Solution for unrecognizable and installed sound card

Fault analysis: Since the sound card supports plug and play, open the “Device Manager” as usual, check the resource conflict, but there is no “sound, video and game controller” item. Suspected to be caused by poor contact, so shut down and re-plug the sound card, no new hardware was found. With the minimum system method (only graphics card and sound card) or not. Directly install the sound card driver, the volume control icon still does not appear in the system tray, although the "sound, video and game controller" appears in the "Device Manager", but each has a yellow exclamation mark, all deleted.

Open the "Control Panel" and select "Add New Hardware". As a result, Windows prompts that no new hardware can be found. Enter the BIOS setup program to check, the onboard sound card is set to Disable, the resource allocation in "PnP/PCI Configurations" is also set to Auto, the "Onboard Legacy Audio" in "Integrated Peripherals" is changed to Enable, and the system is still invalid after restarting the machine. . No virus was detected by using various anti-virus software. Suspected registry errors, deleted Windows, formatted the hard drive reinstallation system, and installed the latest version of the VIA 4-in-1 driver, still can't find the sound card.

Troubleshooting: Re-enter the BIOS, press F6 (ie select "Load Fail-Safe Defaults" item) and press Enter, then type "Y" to confirm, after starting Windows, prompt "Found new hardware, Look for the driver", quickly insert the sound card driver CD and install the driver. With crisp, sweet music, everything is OK! After trial and error, if "PNP OS Installed" is set to Yes in the BIOS, Windows will ignore the sound card and must be set to No.

Summary: When there is a problem with the installation hardware, first check whether there is a resource conflict in the system "Device Manager", you can delete the option with the question mark and the yellow exclamation point, try to adjust the resources manually, then Be sure to install the motherboard driver. If not, check the settings in the BIOS. In addition, you can use the minimum system method, anti-virus or even completely remove and reinstall the system. Another area that is easily overlooked is the conservative settings provided by the BIOS setup program, which often yield unexpected results.
