I have an ESP32-WROOM-32 set up like this (wiring image at the bottom); only relevant parts, I cropped out wifi etc.
esp32:
board: esp32dev
framework:
type: arduino
i2s_audio:
id: testy
i2s_lrclk_pin: 9 #GPIO25
i2s_bclk_pin: 10 #GPIO26
media_player:
- platform: i2s_audio
name: ESPHome I2S Media Player
dac_type: external
i2s_audio_id: testy
i2s_dout_pin: 12 #GPIO14
mode: mono
### ---> I've found this part when searching for i2s audio issues:
on_pause:
- media_player.stop
This is the output I receive when playing an audio file; I specifically chose a very short (<2sec) WAVE audio file hosted on my HASS server. Other media players in my network play this without issues.

It seems like the board crashes / reboots when I try to play media. Can you please tell me what I did wrong and/or what to do in order to fix this? Thank you in advance for your help
When I try to play any media, the ESP32 reboots, even without the MAX98357 module connected. I didn’t have any problems with the internal DAC. Switched to external due to poor sound quality. I did some tests with different pins but no difference.
Has anyone managed to use esp32 with external i2s DAC?

Has anybody else encountered this issue and perhaps found a solution? It is kinda disappointing having bought this supported hardware and just realizing it doesn’t actually work when trying to build a project.
