PCI Express x1 5.1‑channel audio card

This PCI Express x1 sound card uses the C‑Media CMI8738‑6CH LX chipset to add 5.1‑channel output to a desktop PC. It targets builders who need multichannel audio without occupying a legacy PCI slot. The board provides digital stereo and surround playback for home‑theatre or gaming speaker sets. Installation requires a single free PCIe x1 lane.

5.1 channels at 44.1 kHz 16‑bit with 100 dB SNR

The card delivers 5.1 channels at 44.1 kHz sampling and 16‑bit depth, with a signal‑to‑noise ratio of 100 dB. It comfortably drives 2.0, 4.0 or 5.1 speaker configurations for movies and games. Headroom runs out for high‑resolution formats above 44.1 kHz or bit‑depths beyond 16‑bit. Professional recording or multi‑stream production will exceed its capabilities.

C3DX 3D audio, 10‑band EQ

Bundled software enables C‑Media C3DX HRTF‑based 3D positional audio for immersive headphone listening. A 10‑band equaliser offers 12 preset modes plus 27 global environment effects to tailor sound signatures. These tools enhance movies and games but do not add hardware DSP or additional I/O ports.

Questions about this item

Will the CMI8738-6CH LX card work in an older motherboard that only has PCI slots?

The card uses a PCI Express x1 interface, so it requires a PCIe slot and will not fit a legacy PCI slot.

How can I verify the 100 dB SNR and 16-bit 44.1 kHz output are active after installing the driver?

Open the C-Media control panel, enable the 10-band equalizer with one of the 12 presets, then play a test tone; the panel shows the active sample rate and bit depth.

Does the box include speaker cables or only the low-profile bracket?

The card ships with a low-profile bracket; analogue cables for 5.1 speakers are not included.
