1 These new Macs mean powerful audio routing is possible with nothing more than a pair of headphones. With older Macs that effectively only had a single audio output device, however, you needed to have external audio devices to do any sort of routing. More Powerful Audio Control, With Audio Hijack and Loopbackīoth the aforementioned Audio Hijack and our audio routing tool Loopback are useful for working with multiple audio devices at once. Make sure your headphones or speakers are being used for the standard audio output device (as configured in the “Output” tab), and you’ll be all set. There, you can configure the “Play sound effects through” setting to use the device speakers set the Sound Effects. To split things up, head for the “Sound Effects” tab in the Sound System Preference. This way, you’ll never be jarred out of a good listening session by an error message beep blaring over your music. Perhaps the most obvious way to take advantage of these two devices is to send the Mac’s sound effects to the built-in speakers, while using the headphone jack for music and other audio. Send Sound Effects to the Built-In Device Below, you can see this in action, with Audio Hijack being used to route audio from iTunes to a pair of external headphones while audio from Spotify plays to the built-in speakers. This change means it’s possible to send different audio sources to each output. The headphone jack and the internal speakers are separate devices, completely independent from one another.
With these new Macs, there are actually two distinct output devices. As well, if anything is connected to the headphone jack, the OS shuts off the built-in speaker completely. Because of this, audio can be sent to either the built-in speakers, or the headphone jack, but not to both.
On older Macs, the headphone jack and the internal speakers are essentially separate ports on a single output device, and only one of these ports is allowed to be active at a time. Better still, they include a nice little surprise when it comes to audio: two distinct audio output devices! Output Devices on Old Macs vs. While the prices have unfortunately crept up, these are solid updates worthy of consideration by anyone looking for a new desktop or laptop. Late last month, Apple finally shipped updates to two of the most neglected Macs, the Mac Mini and MacBook Air. Posted By Paul Kafasis on November 9th, 2018
