Hello all!
I’ve been trying to get the Audio Codec Breakout board connected to the Raspberry Pi (Attempting on the W, Pi 3 and Pi 4) and functioning but am having some issues. Given that there are no direct drivers for the Raspberry Pi, I’ve been following the guide over at https://learn.sparkfun.com/tutorials/sp … udio-codec.
My pinout is pulled from the guide here:
WM8960 Stereo CODEC (I2S)
Pin # GPIO Function
12 GPIO 18 (PCM_CLK) BCLK
35 GPIO 19 (PCM_FS) DAC-LRC
38 GPIO 20 (PCM_DIN) ADC-DAT
40 GPIO 21 (PCM_DOUT DAC-DAT
// as well as general i2c setup on pins 03 and 05, as well as 3v3, 5v and gnd
// also worth noting, I'm getting the POWER led on when power is supplied
With that in mind, I’m following the guide and using the drivers found at https://github.com/waveshare/WM8960-Audio-HAT.
The install goes as expected and completes. however, I’m still unable to get any audio output. Here’s some of my findings from the logs/configurations:
