The drivers of [ReSpeaker Mic Hat](https://www.seeedstudio.com/ReSpeaker-2-Mics-Pi-HAT-p-2874.html) and [ReSpeaker 4 Mic Array](https://www.seeedstudio.com/ReSpeaker-4-Mic-Array-for-Raspberry-Pi-p-2941.html) for Raspberry Pi.
### Install seeed-voicecard
Get the seeed voice card source code. and install all linux kernel drivers
```bash
git clone https://github.com/respeaker/seeed-voicecard
cd seeed-voicecard
sudo ./install.sh
sudo reboot

While the upstream wm8960 codec is not currently supported by current Pi kernel builds, upstream wm8960 has some bugs, we had fixed it. we must it build manually.
Get the seeed voice card source code.

### with Google Assistant
if you run the assistant but the playback is speed up considerably, try to configure alsa:
```bash
sudo cp asound.conf /etc/asound.conf
```
If the alsa configuration doesn't solve the issue, try to use pulseaudio. See [#4](https://github.com/respeaker/seeed-voicecard/issues/4)
Enjoy !
