Arctis Sound Manager has been released in version 1.5.0.

New is real 7.1 surround for the Game, Media and Aux channels: Spatial Audio (HeSuVi) now places these channels around the listener. There is also surround passthrough to speakers, a clean stereo downmix and four new Sonar presets. Several bugs were fixed as well, including package installation on Ubuntu 24.04 / Linux Mint 22.

Added

• Real 7.1 surround for Game, Media, Aux channels: Spatial Audio (HeSuVi) now places those real channels around you.
• Surround passthrough to speakers: 5.1/7.1 receivers get channels without headphone rendering.
