How do I get the Google AIY Voice HAT installed so that MMM can use it?

Hi @Sean

Thankyou for helping me.

Hmm:

pi@magicmirror:~ $ arecord -l
**** List of CAPTURE Hardware Devices ****
pi@magicmirror:~ $ aplay -l
**** List of PLAYBACK Hardware Devices ****
card 0: ALSA [bcm2835 ALSA], device 0: bcm2835 ALSA [bcm2835 ALSA]

So the hat doesn’t appear at all as it is.
I guess I could get the AIY image, and start with that instead?
Then it should have the right setup.

Sorry, I have no experience of that HAT, so I don’t know its normal or not.

So @sdetweil and @Sean

I started over, installed the last stretch.
Followed the guide on the link from @sdetweil , and Weheee:

pi@raspberrypi:~ $ aplay -l
**** List of PLAYBACK Hardware Devices ****
card 0: sndrpigooglevoi [snd_rpi_googlevoicehat_soundcar], device 0: Google voiceHAT SoundCard HiFi voicehat-codec-0 []
  Subdevices: 0/1
  Subdevice #0: subdevice #0
pi@raspberrypi:~ $ arecord -l

  Subdevices: 1/1
  Subdevice #0: subdevice #0
pi@raspberrypi:~ $

Now I’ll go on, and start over with Magicmirror :-)

There could be one problem. Your mic and speaker now have same id card 0, device 0 When my module try to close the mic(plughw:0,0) to output sound, the speaker(plughw:0,0) will be closed together at same time, so error will occur.
I heard there is a way to assign different id or alias to devices, but don’t know how to do.

Ok, so it doesn’t use the subdevices to distinguish them, I guess it’s google here I come :-)
