ESP32 Forum

Hello,

I'm able to compile and download the downmix pipeline example to my ESP32-LyraT-Mini but

esp_err_t ret = audio_event_iface_listen(evt, &msg, portMAX_DELAY);

never returns.

I tried other examples (pipeline_a2dp_sink_stream, element_sdcard_mp3, pipeline_sdcard_wav) which work fine.

I wonder if all links are set properly:

const char *link_mix[2] = {"mixer", "i2s"};
audio_pipeline_link(pipeline_mix, &link_mix[0], 2);

const char *link_tag[3] = {"file", "wav", "raw"};
audio_pipeline_link(pipeline, &link_tag[0], 3);
