The ESP32S3 will restart if online music is played

ESPHome
1

I created two buttons for testing.
If button A3 is pressed, playback is normal, and the ESP32S3 will not restart.

a3 media_url: ‘http://192.168.1.1:8080/static/music.mp3’

If you press button A4, the ESP32S3 will restart.
a4 media_url: ‘http://m10.music.126.net/20251106145338/61c9045ca5ef9d5d9177f15d5c162fd4/ymusic/48d9/4013/934e/cb8eb10c6141e33ab5e45033c10c10f2.mp3’
(The music link worked when I tested it, but it’s probably inaccessible now.)

Does anyone know what happened?

Just a few remarks
Do you use an ESP32-S3 WROOM N16R8 ?
According the psram: section you do.

Also you use a lot of buffers. That takes up a lot of RAM.
Remove a few of them since not all are needed and try to make the remaining one) smaller like 500ms the see if that works

I have only a buffer at speaker:

speaker:
  - platform: i2s_audio
    id: speaker_id
    i2s_audio_id: i2s_out
    dac_type: external
    i2s_dout_pin:   
      number: GPIO8 #DIN Pin of the MAX98357A Audio Amplifier
    sample_rate: 48000
    buffer_duration: 600ms #90ms

  - platform: mixer
    id: mixer_speaker_id
    output_speaker: speaker_id
    source_speakers:
      - id: announcement_spk_mixer_input
      - id: media_spk_mixer_input

  - platform: resampler
    id: media_spk_resampling_input
    output_speaker: media_spk_mixer_input
  - platform: resampler
    id: announcement_spk_resampling_input
    output_speaker: announcement_spk_mixer_input


media_player:
  - platform: speaker
    name: None
    id: speaker_media_player_id
    media_pipeline:
        speaker: media_spk_resampling_input
        num_channels: 1
    announcement_pipeline:
        speaker: announcement_spk_resampling_input
        num_channels: 1

To get that extra bit of memory you need these switches

    sdkconfig_options:
      CONFIG_ESP32S3_DATA_CACHE_64KB: "y"
      CONFIG_ESP32S3_DATA_CACHE_LINE_64B: "y"
      CONFIG_ESP32S3_INSTRUCTION_CACHE_32KB: "y"

      CONFIG_SPIRAM_RODATA: "y"
      CONFIG_SPIRAM_FETCH_INSTRUCTIONS: "y"

      CONFIG_BT_ALLOCATION_FROM_SPIRAM_FIRST: "y"
      CONFIG_BT_BLE_DYNAMIC_ENV_MEMORY: "y"

      CONFIG_MBEDTLS_EXTERNAL_MEM_ALLOC: "y"
      CONFIG_MBEDTLS_SSL_PROTO_TLS1_3: "y"

This works much better, but it still restarts.

Calling action: media_player.play_media in home-assistant makes it run very stably.

My initial idea was to allow ESPHome to play music even without home-assistant.

It seems this idea is a bit too much of a burden for ESP32.

Have you read the docs for tips? The bit about WiFi may be worth reading.

I use esps for media a lot without issues.

Are you sending music to ESPHOME using Home Assistant? This method works stably in my code. I’m trying to push the playback address of a music server directly to ESPHOME for playback, so it doesn’t go through Home Assistant, but I didn’t expect the results to be so poor.

Well, my whole house audio system uses only one esp32-s3 in esphome and it stream internet radio the whole day so it is possible.
