AudioScience offers drivers for a variety of Linux distributions. Due to the complex steps involved in installing and maintaining Linux system we recommend you work with a local expert to help you get up and running as quickly as possible. For help with our Linux driver, please see the Support section below.

This package supports the AudioScience HPI API. It includes kernel driver, libraries and commandline tools. It also includes scripts and metadata to create debian packages equivalent to the ones available on our Ubuntu PPA. The driver and tools are supplied as source under the GPL license. Userspace libraries are under a BSD style license. Both 32 and 64 bit kernels are supported. (Note: mixed 32 bit user / 64 bit kernel is not supported)

ALSA source includes snd-asihpi driver and firmware, however this will lag the latest HPI drivers mentioned above. Check the version in alsa's copy of hpi.h to see if it is recent enough for your needs. Notes specific to the snd-asihpi driver can be found on the ALSA wiki. Use of a recent version of ALSA is recommended.

The HPI packages include a Makefile that can be used to automatically patch a recent ALSA source tree with new HPI source, and a Makefile that will build just the snd-asihpi driver module using current kernel headers.

Add the ppa:audioscience/release to your package source list and install snd-asihpi-dkms-4 to get automatic ALSA driver updates for AudioScience cards. The PPA currently supports the following Ubuntu distribution series: 20.04 LTS (focal) and 22.04 LTS (jammy).

In a terminal window run the following commands:

sudo add-apt-repository ppa:audioscience/release sudo apt-get update sudo apt-get install snd-asihpi-dkms-4
