MacOS 15.4 Brings A Key Audio Bug Fix

MacOS 15.4 is the latest major update to MacOS 15 (Sequoia), and we’re very glad to see it. Though MacOS 15.3 didn’t include any known audio fixes, today’s update includes a key audio-related bug fix to the operating system.

Audio Playback, Particularly in Safari, No Longer Cuts Out Unexpectedly
Previously, a MacOS bug had the potential to cause cutouts when audio was being captured by another application. This was most often heard (or not heard) with Safari, when playing media in multiple tabs or windows. SoundSource users were the most impacted by this issue, but any of our audio capture products could be affected.
