I know this is likely to get buried, but just for everyone that is still struggling with this process here is my working config file for an INMP441 microphone and a PCM5102 DAC as the sound output. This device functions with wakeword detection and as a media player from HA. I spent a week bashing my head against this before I found out that my issue was actually network related. The firewall on my HA server (running HA container) was not allowing the UDP connection from the ESP32 devices. I have not been able to narrow down which port is used for the mic streaming so right now I just all all UDP from the IP address of my ESP32 allowed in ufw.
Wiring as Follows:
| ESP32 Pin Label | INMP441 Pin Label | PCM5102 Pin Label |
|---|---|---|
| 5V | VIN | |
| 3.3V | VDD, L/R | |
| GND | GND | GND |
| GPIO33 | SCK | BCK |
| GPIO25 | WS | LCK |
| GPIO22 | DIN | |
| GPIO32 | SD |
I did need to solder connections to the PCM5102 in order to get reliable audio. With jumper wires on a breadboard, the audio would cut out regularly and the whole set up needed to be held "just right" to have any audio at all.

@ibrummel , where are speaker and/or media_player in the Yaml config ?
@Krull56 My apologies. I must have copy pasted out of the wrong file. I have a lot of things open. I have updated my original post with the correct code as well as adding some notes on wiring.
I am trying to get this to work with a ESP32 C3 Super Mini. Has anyone tried that before?
Sometimes I boot the esp and then suddenly it is giving a whole bunch of log lines within the same second, the cycle over and over. Code without light works fine.

Just over and over within the same second. Sometimes restarting it works, sometimes it starts working on its own. How to fix?
I used the original code.
Sometimes it wont even start the code after unplug/replug. Then the speaker starts crackling loudly, sometimes not. Very buggy.
@BlackCube4 I read somewhere that won't work. Did you make it work anyway?
@Xornop That logging loop is what you would expect to see. When a wake word is detected the logs will start showing the intent flow.
Unfortunately there are issues with ESP home and i2s/voice assist. After getting everything working on the hardware side Im able to trigger one or two commands before the assist pipe line just stops running.

The device will just keeping pinging until it is rebooted. Once rebooted I can run 1-2 commands and then i run into the same issue. Looking around on the forms im seeing other have the same issue.
@BlackCube4 I read somewhere that won't work. Did you make it work anyway?
I got it to work fine~ish
@Xornop That logging loop is what you would expect to see. When a wake word is detected the logs will start showing the intent flow.
Not within the same second, it completely freezes up the esp.
...I found out that my issue was actually network related. The firewall on my HA server (running HA container) was not allowing the UDP connection from the ESP32 devices. I have not been able to narrow down which port is used for the mic streaming so right now I just all all UDP from the IP address of my ESP32 allowed in ufw.
@ibrummel Thank you!!! I've been banging my head against the desk for an hour trying to figure this out. I would have never in a million years thought of a firewall issue - I'm so used to ESPHome devices working without messing with the firewall and never would have considered that this uses UDP.
Has anyone managed the fix the crackling noise? As soon as i switch the wakeword option on. the speaker starts to make this crackling noise. changing the bitrate didn´t help. i tried another esp32 board/mic/amp, but the problem stays the same.

Change the dout pin on the speaker. I have mine on GPIO12.

Anybody know how to limit the max volume with the Max98357?
Ive built 3 of these now:
https://youtube.com/shorts/-tBJXZdqqRw?si=Tfem5Rv8X2GZ0gWe
A couple things I have learned.
Be careful with the Microphone, the INMP441. If you get it too hot, you'll kill it. If you have a long delay between the command and the action, its more than likely the microphone.
I seem to have better luck building and wiring the voice assistant before loading the firmware onto it. So, get the basic firmware loaded, then build and wire the voice assistant. After that, load the final firmware.
If you are just seeing the basic firmware in the ESP32 interface, select "Clean Build Files" in ESP home by clicking the 3 dots, and then upload the firmware.
Spamming too many commands too quickly will freeze the pipeline. In normal use, you wont be sending 10 commands a minute, so slow down in testing.

The 3 I have built are running well and reliably. They dont like too much background noise, but some tweeking may help that. I have an automation that will mute my TV on wake word detection to help.
Im also running Home Assistant on a bare metal machine with an I7 and 16gb RAM
Has anyone managed the fix the crackling noise? As soon as i switch the wakeword option on. the speaker starts to make this crackling noise. changing the bitrate didn´t help. i tried another esp32 board/mic/amp, but the problem stays the same.
Change the dout pin on the speaker. I have mine on GPIO12.

Thank you that did the trick and also thank you for the post after that (-: !!!
@rich33584
That config seems to be working for me. Im still hitting some issues with TTS getting cut short or the wake work getting picked up by STT. But all in all its actually working better.
Heres a wire mapping for anyone who is going to try it out:
Mapping:
| ESP32 (WROOM-32) | MAX98357A (Speaker) | I2S Microphone |
|---|---|---|
| GPIO33 | DIN | - |
| GPIO12 | LRCLK | - |
| GPIO13 | BCLK | - |
| GPIO34 | - | SD |
| GPIO25 | - | WS |
| GPIO26 | - | SCK |
| 3.3V | VDD | VDD |
| GND | GND | GND |
@rich33584 That config seems to be working for me. Im still hitting some issues with TTS getting cut short or the wake work getting picked up by STT. But all in all its actually working better.
I seem to have spells of hours that it works perfectly, and then hours where the TTS is broken and crappy.
Not sure if its a wifi issue or if the ESP32 is just barely adequate to run these. I ordered som "Better" esp32 modules. Ill report back on them.
Have you seen this?
https://beta.esphome.io/components/micro_wake_word.html
Has anyone luck with an ESP32-S3? The device seems to be more capable to manage the workload
In case someone needs a working config without crackling speakers in correct formating.

I keep getting this error what do i do?
my setup has a screeching sound instead of a crackle when playing back a response. using the setup posted above but using different gpio pins.
Any ideas?
I have discovered, that many of the problem mentioned above is due to interference noise. I had a lot of crackling noise with 10 cm wires on my test setup. So I had to go study on the net.
I2S is ment to be used between components on a PCB. It is without error protocol, so any errors will result in some kind of static noise. The solution is to keep the I2S connection as short as possible. There is no room for the pins on the ESP32 in my box. So I cut those off. Though I left the plastic part of the pin-row. I clammed the MAX98357A board on the backside of the ESP32 PCB, so I only needed 5 mm of wire. I placed the INMP441 on the side-edge of the ESP32 so they form a T (because that works with the box i use). And now it works without any noise.
I don't know how long the wires can be without shielding. But if you need to have even longer wires, they must be individually shielded (only the I2S wires). Shields should be connected to ground on the ESP32 (so only connected in one end). I have no idea how long they then can be. But not especially long. Maybe 20-30 cm?

I was doing some serious google'ing and ran across this Github repo: https://github.com/gnumpi/esphome_audio
Using a lot of what was put in this thread and the work that gnumpi has done on media-player for esp-idf, I have put together this config running on an esp-wroom-32. Still testing (and I think that I'm going to need a S3 board to make this reliable) but I did get it to work last night with a mic and speaker (4Ohm, 3W) with great sound.
Next I am going to add a 16bit led ring and see if I can get even better success on an S3 board.

Hi imonlinux, many thanks for sharing your config. Good to know, that the media_player component can be configured with the idf framework also. I have tried this with a wroom32 board using very short wires, but it makes noise almost suppressing the speech.
Earlier I had some success with S3 board, but using the arduino framework. The output sound was clear, but the media_player function was not stable. And I could not figure out, how to get the mic work with the assist pipeline. Physicly the mic was OK (I tested it with a separate Arduino test program on the same board), but Home Assistant did not recognize it.
I plan to try your config on the S3 board, if possible, to see, how it performs...
Hey Battman2013, I have been hacking away at a config for the ESP32 S3 N16R8. I purchased some from Amz and the following config is working pretty well. I was troubleshooting the MAX98357A only working on the 3.3v pin when I ran across this thread:
https://forum.arduino.cc/t/chinese-esp32-s3-5v-pin-warning/1192758
Once I bridged the IN-OUT pads, the 5v pin started making 5v. Also, I'm only using the onboard LED for the light. Saving my 16bit rings for boards that don't have them, like the XIAO ESP32 S3. Still troubleshooting the MIC on that one.
Next up is local wake word.

Hey indevor. Thanks for catching that mistake.
I have updated my previous post with this correction. Explains why I was fighting with my microphone on the XIAO ESP32 S3 board.
CONFIG_TCP_SND_BUF_DEFAULT: "65535"
CONFIG_TCP_WND_DEFAULT: "512000"
CONFIG_TCP_RECVMBOX_SIZE: "512"
could you explain how this works?
or a link to a primary source?
I had to redo my code again and made a slight change due to using a strapping pin in the first esp32, which messed around with my how the VA worked, after loosing my original config due to server issues, through trial and error again i got it working well with no crackling, the only thing different to your config and mine is that you are using the media player and i am using speaker and of course lights etc, my config below FYI, also using the latest HA.
