"""Microphone picker — MIC_DEVICE in .env is a device index most people have
|
|
no way to look up short of running a script. This dialog lists whatever
|
|
sounddevice can actually see, lets you click one, and writes its index back
|
|
to .env so it survives a restart.
|
|
|
|
The index, not the name, is what gets saved: the same device is commonly
|
|
listed once per host API (MME, DirectSound, WASAPI, WDM-KS, ...) under the
|
|
same or a near-identical name, which makes a bare name an ambiguous pick that
|
|
sounddevice will flatly refuse to resolve (see audio/mic.list_input_devices).
|
|
The index is exact.
|
|
|
|
The mic is only ever opened once, at startup (see controller.run()), so a
|
|
pick made here still needs a restart before Bolt actually uses it — this
|
|
dialog just makes finding and saving the right device painless, and offers
|
|
to do the restart for you.
