Maintenance release for the recently upgraded audio control utility. ($39 new, free update, 41.8 MB, macOS 14.5+)
You must run macOS Sonoma or later to install this update. This means that several desired items such as Mail Plugins are eliminated after Ventura resulting and partially disabling features in such Apps as HoudahSpot and DevonThink. To the best of my knowledge Apple has not so far provided any solutions or workarounds for these issues.
There have been multiple reports of various issues with SS 5.7.1 in a forum I follow, Audio Science Review. In my case it breaks AudioMIDI and REW (Room EQ Wizard). I cannot output sound on any channel other than left and right to my AVR over HDMI when Sound Source is running. Quit SoundSource and all works as before. Never had any problems with previous versions (I only updated when moving to Sequoia).
