Here is the code to init pwm stream:

pwm_stream_cfg_t pwm_cfg = PWM_STREAM_CFG_DEFAULT(); pwm_cfg.pwm_config.tg_num = TIMER_GROUP_1; pwm_cfg.pwm_config.timer_num = TIMER_1; pwm_cfg.pwm_config.gpio_num_left = GPIO_NUM_47; pwm_cfg.pwm_config.gpio_num_right = GPIO_NUM_48; pwm_stream_writer = pwm_stream_init(&pwm_cfg); if(pwm_stream_writer==NULL) { ESP_LOGE(TAG, "Failed to init pwm stream."); }else{ esp_audio_output_stream_add(handle, pwm_stream_writer); }

but it reports errors below: (means no output stream). my app use both timer and ledc pwm, but I have tried to avoid conflict. please help me debug this issue.

add #pwm to your play uri and have a try file://mp3//power_on.mp3#pwm

Tried, but got similar error:

I see somecode in library only allow "raw" and "file" as output in hardcode. To workaround to fix this issue you can force set stream name as iis. We will fix the lib issue soon.

    esp_audio_output_stream_add(player, pwm_stream);
    audio_element_set_tag(pwm_stream, "OUT_iis");

Thanks. This makes the error message disapeared, but it does not output any sound at all. And it seems the pipeline for the first mp3 will never stop. So, all following mp3 play will generate error message like below:

W (54602) ESP_AUDIO_CTRL: Pipeline is already running. Please stop it first.
