ALP221e – support

ALP221e is a low-profile linear PCM sound card with one stereo AES3 input and one AES3 output. It is designed to be used under Windows (DirectSound / Wasapi / Asio) or Linux (Alsa). 

Drivers for Windows

  • The “ALPX-kit” package for Windows allows installing the following components:
  • Driver with Wasapi interface
  • ASIO driver with its ASIO control panel (CPL)
  • Digigram ALP-X Manager application (I/O levels, I/O routing matrix, clock selection,…)
  • Supported Windows flavors: Windows 10 from version 20H2


    ALP221e operates under Linux from the 64-bit Kernel 4.1x onwards.

      The Alsa driver for Linux is supplied as a DKMS package, which can therefore be used to compile the driver for the target Linux distribution used.

      In case you experience difficulties in compiling and installing the driver for your distribution, contact us:! We propose an additional paying service to help you install your driver package.
