MacOS 15.2 Brings More Audio Bug Fixes

Apple has just shipped their most recent major update to MacOS 15 (Sequoia), with MacOS 15.2. This update once again brings important audio-related bug fixes to the operating system. Those fixes on Apple’s end lead to several improvements when using our products:

Muting when capturing audio playing to aggregate and multi-output devices
When capturing audio that is being played to an aggregate audio device or a multi-output audio device, it will now always correctly mute as requested.
For: Airfoil Audio Hijack Loopback Piezo SoundSource

Voice chat audio no longer doubled
Another MacOS muting issue has also been sorted by Apple. As a result, using a voice chat application like FaceTime will no longer result in doubled audio while running SoundSource.
For: SoundSource

Capturing from Music.app when it’s streaming via AirPlay
Changes Apple made in 15.2 make it possible for our apps to capture audio from Music.app even while it’s streaming audio via AirPlay. An update for Piezo is still needed to handle this, and will be released in the near future.

Muting while capturing from System AirPlay Receiver
Audio now mutes as expected when capturing from System AirPlay Receiver and other unusual sources.

Audio adjustments of Music.app when streaming via AirPlay
When streaming from Music.app to local and AirPlay speakers simultaneously, SoundSource’s features like volume control, redirection, and effects will once again apply to audio routed to the Mac’s default output.
For: SoundSource
