Arctis Sound Manager has been released in version 1.4.5, shortly after the recently covered version 1.4.4.

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

This release comes from a deliberate hunt for hardware and system failures the developer doesn’t own, plus three user-reported bugs. It adds the ability to choose which headset to drive when several Arctis units are plugged in, fixes a string of SteamOS/Distrobox audio issues, and closes several D-Bus security holes in the settings.

Added

• Choose which Arctis ASM drives when several are plugged in. Settings now lists the Arctis units actually detected and remembers the one to drive. An unplugged preferred unit falls back to the other headset rather than to nothing.
• The Nova Elite answers its own status request, ending blank status rows from startup until each control had reported once.
• A bug report says which kernel driver holds the USB interface - relevant from Linux 7.3 on, where an in-kernel hid-steelseries driver will bind to the same interface on 25+ models.

Fixed

• The .deb on the releases page could not start. It shipped without Pillow, so the daemon died on a bare ModuleNotFoundError at first launch.
• Sound on SteamOS through Distrobox: the filter-chain unit never told PipeWire where ASM stages its LADSPA plugins, ASM overwrote the host’s own service file, and a PipeWire link refused on permissions retried forever instead of regenerating.
• Safe mode delivers the flat path it promises - the fallback channels used to still point at the equaliser nodes just removed, producing silence instead of flat audio.
• GameBuds are no longer reported as absent, even though their audio played and controls worked fine.
• The uninstaller stops breaking installs it does not uninstall - it used to stop and disable ASM’s services before asking anything.
• Your equaliser survives a repair. A damaged channel config used to be rebuilt as a flat bypass; repairs now rebuild the real curve and back up what they replace.
• Settings cannot be poisoned from outside. Values arriving over D-Bus are now checked against what each setting declares, closing a hole that allowed arbitrary data in the configuration.
