Matrix Voice microphone range is an excellent piece of hardware. Will the Mycroft create an install script as they’ve done with other hardware?
Even if not, might be worth trying to get running so you can see what issues might be run into. Who knows, it might even just work out of the box.
I can confirm it doesn’t work right out of the box.
You’re welcome to have a look at the existing Picroft script and see how the install scripts are done for existing hardware, and have a go at creating one for Matrix Voice.
