  • Support for tabbing between AU controls has been substantially improved.

  • To avoid negatively impacting VoiceOver's guidance, when VoiceOver is on, adjustments made to the “System Speech” special source (say that three times fast) are now disabled, as are adjustments made to default output device. When this occurs, a visual indication (⚠️) is shown in SoundSource's main window.

  • A launching crash which would occur when an in-use Audio Unit plugin was removed from the system has been fixed.

  • When multiple devices with identical names are present, device changes are now better handled.

SoundSource 4.0.2

Released on April 11th, 2019

  • Previously, audio from certain sites (including SoundCloud.com and Splice.com) might not be correctly adjusted if it was playing in a second audio-producing tab in Chrome. This now works as expected.

  • SoundSource's audio redirection back-end has been modified to only re-direct audio headed for the default system output. This means an app which has its own output selector will not be redirected, if that selector is set to a non-default device. As well, SoundSource's default is now a “Don't Redirect” audio option. For nearly all users, everything should continue to work just fine. For a few users, things should now work as they previously expected.

  • All of SoundSource's volume sliders have been adjusted to better match the system's volume curve.

  • Audio adjustments now sound better when the system output device changes, thanks to some quick and clever audio fades.

  • The interface now better explains how a user should proceed when they have no applications in their list for per-app control.

  • The level meter is now dimmed when a source is muted.

  • Some Audio Unit plugins which did not previously load their interfaces properly now will.

  • Improvements have been made to better handle toggling VoiceOver off or on.

  • Rare crashes on slower machines are now avoided, thanks to arcane changes to the dispatch queue.

  • Other crashes related to misbehaving Audio Units have been worked around.

  • SoundSource's installation procedure has been slightly modified, to better follow standards set by other Rogue Amoeba apps.

  • In order to prevent both audio issues and possible crashes, SoundSource now specifically works to avoid any interference with other audio adjustment software , such as “Boom” or “menuBUS”.

  • The Home app is currently not compatible with SoundSource, and so is now excluded from SoundSource's list of Running Applications.

  • Tidal has been removed from SoundSource's default apps list, as their “hog mode” doesn't play well with, well, much of anything else.

  • An issue were SoundSource could incorrectly apply multiple volume adjustments to input devices has been corrected.
