変更点

ARK Plugin Updated to 12.2.4
The ARK plugin, which powers SoundSource’s audio handling, has been updated to version 12.2.4. This contains several improvements, including preventing a rare issue where ARK could incorrectly appear in the Dock, as well as reducing CPU usage and fixing occasionally inaccurate level meters.

New “Spoken Content” Special Source
On MacOS 15 (Sequoia), the new “Spoken Content” special source replaces the previous “Text to Speech” special source. It captures audio from the “Accessibility” settings “Spoken Content” area, as well as from apps which play text-to-speech audio (triggered by the “Start Speaking” command in the “Speech” menu) via the system.

Sound effects from Siri and Dictation will no longer be muted unexpectedly, correcting a regression introduced in 5.8.2.

Bluetooth devices are no longer kept active when no audio is being played, enabling improved functionality for features such as auto-device switching. This adjustment should have the pleasant side-effect of extending battery life for Bluetooth-enabled devices.

Duplicate entries of the same Bluetooth device will no longer incorrectly appear in the device selector..

Non-bundle type Steam games (such as “Transport Fever 2”) are now better supported, with audio captured as expected, and correct application icons shown.

The “Bitwig Studio” application should now appear normally in SoundSource, rather than showing as a command-line process “BitwigStudio”.

The volume slider focus ring now correctly follows the knob when it moves as a result of the “Volume Overdrive” effect.

Many of SoundSources automation Shortcuts have been migrated to use the new AppIntents framework. Old Shortcuts will continue to work, but will have a deprecation notice.

SoundSource 5.8.3 Is for MacOS 14.5 and Higher
This variant of SoundSource supports MacOS 14.5 and higher. On MacOS 11 through 14.4.1, a different variant is automatically used, with no action required on your part.
