Things to sort out to further improve project and I need your help with that:
I2C code to display useful info and touch button controls
how to upload small mp3 files into flash memory, as an option to make ESP board to TTS sound on start and shutdown.
Have tried to add BLE functionality, however with arduino framework code overfill memory, so need to wait till developers will come with esf framework for i2s mediaplayers
Couldn’t get playlist figure out so mediaplayer plays from it, for the moment using default HA mediaplayer.
Just curious. Are you running the latest Esphome version? I have similar setup and it was working at one point. After some updates esphome, I am unable to play mp3. No audio coming out of the speaker and no error message. tts works only.
Are you trying to play from https addresses or http? Since some time ago https do not work, but you are able to use http links to play mp3.
Easiest way to check is, try to play internet radio, then if device works, play mp3. Try different mp3s, some mp3s do not work as firmware do not support some bitrates and Hz samples.
I am playing with http. These tracks were working before. I have never changed the mp3 file since. If I paste the url in a browser it works. Just odds how it stopped working one day. One day meaning almost half a year ago. I believe the internet radio is working. I tested before. Just mp3 files do not work. I even shorten the file name to number (1.mp3)
Updated code, added restart button and wifi signal level:

Some updates.
I tested a few radio station url. Some will play and some don’t. I get failed in log.
I have tried several other mp3 files and all will not play. However, mp3 files that are short ring tones or short messages will play.
This link from a user said his device stopped working with ESP32-audioI2S 2.1.0 v. Reverting back to esphome 2022.11.5 works.
I found this link from another user on steps on downgrading an add-on. Haven’t tried it and have questions before attempting to do so.
Esphome current version installed is 2023.6.5
I am using this DAC Module.
Check your mp3 files then. I’m using latest esphome, latest HA and same hardware.
Some radio stations stopped streaming online most likely thats why you can’t play those or streaming some other way than before, format might be different.
For mp3s - most of the mp3 files work just fine, others don’t, guess this is related to file names and format.
Another thing to pay attention is chip selection, Im using devboard listed in above article, tested S2 too, but it is too weak to play mp3s, radio etc as has only one core.
Device is very sensitive to signal strength, there for I have added code to display WiFi signal strength, position your device to keep it above 50%, 65-70% is perfect.
Sometimes device hangs-up for unknown reason, it still reacts to interface commands but refuses to play, guess that is my TV from which I normaly control HA, might be something else, not sure.
I have added soft reset to the interface - helps.
Esphome continuousely getting improvements, all required from end users - to go to github and submit issue or feature requests, someone from developers will either fix issue in next release or develop new feature.
For sure due to software being free that takes quite a time, people has their own businesses and HA developed on free time as a hobby.
I guess it boils down to the device that I am using or the mp3 files. I don’t know what chip I am using, but it is so strange it has been working after I finished setting it up. Never had any issues with playback when I used it. Then it stopped working one day. I didn’t change any settings. Just upgrade Ha and esphome whenever there was an update.
Thanks for the info.
I have lilygo ttgo v1 board where lora portion maybe defective. I may just tried to setup another player with it, but will need to purchase another dac since the one I have now has been soldered onto the board. I can’t find correct info if it is a single or dual core.
So I got it fixed. It was the mp3 files after all. I used Audacity to reformat some of the mp3 files and it works. This is a shame because I want to mainly use this setup to play my music collections. Having to upload the files to media folder is one thing, but I will need to reformat each files just so this device can play would be redundant.
Check you wifi signal, I had around 30% of mp3 files unplayable and some of MP3 files was playing with a lot of interruptions, some radio channels even played with poor quality. Today I have finally replaced my router with very good one from ASUS TUF, gaming one with WiFi6 support and you know what? Im able to play everything smooth, even those mp3 files which couldn’t be played, now play perfectly fine, no interruptions whatsoever.
So check your router, problem could be in it.
