OULLX 4.1 PCI Sound Card 8738 Audio Adapter for Desktop PC
OULLX 4.1 Channel PCI Sound Card – Upgrade Your Desktop PC Audio
Give your desktop PC a serious audio upgrade with the OULLX 4.1 PCI Sound Card (8738 Chipset). This internal PCI sound card installs directly into your motherboard's PCI slot and delivers clear, independent 4.1-channel audio — perfect for replacing a damaged, noisy, or non-functional onboard sound card without needing a new motherboard.
Made in Mainland China.
Why Upgrade to a Dedicated PCI Sound Card?
Onboard motherboard audio can suffer from electrical interference, hardware damage, or simply underperform for music, gaming, or multimedia use. This independent sound card bypasses all of that, giving you a clean, dedicated audio solution with full duplex playback and recording capabilities.
⚠ Important Note: This sound card is NOT compatible with MSI / ASRock / BIOSTAR / Lenovo / HP / Dell or Server motherboards. Please verify your motherboard brand before purchasing.
📀 Driver Installation Required: Each package includes a CD driver. You must install the CD driver to use the sound card. Alternatively, software such as DriverGenius can be used to install the driver program.
Please use standard computer headphones only. Microphone and headphone ports are separate sockets — mobile phone combo headphones (single-jack) are not compatible.
