I'm stumped. Strange issue with ESP8266Audio
Having an issue here using the ESP8266 Audio library (found here).
-
Playing a local sound via i2s and speaker component
The Arduino sketch that works for me reads the data out of PROGMEM. When I use that same raw data in ESPhome, it crashes my ESP too. Would there be a way to play from PROGMEM in ESPhome too? Other ways in the library are a function or streaming, but that doesn't fit my use case unfortunately.

Just Released My ESP32-S3 Audio Dev Board
If you're getting started, the ESP8266Audio library makes it easy to play audio with the Arduino toolchain. For more advanced use cases, Espressif's own ESP-ADF has a lot of useful features and examples.

Confusing Pin Default
Not sure where you got that. According to the ESP8266Audio documentation, the default GPIOs are 2, 15, and 3. You're trying to change 15 to 13.

When I successfully make ESP8266Audio working~
ESP8266Audio is really fun and easy to use
- Really? I have been looking for an example of playing mp3 using PAM8302 esp32, and could not find anything out there. anyone can help me?
-
need some help choosing which pi would be best suited for retrofitting inside a nokia 3310
The ESP32 might suffice for that then, depending on what you consider to be basic applications. It certainly has wifi and bluetooth functionality and you can do audio with an extra chip or an interesting workaround. The ESP32-A1S module even has the necessary chip integrated but you'll likely need to roll a custom PCB for it.

Sound Module Suggestion
This library documentation has some more information on this... https://github.com/schreibfaul1/ESP32-audioI2S/wiki
- Trying to figure out how to play an audio file using a ESP32, this is our build, code in the comments. Any assistance?

Butting my head against extracting ID3 data and putting it into a JSON/Updating a Web Page
I'm using Audio.h, and have reverse engineered the library: https://github.com/schreibfaul1/ESP32-audioI2S/blob/master/src/Audio.cpp

Combine 2 analog signals = mixing?
Are you sure? This project seems to think otherwise, although if you want analog it might be a fun experiment to make it use the ESP32's DAC rather than the I2S peripheral.
-
Is it possible to stream audio from a web server to an ESP32?
I think the best way is to use a I2S amplifier, and a library like this: https://github.com/schreibfaul1/ESP32-audioI2S

HELP! Cannot get I2S output on Adafruit esp32 feather V2!
I use that same DAC for this project : https://github.com/marchingband/campusradioradio/blob/main/campusradioradio.ino which uses this Arduino library https://github.com/schreibfaul1/ESP32-audioI2S

PSRAM alternatives?
I need to add more memory to my Lolin32 Webradio to avoid the constant dropouts that some stations have given. I use the ESP32-audioI2S library. Here in Brazil, access to components is extremely difficult, and we often resort to expensive imports via Aliexpress or eBay. The modules or memory chips that we have on the market are usually of the I2C flash type, like this one or this one. On Aliexpress, the only PSRAM I found was the 23LC1024 chip (128kB - $5.04). But I see chips 23K256 (32kB SPI serial SRAM - $1.38), 24C1024 (128kB I2C EEPROM - $2.30) and 25LC1024 (128kB SPI EEPROM - $1.84) available. Can I use these cheaper options?
