Hello, I was trying with a simple media player kit for a few evenings, can’t get it work as expected. I hope someone can help me.
My hardware setup:
ESP32-S3-DevkitC-1 N16R8 (not espressif original one)
PCM5102A DAC (small purple board)
LRCLK - GPIO15
DIN - GPIO16
BCLK - GPIO17
XSMT - GPIO10
I have tried different options so far:
- legacy I2S Audio Media Player with Arduino framework
- I2S Audio Speaker + Speaker Media Player with pipelines (full setup and simplest setup with only annoucement pipeline output to i2s audio speaker)
- I2S Audio Speaker + Speaker Source Media Player + Sendspin source
In each of the setup also tried in different sample rate (44100 or 48000), mode (stereo or mono), format (MP3 or FLAC), buffer duration (100ms to 1000ms).
What I can make success so far is with MP3 format playing from home assistant. It is quite ok without stuttering. My goal is to achieve playing media from Music Assistant, which is so far never succeed.
Here is my latest code I used:
