You can do so by creating an aggregate or multi-output device that will treat two or more of these separate physical interfaces as a single virtual one.

Let’s say you have an Airplay device plus a USB, ethernet, or Firewire audio interface attached to your Mac, and you’d like to play the same audio on more than one of them. Aggregate devicesĪudio MIDI Setup is also helpful in creating aggregate and multi-output devices from your available audio interfaces. In some devices these options will be configurable, and in others they will not. In the configuration, you should have options for selecting the audio format (sampling rate, channel number, and bit-depth of the signal), as well as the options for specifying relative channel output levels. Your Mac’s audio devices should all be listed in the left-most column in Audio MIDI Setup, and clicking each will give you a number of configuration options for the input and output channels it hosts. When you select a device in Audio MIDI Setup, you can change the relative output or input gain of each supported channel. In this program, you will have far more control over the audio configuration of your system, and not only change audio formats, but also control the output for speakers, assign different channels to different speakers, and combine separate audio devices into one. Beyond them, you will have to look to a tool in your Utilities folder called Audio MIDI Setup. While these features so far can be convenient, they are just the basics of Apple’s audio configuration features. To get around this, you can use the Sound Effects tab to make these sounds play only on the system’s internal speakers or headphones, while other audio is piped out the USB port to your home theater.

While you might consider using the Selected Output Device (the default option) for playing sound effects, you might not want to do so if you’ve connected your Mac to a large home-entertainment system for music out of in that case, a warning Ping, Pop, or Purr sound could be intrusive. On the Sound Effects tab, for example, you can choose which device should play system alerts. In addition to this menu, the Sound system preferences pane gives you access to controls that are useful when you have multiple audio devices attached.
