Firstly, get an updated kernel 4.9 :
|
|
```
|
|
sudo apt update
|
|
sudo apt dist-upgrade
|
|
sudo apt install git rpi-update bc dkms
|
|
sudo BRANCH=next rpi-update
|
|
sudo reboot
|
|
```
|
|
|
|
Install matching kernel header files(come from https://www.raspberrypi.org/forums/):
|
|
eg. Get your kernel verson "uname -r", then
|
|
```
|
|
wget https://www.niksula.hut.fi/~mhiienka/Rpi/linux-headers-rpi/linux-headers-4.9.13-v7%2B_4.9.13-v7%2B-2_armhf.deb
|
|
```
|
|
Next, 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 http://git.oschina.net/seeed-se/seeed-voicecard
|
|
cd seeed-voicecard
|
|
sudo make all install
|
|
```
|
|
Next, copy then voice card overlay to boot dir, then apply it.
|
|
```
|
|
sudo cp seeed-voicecard.dtbo /boot/overlays
|
|
sudo reboot
|
|
sudo modprobe wm8960
|
|
sudo dtoverlay seeed-voicecard
|
|
```
|
|
Check that the sound card name matches the source code seeed-voicecard.
|
|
|
|
```
