I’ve found code examples on the Legato website for recording audio from the microphone, and playing it back over the speaker, but these examples use the internal codec on the WP modules. Am I correct in my understanding that le_audio_OpenSpeaker and le_audio_OpenMic use the codec internal to the module?
I’m trying to use the audio path on the mangOH that goes over the I2S and to the external codec. I’ve tried a number of different things, but I’m not getting any audio in the speaker/headphones. My recorded audio file is the duration that I’ve specified, but I just get silence when I play it back.
I found a code example for voice calls on the mangOH, but it also seems to use the microphone and speaker going through the internal codec.
Are there any code samples available which use the WM8944 codec for routing audio to/from the speaker/mic?
