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.
