Firmware update
To get the best playback experience, we need to update XMOS firmware to Download the firmware from here. On your computer, plug in the ReSpeaker XMOS XVF3800 with XIAO ESP32S3 and run the in our guide:
The XVF3800 mic array needs a 12.288 MHz MCLK to work, but ESPHome (used in Home Assistant) can't generate it due to API limits. This firmware makes the XVF3800 act as the I2S master instead, so it can generate its own clocks without needing MCLK from the ESP32. Our firmware fixes this limitation, so the mic works properly with Home Assistant.
