win7ComputerThe external sound card cannot be recognizedWorkaroundAs follows:1. Update the driver, uninstall the old driver, download the latest version from the official website and install it as an administrator; 2. Replace the USB port, preferably using the rear port of the motherboard or a USB hub with independent power supply; 3. Check for unknown devices in Device Manager and update drivers; 4. Enter the BIOS and make sure “USB Legacy Support” is enabled; 5. Test the sound card hardware and connect it to another computer to confirm that it is normal; 6. Run the driver in compatibility mode, selectwindows XP or Vista mode; 7. Make sure the Windows Audio service is running and restart the service if necessary. 8. To determine whether the USB power supply is insufficient, you can confirm it by observing the indicator light, using the independent power supply hub, or checking the power supply data. 9. If the above does not work, you can try to reinstall the system, but you need to back up the data in advance and recheck the driver and power supply settings after reinstalling.
Win7 computer can’t recognize external sound card? In simple terms, the problem may be due to insufficient power supply from the driver, USB port, or the sound card itself. Don’t panic, step by step, you can always get it done.
solution
-
Drive first: This is the most common culprit. Uninstall all drivers related to the sound card (including those that failed before), and then restart your computer. Then go to the official website of the sound card to download the latest Win7 driver, pay attention to distinguish between 32-bit and 64-bit versions. When installed, run as an administrator.
-
USB port inspection: Try changing the USB port. In particular, try to plug it into the USB ports on the back of the motherboard, which are usually more stable for power supply. If that doesn’t work, consider using a USB hub with independent power supply to provide sufficient power to the sound card. Some sound cards have high power supply requirements.
-
Device Manager Explore: Open Device Manager (right-click “Computer” – > “Manage” – > “Device Manager”) and see if there are any “Unknown Devices” or devices with a yellow exclamation mark. If so, right-click, select “Update Driver Software”, and select “Search automatically for updated driver software”.
-
BIOS setup tips: In the BIOS settings of some motherboards, USB-related options may affect the recognition of the external sound card. Restart your computer into the BIOS (usually the Del key or F2 key), find the USB configuration, and make sure “USB Legacy Support” is in the Enabled state.
-
Sound card self-check: If none of the above methods work, you can try to test this external sound card on another computer to rule out the possibility of hardware failure of the sound card itself.
-
Compatibility mode works wonders: Sometimes, even officially provided drivers can have compatibility issues on Win7. Right-clickDrive installationprogram, select “Properties”, in the “Compatibility” tab, check “Run this program in compatibility mode”, select Windows XP (Service Pack 3) or Windows Vista, and try to install it again.
-
Audio Service Status: Make sure the Windows Audio service is running. Press Win+R, type “services.msc”, find the “Windows Audio” service, right-click on it, and select “Start”. If it’s already started, try restarting the service.
Does the external sound card work properly on other systems?
This is a very critical troubleshooting step. If the sound card works normally on another computer (for example, another Win7 computer, or a Win10 computer), then the possibility of hardware failure of the sound card can be basically ruled out. This indicates that the problem is likely to focus on the system configuration, drivers, or USB ports of the current Win7 computer. Focus on driver conflicts, USB power supply issues, and system service settings. If the sound card cannot be recognized on other computers, then the possibility of hardware damage to the sound card is relatively high, and you need to consider replacing the sound card.
How to tell if the problem is caused by insufficient USB power supply?
Insufficient USB power supply is a common but easily overlooked cause. First, observe the indicator lights on the sound card to see if the brightness is not stable enough, or if the sound card “won’t start” when connected to the computer. Second, try connecting the sound card using a USB hub with independent power supply. If the sound card can work normally after using the USB Hub, then it is basically determined that it is caused by insufficient USB power supply. In addition, you can check the power supply of the USB port through the device manager. In the Device Manager, expand “Universal Serial Bus Controller”, find your USB port, right-click on “Properties”, and in the “Details” tab, select “Power Data” to view the power supply capacity of this port.
Can reinstalling the system solve the problem that Win7 cannot recognize the external sound card?
Reinstalling the system is usually a last resort, but sometimes it does solve some inexplicable problems. If all of the above methods have not worked, then reinstalling the system can be an option. Reinstalling the system can clear possible driver conflicts, system misconfigurations and other problems, and restore the computer to its initial state. However, it should be noted that reinstalling the system will empty all data on the C drive, so be sure to back up important files in advance. After reinstalling the system, be sure to install the latest Win7 drivers and follow the previous steps to troubleshoot USB port power supply issues. If the problem persists after reinstalling the system, then you may need to consider replacing the sound card or upgrading to a newer oneoperating system。
