Arctis Sound Manager has been released in version 1.4.26.

Following version 1.4.25, this update fixes a daemon freeze on wake from suspend (particularly on the Nova Pro Omni), caused by a threading deadlock during headset re-enumeration. Also fixed: chat audio routed to external devices now stays in stereo instead of collapsing to mono, the aux channel toggle properly triggers daemon reconfiguration again, ASM’s internal PipeWire nodes no longer show up in the mixer, the aux channel correctly appears in the tray’s output routing menu, and external output devices no longer briefly play through the headset at startup. New: Media and Aux channels can now ride along on the non-chat side of the ChatMix knob via toggles.

Fixed

• Daemon freeze on wake from suspend: Resolved threading deadlock issue affecting headset re-enumeration, particularly on Nova Pro Omni. The problem involved three threads competing for locks; the solution moved sleep operations outside critical sections and deferred detection tasks to prevent blocking.
• Chat channel audio format: Chat routed to external devices now maintains stereo instead of collapsing to mono, as ASM now manages its own link configuration.
• Aux channel toggle: The aux_enabled setting now properly communicates with the daemon. Previously, the toggle saved to disk but failed to trigger daemon reconfiguration due to a registry lookup issue.
• Internal PipeWire nodes visibility: ASM’s internal routing nodes no longer appear in the mixer’s application list.
• Output routing menu: Aux channel now appears in the system tray’s Output Routing menu when enabled.
• Output channel startup routing: External output devices no longer briefly play through headsets at startup; the Output channel now owns its link and implements delayed fallback logic.

Added

• ChatMix knob expansion: Media and Aux channels can now ride along with the knob’s non-chat side via toggles, while Game and Chat remain fixed configuration sides.
