PCIe 5.1 sound card for low-profile builds

The EN-Labs PCIE51SOUND adds 5.1 surround audio to a desktop through a single PCI Express slot. A 16-bit decoder handles 32-bit and 64-bit processing for recording and playback. The bundled low-profile bracket fits 2U chassis where full-height cards cannot be installed. Windows 2000 through 10 are supported.

Upgrade from basic integrated audio

Motherboard codecs often lack discrete 5.1 output and hardware-accelerated DirectSound, A3D, EAX and HRTF 3D positioning. This card supplies those features through the CMI8738 chip without occupying a full-height slot. The improvement is worthwhile when surround speakers or a home-theatre receiver are already connected and the onboard audio cannot drive them.

5.1 analogue output with 16-bit headroom

Six analogue channels deliver front, centre, rear and subwoofer signals for cinema-style playback. The 16-bit decoder provides clean stereo and multichannel streams at standard sample rates. High-resolution formats beyond 16-bit or channel counts above 5.1 are not supported, so audiophile recordings or 7.1 speaker layouts will require a different solution.

Questions about this item

Will the low-profile bracket fit my 2U chassis?

The card ships with a low-profile bracket designed for 2U cases; swap the full-height bracket if your chassis needs it.

Which step do installers often miss when setting up the CMI8738 card?

After inserting the card, disable the onboard Realtek High Definition Audio in Device Manager or the new adapter stays silent.

What ongoing upkeep does the 5.1 sound card require?

No scheduled maintenance; keep the driver current and clean the rear-panel ports with compressed air if dust builds up.
