Arctis Sound Manager has been released in version 1.2.34.

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

Shortly after version 1.2.33, which fixed a critical SteamOS audio bug, this release brings two more fixes: applications not recognized by the system would incorrectly remain stuck on the headset’s direct output instead of being routed to Game, Chat, or Media channels. It also eliminates a stutter during channel switching caused by the Home page rebuilding the application list too often.

Fixed

• Applications stuck on headset output: Applications not recognized by name would remain on the headset’s direct output rather than being routed to Game, Chat, or Media channels. The system now properly distinguishes between unrecognized apps and intentionally placed ones. (Reported via Discord)
• Channel-switching stutter eliminated: The Home page was rebuilding application tags and the “other applications” list twice per second, causing stuttering during drag operations. UI elements now only update when their contents actually change. (Contributed by @Denkiyaa, #187)

Changed

• Expanded CI test coverage: Continuous integration now runs the complete test suite of 1,400+ tests across routing, mixer, audio graph, and bug reports - previously only a single test file ran. This change caught five failing tests related to the Media channel’s surround chain that had gone undetected.
