how to record and play at same time (AUD-4795)

[ArvinHou]

I want to use codec->i2s->raw and raw->i2s->codec at same time. I have no idea. 1.test codec->i2s-raw OK Raw data is sent to the computer by UDP and played without any issues 2.test raw->i2s-codec OK Raw data is receive from computer by UDP and played without any issues 3.use at same time only raw->i2s-codec works OK I create 2 pipeline

audio_pipeline_register(pipeline, i2s_stream_reader, "i2s");
audio_pipeline_register(pipeline, raw_read, "raw");

ESP_LOGI(TAG, "[3.4] Link it together [codec_chip]-->i2s_stream->raw stream");
const char *link_tag[2] = {"i2s","raw"};
audio_pipeline_link(pipeline, &link_tag[0], 2);

audio_pipeline_register(pipeline_play, i2s_stream_writer, "i2s2");
audio_pipeline_register(pipeline_play, raw_write, "raw2");
ESP_LOGI(TAG, "[4.4] Link it together raw_stream->i2s stream-->[codec_chip]");
const char *link_tag2[2] = {"raw2","i2s2"};
audio_pipeline_link(pipeline_play, &link_tag2[0], 2);

start both of them.only pipeline_play is OK.

how to do it?

Can you show your full code, I think the issue maybe caused by during i2s read or write you have changed i2s settings such as call install or set clock API.
