Rogue Amoeba has issued SoundSource 5.1.1, a maintenance update that brings initial compatibility with macOS 11 Big Sur, along with improvements and bug fixes to the audio control utility. The release also updates the Audio Capture Engine to version 11.5 (with initial Big Sur compatibility), returns Text to Speech audio capture support (fixing a regression in version 5.1), fixes an issue with incorrectly calculated bandwidth settings to improve the Headphone EQ sound, returns the capability to add multiple Special Sources to Favorites, and ensures that the last-open item is correctly remembered between launches in all cases now.
Shortly after this release, Rogue Amoeba issued version 5.1.2 with backend updates to improve compatibility with the new M1 chip-based Macs. SoundSource 5.1.2 also ensures that the blue System “accent” color is no longer improperly ignored in 10.14 Mojave and 10.15 Catalina.
