Я пытаюсь установить Google Assistant SDK на rpi, перейдя по этой ссылке "https://developers.google.com/assistant/sdk/guides/service/python/embed/run-sample"
При выполнении этой команды googlesamples-assistant-pushtotalk --project-id my-dev-project --device-model-id my-model
я получаю:

Вопрос был рассмотрен и на него дан ответ здесь: https://stackoverflow.com/questions/43958779/google-assistant-sdk-on-raspberrypi-3-sounddevice-portaudioerror
Я протестировал это решение, и оно работает и у меня.
Просто измените .asoundrc
на:
pcm.!default {
type asym
playback.pcm {
type plug
slave.pcm "hw:0,0"
}
capture.pcm {
type plug
slave.pcm "hw:1,0"
}
}
