Arctis Sound Manager has been released in version 1.2.26.

The tool manages audio settings for SteelSeries Arctis headsets on Linux, including microphone noise cancellation, external output routing and other audio features.

This release adds DeepFilterNet as an alternative noise-cancellation engine alongside RNoise. Several SteamOS compatibility issues were also fixed that occurred after system updates wipe the root filesystem.

Added

• DeepFilterNet noise-cancellation engine: Users can now select between RNoise and DeepFilterNet for microphone noise suppression. The application automatically downloads the LADSPA plugin if needed to ~/.ladspa and supports glibc-based systems (x86_64, aarch64, armv7) including immutable Linux distributions.

Fixed

• SteamOS compatibility: Resolved three critical issues occurring after system updates that wipe the root filesystem:
  • GUI no longer crashes when pulsectl dependency is missing
  • Dependency installer now uses pip install --user for Python modules, surviving OS updates
  • Made noise-suppression-for-voice plugin optional rather than a hard requirement; DeepFilterNet serves as an alternative
