### 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 ! Enjoy !
