Pixel 1 camera app error "cant record audio another app is using the mic"

[Android Central Question]

My I'm attempting to record video on my pixel 1 and for some reason, I get the error "can't record audio, another app is using the mic." Yet I have no other apps open nor does any other app have permission to use the mic. Another odd thing is that it works sometimes, but others it gives this error no matter how many times I restart it

The phone has permission to use the mic, for starters. Plus any apps you've installed like voice recorders.

You could always try to reflash the ROM (but back everything up first - unlocking the bootloader wipes the phone). ROM images and instructions are at Google | Factory Images for Nexus and Pixel Devices. (And if you do that, install TWRP, to make backing up a simple one-step process.)
