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.
|
|
```
|
|
git clone https://github.com/respeaker/seeed-voicecard
|
|
cd seeed-voicecard
|
|
sudo ./install.sh
|
|
reboot
|
|
```
|
|
|
|
Check that the sound card name matches the source code seeed-voicecard.
|
|
|
|
```
|
|

Next apply the alsa controls setting
|
|
```
|
|
sudo alsactl --file=asound.state restore
|
|
```
|
|
If you want to change the alsa settings, You can use `sudo alsactl --file=asound.state store` to save it.
|
|
|
|
Test:
|
|
```
|
|
arecord -f cd -Dhw:1 | aplay -Dhw:1
|
|
```
|
|
|
|
### with Google Assistant
|
|
if you run the assistant but the playback is speed up considerably, try to configure alsa:
|
|
|
|
```
|
|
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)
