Sound is usually more sensitive, yes. But even if there is a physical switch on the laptop, only very exotic smartphones have them.
Also, loudspeakers can act as microphones, too.
In other words, paranoia gets exhausting in modern times.
(And my smartphone has a replacable battery for that reason to at least sometimes enjoy potentially surveillance free time)
My Pinephone has a switch for the microphone and also my Pinebook Pro laptop. But I also would agree that this is exotic hardware.
Well i have Pinebook Pro and it's pretty much abandonware, pine doesn't do any software and OSS lacks maintainers, nobody want's it, e-waste laptop. Take it as you will.
"But I also would agree that this is exotic hardware."
No shit. How is the current state btw?
I suppose still not ready to be a daily driver to replace my normal phone?

I'd say that depends on your definition of daily driver and/or how much compromises you're willing to take. I occasionally see members at my larger hackerspace running around with those or other seemingly "unfit" hardware and not complain too much about it ;)
