7.1-Channel PCIe Sound Card

The Weastlinks CM8828 adds 7.1-channel audio to a desktop PC through a PCI Express 1.1 slot. It uses the C-Media CMI8828 controller paired with a CM9882A codec to deliver 24-bit playback at sample rates up to 192 kHz. The card provides six analogue jacks for line-in, microphone, front, rear, centre/subwoofer and side surround outputs. It is suited to users who want multichannel sound without using USB or integrated audio.

For Home Theatre And Gaming Builds

This card fits builders assembling a home-theatre PC or a gaming rig that needs discrete 7.1 analogue outputs and ASIO driver support. The embedded 8051-based MCU handles HD Audio command transcoding, and the Xear software suite adds vocal effects and surround processing. Buyers who only need stereo output, lack a free PCIe slot, or require digital S/PDIF connections should consider other options.

CMI8828 Chipset With 100 dB SNR

The CMI8828 chipset defines the card’s core performance, delivering a signal-to-noise ratio of 100 dB and harmonic distortion of -85 dB on playback and -90 dB on recording. These figures determine whether the card meets the fidelity needs of a given system. The board includes a standard-height metal bracket and a driver CD for installation.

Questions about this item

Should I pick the 7.1-channel version or a 5.1 setup for my home theatre?

The card outputs 7.1 channels and is compatible with 2.1 and 5.1 speaker systems, so you can use it with any of those configurations.

What does the 192 kHz / 24-bit spec mean when I'm actually gaming or watching movies?

It supports sample rates from 44.1 to 192 kHz at 24-bit depth, giving high-resolution playback and recording for games, movies and music.

The card uses PCI Express 1.1 — will that limit audio quality or channel count on a modern motherboard?

PCIe 1.1 provides enough bandwidth for the full 7.1-channel, 192 kHz / 24-bit stream, so the interface does not cap the audio performance.
