Arctis Sound Manager has been released in version 1.6.3, a few days after version 1.6.2.

The headset settings (sidetone, mic volume, volume limiter, sleep timer, ANC) now live on a dedicated Headset page. Also fixed were a D-Bus connection leak that crashed the desktop session after 15 minutes and Sonar audio problems on SteamOS.

Added

• Headset settings reorganization: Moved the headset’s own settings (sidetone, mic volume, volume limiter, sleep timer, ANC) from Settings to a dedicated Headset page with organized cards and tiles.
• Arctis Nova Pro Wireless: The app now reads existing base station settings before sending commands, preserving values set outside ASM.
• Windows reverse-engineering tool: Users can now record what SteelSeries GG sends to capture device-specific settings data.
• Enhanced probe output: The asm-cli tools probe command now displays detailed field-by-field headset information.

Fixed

• SteamOS audio issue: Resolved Sonar audio problems on SteamOS by identifying ASM nodes the way WirePlumber’s own do.
• Desktop session crash: Fixed a D-Bus connection leak that was causing session crashes after 15 minutes by failing to close connections.
• H.264 parsing error: Added missing dependency checks and installation for the h264parse plugin.
• Sidetone auto-activation: Corrected unwanted sidetone activation on Nova Elite and Nova Pro Omni models.
• Setting synchronization: Fixed timing issues between reading headset values and sending startup commands.
• DAC screen display: Resolved EQ mode labeling and city name rendering issues.
