Step-by-Step Procedure

1

Physical Installation of the Sound Card

• Power down the computer completely and switch off the main outlet.
• Remove the side cover plate of the system cabinet using a Phillips screwdriver.
• Locate an empty PCI or PCIe x1 expansion slot on the motherboard.
• Remove the metal slot expansion cover from the back of the chassis.
• Align the sound card edge connector with the chosen slot and press down firmly until seated properly.
• Secure the metal bracket of the sound card to the cabinet chassis using a retaining screw.

2

Connecting Peripherals & Initial Boot

• Connect the audio line-out connector (Green 3.5mm jack) from your speaker or headphones into the Green Port of the newly installed sound card.
• Connect the Microphone to the Pink Port (if testing microphone input).
• Re-attach the cabinet side panel, reconnect the power cord, and boot into Windows OS.

3

Driver Installation & BIOS Setup (If Required)

• If the onboard audio conflicts with the expansion card, restart the PC, enter BIOS/UEFI Setup (Del or F2 key), navigate to Integrated Peripherals, and set Onboard Audio to Disabled. Save and Exit.
• Log into Windows. Open Device Manager (Press Win + X → select Device Manager).
• Under Sound, video and game controllers, check for any yellow exclamation mark or "High Definition Audio Device".
• Right-click the device, select Update Driver, choose Browse my computer for drivers, and point to the manufacturer's setup directory or driver disk.
• Follow the wizard instructions to complete the installation.

4

Software Configuration & Testing

• Open Control Panel → select Sound (or run mmsys.cpl).
• Under the Playback tab, locate the newly installed sound card.
• Right-click on it and select Set as Default Device.
• Highlight the device, click Configure, select your speaker setup (e.g., Stereo, 5.1 Surround), and click Test to verify audio signal delivery.
• Switch to the Recording tab, speak into the microphone, and verify the green audio meter level fluctuates.

💡 Tip: If no sound is produced, ensure the volume is not muted in the System Tray audio icon and check that speakers are powered ON with correct source selection.

Verification & Observation Table

Check Point	Expected Result	Status (Pass/Fail)
Hardware Seating	Card firmly seated in slot & screwed to chassis	[ Pass / Fail ]
