Voice Assistant - No Sound

Hi,

Can I please have some help with my ESPHome voice assistant?

It’s detecting my wake word, but I can’t hear any response through the speaker. Although, the ESPHome logs suggest that it’s trying to output something.

I’ve tried swapping out the hardware to see if I have faulty boards. I’ve tried different configurations, including a shared I2S bus, and separate buses.
Text to speech works if I pick a different speaker and don’t use speech to text to trigger it.
My logs show that speech to text also works when talking to this satellite that won’t make sound.

Hardware


Guides and Resources I used

I thought this bug might be relevant, but others seem to have resolved the issue, while I have not.

I have same issue :confused:

Hi

do you use 5V pinout on ESP2-S3 for MAX98357 Vin ?
You have to solder the pad here

Thanks. I hear a loud crackling sound between powering the voice assistant and the first time it speaks. But that’s progress.

Although, in order for the voice assistant to hear me I have to muffle the speaker with my hands.
