Macs with T2 chip treat the headphone jack and the internal speakers as separate devices
Apple’s recent Macs include enhanced built-in good devices, according to Rogue Amoeba who are well-known good specialists as well as creators of character good software for macOS as well as iOS.
The magic of the T2 chip
Both the novel Mac mini as well as MacBook Air receive got ii distinct good devices independent from i another: the headphone jack as well as the internal speakers. In fact, all Macs alongside the T2 chip present this behavior, including iMac Pro as well as 2018 MacBook Pro models.
On older Macs, the headphone jack as well as the internal speakers are essentially dissever ports on a unmarried output device as well as alone i of these ports is allowed to live on active at a time. Because of this, good tin plow over notice live on sent to either the built-in speakers or the headphone jack, exactly non to both. As well, if anything is connected to the headphone jack, the OS shuts off the built-in speaker completely.
With T2 Macs, in that place are genuinely ii distinct output devices. The headphone jack as well as the internal speakers are dissever devices, completely independent from i another.
You tin plow over notice create out built-in good devices through System Preferences → Sound → Output. Now, contrast this alongside older Mac models that allowed alone i of these ports to live on active at a time.
If you lot ain a Mac alongside the T2 safety chip, you lot tin plow over notice simultaneously post good to both the built-in speakers as well as your headphones connected to the 3.5mm port. With older Macs, good tin plow over notice live on routed to either the built-in speakers or the headphone jack, exactly non to both.
Why you lot should care
Paul explains how this is useful:
Perhaps the close obvious means to receive got wages of these ii devices is to post the Mac’s good effects to the built-in speakers, piece using the headphone jack for music as well as other audio. This way, you’ll never live on jarred out of a skillful listening session past times an mistake message beep blaring over your music.
To post the macOS good effects to the device speakers, larn to System Preferences → Sound → Sound Effects, as well as then click the popup card adjacent to “Play good effects through” and gear upwardly the good effects to the built-in speakers. Next, click the Output tab as well as brand certain your headphones are beingness used for the measure good output device.
As mentioned, macOS delists the headphone port if cipher is plugged inwards to it—make certain that your headphones or speakers are plugged inwards hence they seem inwards System Preferences.
macOS’s auto-switching that prioritizes the headphone jack even hence industrial plant similar you’d expect. And if you lot piece of job headphones alongside a built-in microphone, macOS volition recognize it every bit an input device.
