Steam Audio Isolator wurde in den Versionen v0.4.0 und v0.4.1 veröffentlicht.

Das Flatpak-Tool nutzt PipeWire, um den Ton ausgewählter Quellen wie Spiele gezielt an Steam-Ziele (z.B. für Streaming oder Voice-Chat) weiterzuleiten, ohne dass der restliche Systemton mitläuft.

Neu in v0.4.0: eine Multi-Game-Routing-Einstellung, die GUI wechselt von PyQt5 auf PyQt6, außerdem gibt es etliche Fixes für die Erkennung von Wine/Proton-Streams. v0.4.1 behebt kurz darauf den Installationspfad der gebündelten PipeWire-1.6.10-Bibliothek im Flatpak.

Änderungen in v0.4.0:

Added

• Multi-game routing preference: route all selected games or only one focused game, optionally by preferred title, with a fallback to the newest active game process.

Fixed

• Game detection now reads missing process metadata from the PipeWire client object, restoring classification for Wine/Proton streams.
• Wine/Proton streams that expose only an application name are now classified as games.
• Channel labels for output ports now use the real channel names instead of port-ID parity, which had mislabeled both Wine channels as “Right”.
• Audio sources and Steam destinations no longer vanish when the bundled PipeWire client talks to a newer host daemon, because malformed pw-dump output is now repaired.
• The application log now rotates instead of growing without bound.
• The login autostart portal call now sends correctly typed arguments.
• Start-minimized-to-tray works even when the tray host is hidden or starts late.

Changed

• The GUI moved from PyQt5 to PyQt6.
• The Flatpak runtime moved to Freedesktop/KDE 25.08 and 6.11, and the bundled PipeWire client was updated to 1.6.10.
• The pydbus/PyGObject dependency was removed in favor of direct QtDBus portal calls.
• Minimum Python is now 3.10.
• Current Routes is now a section of the Audio Routing tab rather than its own tab.
• The Audio Routing tab uses a vertical splitter between its sections.

Änderungen in v0.4.1:

Fixed

• The Flatpak now installs the bundled PipeWire 1.6.10 client library to /app/lib instead of /app/lib64, a path the Flatpak loader doesn’t search. As a result, pw-dump and pw-cli now use the bundled 1.6.10 library instead of the runtime’s 1.4.9.
