The latest generation stereo sound card designed for the most demanding professional audio applications.
ALP222e
Same quality, same high standards. A new technology core for this new cards range will push back the limits, offer enhanced performances and simplify users’ daily routines with ALP-X sound cards.
ALP222e is a low profile PCIe stereo sound card designed for operating in continuous 24/7/365 use-environments, as part of professional audio applications based on Windows or Linux operating systems. The card offers analog and digital audio connectivity, and features an on-board 8×8-channel mixer that allows for the routing and mixing inputs to the outputs.
The low latency drivers are multicard (up to 8 ALP cards) and multi-client.

Q&A
Sound cards
Which Linux Distribution are supported for sound cards ?
LoLa soundcards and multichannels VX/PCX series are supported on every Linux distribution, as the ALSA driver is part of the kernel.
The VX and PCX stereo cards have precompiled versions for Debian, Ubuntu, CentOs, Fedora, and OpenSuse-based distributions. For the LX series, the following distributions are supported: Ubuntu LTS / Debian LTS / CentOS 7.
For other Linux distributions, we propose a service for providing an adequate compiled and installable driver package. UAX and Cancun series will work on every Linux distribution.
My sound card is not detected by Windows
Make sure that you downloaded the lasted driver on our website. Indeed, from time to time we have to make component updates that require a new driver.
