Okay thanks everyone. I appreciate knowing that. They should grey it out then in Sound Preferences or the Sound Menu Bar if it's disabled...
Another weird thing is when the lid is closed my External Mic works for Siri but not for text Dictation... Sucks because I really need to do Dictation when the lid is closed. Double-checked the external mic is selected in both the dictation and the sound preferences. Weird that it works fine for other things but not Dictation.
I am having the same problem. Airpod external mic does not work for voice dictation when the clamshell is closed. This is extraordinarily frustrating. My macbook pro is connected to two external monitors when it is docked at home. Voice dictation is disabled. Tried dozens of times trying to fix this - resetUnfortunately, my external Mic also does not work with Dictation when the lid is closed. Double-checked a million times and also tried turning it off and on, deleting preferences, etc. Seems like a bug. I've reported it to Apple.
If the laptop is closed, why would the mic be active? Unless, I'm reading your question incorrectly.
Because clamshell mode refers to using it in a desktop setup with external monitor, keyboard and mouse. It's how I use my 2017 15" Pro and it works just fine, built-in speakers and mic included.
This is an issue specific to the 2019 16" MacBook Pros that we are discussing in this thread.
Has anyone figured out the best way to use Siri with lid closed and on a monitor?
I sent a feedback request to Apple.
It's definitely an inconvenience for clamshell users, but it's an important security feature considering that Macbooks are issued to students, corporate employees, and government employees. From a privacy standpoint, this inconvenience isn't something that can be necessarily solved with a software solution since software restrictions can be circumvented and typically when device privacy/security is a priority, hardware killswitches for laptop mics/cameras are a requirement.It's not a minor annoyance, it's a major annoyance, and an inconvenience that may end up damaging the laptop unless I completely rearrange my desk and maybe replace the monitor stands so it doesn't have to be tucked under one of them.
I consider this a design flaw, unless Apple states somewhere why this is necessary.
I've had laptops where there was a hardware WiFi switch, so I don't know why they can't have a hardware mic switch.
