Maddog Sound Fix v3.1.0

This release makes encrypted compatibility fingerprints available to the community and simplifies source admission and automatic upgrades. It does not add a new Leonardo version.

Before updating

Close Microsoft Flight Simulator and Leonardo Manager before running the installer. Normal versioned v3.0.0 output is recognized by its existing marker and can be upgraded automatically.

Older unversioned generated folders such as maddog-sound-compat-native-2024 or maddog-sound-compat-msfs2020 still require one manual move out of Community. Never delete either paid source package.

What changed

  • Encrypted fingerprints: maddog-sound-fix.exe fingerprint --output <absent-zip> creates one issue-safe outer ZIP containing a public version/hash header and age-encrypted XML, model, and offset-free Wwise evidence. The command never uploads anything. Attach only the generated ZIP—not either paid package or decrypted evidence.
  • Five-pin source identity: exact target and package versions are now identified by five representative SHA-256 pins: IA XML/PCK plus Leonardo XML/main PCK/exterior glTF. PNF, current crew, and interior model files remain operational parser inputs. Modified purchased packages remain unsupported and user-owned.
  • Simpler automatic upgrades: the installer completes and validates a hidden candidate, authorizes old versioned output through its exact name and minimal same-target marker, recursively deletes that tool-owned directory, then publishes the candidate. Current v3.0.0 marker extras remain accepted but are no longer deletion authority.
  • One executable: the separate private fingerprint collector and its workflow are removed. Installation and fingerprint collection are subcommands of the Windows CLI.

Supported versions

  • Native MSFS 2024: Leonardo 2.1.282 or 2.1.283 with Immersive Audio 1.0.0.
  • MSFS 2020: Leonardo 2.0.281 with Immersive Audio 1.0.0.

MSFS 2020 remains runtime-unverified by the maintainer. The Windows executable remains unsigned, so verify the published SHA-256 before running it.
