I have GrapheneOS on a Pixel 8, and I got Android Auto with voice recognition working about 2 months ago. Today I noticed that it isn't working any more, when I click the car button or the android auto screen voice button, it just gives a "Voice commands aren't available right now" toast message.
I tried uninstalling Android Auto, the Google App, and Speech Recognition and Synthesis from Google, and then reinstalling everything, but am still getting the same result.
Build number is 2025080600
Anyone have any ideas? Is this related to the new Graphene build?
