
However, in the BIOS of the Asus motherboard, the default value is HD audio, and the other value is ac'97. This option can be found in onboard devices in BIOS settings. Or appear in advanced-chipset-Southbridge.
Set this value in BIOS to the connector type of the front-panel audio connection line corresponding to the trunk box. Generally, there is only one connector named "ac'97". If there are two connectors, connect them to the motherboard according to the BIOS value. Of course, HD Audio is indicated on the other connector.

Step 2: Install the audio card driver. Although the motherboard has its own drive, I still recommend you download the latest official driver.
The driver on the motherboard is also working correctly, but the new version of the driver will bring more detailed adjustable options. Rui's HD Audio Card Driver is updated quickly. Here is the driver download page officially released for version 2.15: XP and Vista (win7 and 64-bit platforms)

Step 3: Disable the automatic detection function of the RealTek HD Audio Card Driver for the front audio panel. :

Note the clamp button in the Red Circle in the figure. If this button is not displayed, you can skip this step temporarily. Once you have finished the subsequent work but still cannot use the front microphone, please upgrade your sound card driver. Your default driver on the motherboard may not work well.
Click the clamp button to bring up "connector Settings". Here there are 1 to 3 options. The main task is to check before "Disable front panel Jack detection. You can select other options as per your hobbies. Switch to the "Microphone" on the right of "audio I/O". You can set some effects of the microphone recording (we recommend that you select all). A prompt will be displayed when you click echo elimination. OK.

Step 4: Turn on the volume control, right-click the small gray horn in the lower right corner of the desktop, note that it is not orange, the first step is to set the orange icon.

In the main volume window, select "properties" from the menu "options"

In the Properties window, you can select one of the following options:
RealTek HD Audio Output playback; RealTek HD Audio input recording. You do not need to set the remaining recording.
After HD audio output is selected, it is automatically set to "play" in the volume adjustment item (this can be selected in the old ac'97 sound card setting ). In this case, select "front" and "front pink in" in the "display the following volume control" list in the third part of the window ".
(Front pink in has multiple names, including "microphone volume" and "front mic "). Check and click OK.

Now, when you see the screen title "main volume", please pull the front and pink in slider to the top. Whether to select "mute" at the bottom of front pink in does not affect the sound recording function. The mute here is only for real-time microphone playback. If you do not select this option, the speaker will instantly play back the sound you sent when you speak to the microphone. We recommend that you set it to mute. Note that the mute button at the bottom of the front cannot be selected in this window.

Then select RealTek HD Audio input in the mixer. In the same window, it will automatically switch to "Recording ",
In the third part, we recommend that you select all.

The title of the window is "Recording Control". Note that the text at the bottom of all the slider may be "mute" or "select ".
This is different settings for different models of sound cards.
When it is set to mute, the microphone volume cannot be set to mute. You can select mute for line volume and CD volume to reduce noise interference. In this type of window, there will be a "Recording Control ", adjust the slider to the highest level and cannot be muted.
When selecting a microphone, you can only select one microphone. If one model has one front mic, select this front mic.

At this point, the pre-audio panel settings of the RealTek HD sound card are returned. All operations take effect immediately during the setup process.
Now, you can choose Start Menu> program> accessories> Entertainment> recorder to check whether the front microphone works properly.

The above setup steps seem complicated. In fact, it takes less than 2 minutes to complete all the operations.
It will not take longer for me to write this article? :)

For realtekhd sound cards, generally, after updating or re-installing the driver of the Sound Card, follow these steps to modify the default preset recording interface settings. However, due to the complex environment of PC applications, it is hard to say that during user use, the built-in voice adjustment of some software will interfere with audio settings in the operating system, such as Sina UC, qq voice chat and other software, according to the customer groups I know do have such a situation.

All in all, the default recording device in the drivers of the Referer HD Audio Card is line input, and the user end is mostly the front microphone device. Therefore, the front-end audio hardware interface of the user host is not necessarily bad. If you still cannot use the front-end audio interface through the above settings, we recommend that you check whether the front-end cables in the front box are correctly connected after-sales or repair of your computer.
