Target Build & Purpose

The SEDNA SE-PCIE-SC-10 is a PCIe 1x sound card that adds 7.1-channel audio to a desktop PC. It uses the CMedia 8828 chipset paired with the CM9882A to deliver 24-bit 192KHz playback and recording with a 92dB signal-to-noise ratio. The card includes an SPDIF bracket for digital optical input and output alongside standard 3.5 mm analog jacks. ASIO driver support is provided for low-latency audio work.

Ideal User & Limits

This card suits home-theatre PC builders, music enthusiasts and mixing professionals who need multi-channel analogue output and digital SPDIF connectivity without using a USB device. It is not for systems that lack a free PCI Express x1 slot or for users who require higher signal-to-noise figures than 92dB. Buyers needing more than 7.1 channels or different digital interfaces should look elsewhere.

Deciding Specification

The single specification that determines fit is the PCIe 1x interface combined with the CMedia 8828 chipset delivering 7.1 channels at 24-bit 192KHz and 92dB SNR; verify your motherboard has an available PCIe x1 slot and that the channel count and fidelity meet your project requirements.

Questions about this item

How does the 92 dB signal-to-noise ratio affect real-world listening?

A 92 dB SNR keeps background hiss low enough that quiet passages in music or film remain clean when played through typical desktop speakers or headphones.

What does the PCIe x1 interface limit in practice?

The x1 lane provides ample bandwidth for 7.1-channel 24-bit 192 kHz audio, so the slot does not restrict playback or recording quality.

What does the card need to fit and mount in a PC?

It requires a standard-height PCIe x1 slot and a free rear bracket for the included SPDIF daughter board.
