Symptom: Audio popping, crackling, or "DMA buffer underrun" errors in logs
Solution: Increase buffer duration
speaker:
- platform: i2s_audio
buffer_duration: 100ms # Increase from default 50ms
Symptom: Display works but touch has no effect
Solution: Check shared reset pin configuration
# Both display and touch share GPIO48 - MUST be inverted
display:
reset_pin:
number: GPIO48
inverted: true # CRITICAL
touchscreen:
reset_pin:
number: GPIO48
inverted: true # CRITICAL
Symptom: Display shows random pixels, flickers, or fails to render
Solution: Ensure PSRAM is enabled with 16-bit color
psram:
mode: octal
speed: 80MHz
display:
color_palette: NONE # Requires PSRAM for 16-bit color
Symptom: Click/pop sound at start or end of audio playback

bits_per_sample: 16bit
# Speaker: 48kHz (standard audio)
speaker:
sample_rate: 48000
bits_per_sample: 16bit
buffer_duration: 100ms
Symptom: "PSRAM not found" or display/audio failures
Solution: Explicit PSRAM configuration (2025.2+ requirement)
# BEFORE (auto-detection, no longer works)
# psram: true # DEPRECATED
# AFTER (explicit configuration)
psram:
mode: octal
speed: 80MHz
Symptom: Device reboots when voice assistant activates
Solution: Disable Bluetooth completely
# DO NOT include these components:
# bluetooth:
# esp32_ble:
# esp32_ble_tracker:
# ble_client:
# Voice assistant conflicts with Bluetooth on ESP32-S3
Symptom: Display freezes while OTA update is in progress
Solution: Enable execute_from_psram
