Go to the Details tab and select Hardware Ids from the dropdown menu.

Most Ezhou cards use C-Media chipsets (like the CMI8738 or CMI8768). Visiting the C-Media official website is the safest way to find a stable driver. Similarly, if your card uses a VIA Envy24 chip, you should check the VIA Technologies support archive. Driver Archive Repositories

If the driver fails to install or you still have no sound, check the following:

Extract the files: Most drivers come in a ZIP or RAR format. Use a tool like WinRAR or 7-Zip to extract them to a folder on your desktop.

For users on modern versions of Windows, the Microsoft Update Catalog is a powerful tool. By searching for the Hardware ID you found earlier, you may find a generic driver signed by Microsoft that enables basic audio functionality. Installation Steps

Before you can download the correct driver, you must identify the chipset. You can do this without opening your computer case by using the Device Manager. Right-click the Start button and select Device Manager. Expand the Sound, video and game controllers section.

Run the Setup: Look for a setup.exe or install.exe file within the folder. Right-click it and select Run as Administrator.

Reseat the Card: Physical connection issues can prevent the driver from "seeing" the hardware. Power down your PC, unplug it, and firmly reseat the PCI card in its slot.

Ezhou sound cards were popular as affordable, high-performance alternatives to built-in motherboard audio. They typically utilize well-known chipsets from manufacturers like C-Media, VIA, or Realtek. Because "Ezhou" is often a branding name for a generic board design, the driver you need is usually dictated by the specific audio controller chip soldered onto the card. Identifying Your Hardware

Disable Onboard Audio: Sometimes the motherboard's built-in audio conflicts with the PCI card. You may need to enter your BIOS/UEFI settings and disable the "Onboard Audio" option.
