Moving the caps looks easy enough do you need to also update the register too or is that in the new patch ?
The external component I posted above now has the setup changes recommended by @Night.Dav3 up through this post. So the register changes to get mics working and now enable automatic gain correction for improved voice detection.
It compiles fine for me but I haven’t tested as I messed up while moving one of the capacitors.
You have to modify the caps and use the new code to have it working.
@mulcmu : voice assistant uses the right mic in mono mode, so if you do the mod on the right mic only it might work…

I can’t find anywhere what the size of the JST connectors are for connecting the speakers.
Can anyone provide information?
Thank you

Thanks for your hard work and assi6 have it working now after moving the caps and using the new code
I have the same v2.2 A247 board.
I will move the capacitors to the correct positions.
I would just like to know what is the distance from the microphone so that the assist recognizes the voice command correctly?
I had the beard at arms length on the desk and it could still function
if got everything working but i wanted to connect a screen to the i2c buss what io pins are these where on the board has to be scl sda ?
Nevermind if got it working but the voice recognition or mic is not really god. Is there a possibility to add a external i2s mic ?
The esp32 v 2.2 A149 board also had misplaced capacitors. After the fix, voice control works.
I must be doing something wrong. Pressing KEY6 and saying the command to turn the light on and off works, but no voice from the player.
Player esp32-A1s tested via NabuCasa (play voice) and it works.
What else do I need to set in HA for the esp32-A1s player to work (voice response).

I would like to use an external Mic with mine as well. Did you ever get this working?
Has anyone managed to get the wake word assist to work on this board?
In my house she appreciates the unfinished projects. They keep me busy.

Fortunatelly, the tts response will be supported in the upcoming release(s), since now only mp3 tts (behind http) is the only supported now. Piper returns wav/raw by default:
Unfortunatelly, https streams (such as tts) are still unsupported:
Hello , I got the board to work (STT and TTS) with Home-Assistant but like @pepe59 asked , does anybody knows how to make OpenWakeWord work for this board?
Hi, first you have to know that there are at least 7 versions of the A1S Audio Kit. The major difference is a version with AC101 codec and another one with ES8388 but as we can read in this topic there’s also some other differences (like the caps on the wrong places sometimes).
About these versions :
- Lots of info on the squeezelite-esp32 github repo
- This video shows identical cards (same version number!) but with a different DAC: the old ones have an AC101 DAC (and a pigtail on the ESP) and the new ones an ES8388 DAC.
- Phil Schatzmann’s article on the subject
- 7 iterations of the boards cited here with their pins
- Sometimes the microphone capacitors are soldered in the wrong place (in this topic)
On my side, I have an old A1S board with AC101 codec. Fortunately I’ve found this issue & this repo. It works well (Thanks Sehraf !), I took inspiration from Muse Luxe configuration to create my own ESP configuration forht ethe A1S with AC101 codec that I share with you :

It’s not perfect but it allows to start to play with Voice Assistant with this great board.
Some issues :
- At boot it often enter in a crazy loop on wake word initialization (like this on this topic or this one). Just disable “Use Wake Word” toggle and enable it again to stop this loop. It seems to be related to the “voice_assistant” automations configured. A workaround could be to start Voice Assistant only after few seconds (as it seems related to the I2S microphone not initialized or something like that).
- The jack is working however I didn’t found how to detect the jack to disable the amp if necessary (pin 39 doesn’t seem to work).
- GPIO19 is muxed so I didn’t found how to use the key3 and the LED D5 simultaneously (ESPHOME refuse to use the same GPIO two times)
- The media player is working but require to disable “Use Wake Word” first. May be we could find a trick in HA to disable it automatically when something is played.
- Volume is reset to 100% after each restart.
So it can be improved a lot, for example the keys could be mapped for Media Player. I’m sure that the issues could be fixed by someone with a great debugging level on ESPHome
I hope that it will help some of you, once configured the result is not bad at all, even if only one microphone is used, the wake word detection is not bad at all even at several meters or by whispering. The media player is working fine, the speakers and the audio jack output too. Even if Voice Assist is far from perfect, at least my board has a use now

Thanks for sharing!
After switching the caps my mic’s are working… anyone figured out how to make the jack working or added BT support?
