MacOS users find similar functionality in the System Preferences under Sound. The Output tab lists available devices, and the "+" button lets users aggregate devices for simultaneous playback. For example, pairing AirPods with a HomePod creates a multi-device output. However, macOS lacks native per-app audio routing, a limitation often addressed by third-party tools like SoundSource. A practical workaround is using the Audio MIDI Setup utility to create multi-output devices, though this is more technical and less intuitive than Windows’ approach.
Linux distributions vary, but environments like GNOME or KDE offer robust audio management. In GNOME, the Sound settings panel lets users switch outputs per application via the Output Device dropdown in individual app settings. KDE’s Plasma desktop takes this further with Phonon, a backend system enabling precise control over audio streams. For example, you can mute system sounds while playing media uninterrupted. A caution: Linux’s flexibility comes with complexity, and users may need to tweak PulseAudio or PipeWire configurations for advanced setups.
Across all platforms, a common challenge is latency when splitting audio, especially in real-time applications like music production. Ensuring all devices share the same sample rate (e.g., 44.1 kHz or 48 kHz) mitigates this. Additionally, wired connections generally outperform wireless ones in stability, making them preferable for critical tasks. While system settings provide a solid foundation, combining them with hardware solutions like audio interfaces or software like Voicemeeter (Windows) can further enhance control. Ultimately, mastering these settings transforms how you interact with audio, tailoring it to your specific needs.
