Speaker volume control

[maxbraun]

Hi!

I'm using an ESP32-S3-Korvo-2 (V3.1) and I was wondering how to adjust the speaker volume.

I'm able to run the pipeline_http_mp3 example (https://github.com/espressif/esp-adf/tr ... e_http_mp3) just fine. How would I adjust it to increase the volume?

I tried i2s_alc_volume_set(i2s_stream_writer, ...), but that call gives an error. I'm also not sure what values are valid.

Thanks!
Max

audio_hal_set_volume(board_handle->audio_hal, 100);

When making i2s_stream_writer initialization, configure the i2s_cfg.use_alc=true.

Code: Select all

ESP_LOGI(TAG, "[2.2] Create i2s stream to write data to codec chip");
    int player_volume=0;
    i2s_stream_cfg_t i2s_cfg = I2S_STREAM_CFG_DEFAULT();
    i2s_cfg.use_alc = true;
    i2s_cfg.volume = player_volume;
    i2s_cfg.type = AUDIO_STREAM_WRITER;
    i2s_stream_writer = i2s_stream_init(&i2s_cfg);
