Hi all,

I wanted to share my latest project: a DIY network media player built with an ESP32-S3-DevkitC-1 (N16R8) and a PCM5102A DAC.
This is a very simple build which many people have done. But I met some troubles when building it, I hope my notes could help someone who has same issue.

The goal was to create a stabel player that could handle high-bitrate streams within the Music Assistant.

Key Technical Features:

  • Buffer Optimization: Utilizes media buffers and optimized sdkconfig to leverage 8-line Octal PSRAM.
  • Dual-Pipeline Support: Handles both music from MA (via Sendspin) and HA announcements simultaneously.
  • Verified Hardware: Includes 3D printable enclosures and a full soldering guide.
  • Jack Detection: Uses the pin of Jack to detect whether jack in plugged and switch between deep sleep mode.
  • ESPHome Based: Easy to customize and integrate into your existing dashboard.

I’ve published the full documentation, including a deep dive into my debugging process and various coding strategies (Standard vs. Sendspin vs. Hybrid).

Thanks to community and especially to Arh for their great help to me!

thanks for help, I have used PCM5102 board like yours and didn’t have any sound but with your instructions now it works!
Only thing is that I have a super mini S3 board which have 2Mb PSRAM but it works ok with FLAC.

Found a BT emitter, now I am thinking of doing a V2 of this, adding this BT emitter so that can also connect to BT speaker or earphone.
