Moin zusammen,
ich hab die Platine von @biologist und einen Lolin D32 Pro. Nun habe ich eine MP3-Datei auf die SD-Karte geladen und folgende Probleme:
- Der Ton hat ein krasses Rauschen, hab auch bereits einen anderen Lautsprecher getestet, leider mit dem gleichen Ergebnis. Plus/Minus sind richtig herum, und auch ein Vertauschen hat keine Besserung gebracht.
Anbei kurzes Video:

Folgende Dinge hab ich jeweils angepasst gehabt:
//########################## MODULES #################################
#define PORT_EXPANDER_ENABLE // When enabled, buttons can be connected via port-expander PCA9555 (https://forum.espuino.de/t/einsatz-des-port-expanders-pca9555/306)
//#define I2S_COMM_FMT_LSB_ENABLE // Enables FMT instead of MSB for I2S-communication-format. Used e.g. by PT2811. Don't enable for MAX98357a, AC101 or PCM5102A)
#define MDNS_ENABLE // When enabled, you don't have to handle with ESPuino's IP-address. If hostname is set to "ESPuino", you can reach it via ESPuino.local
//#define MQTT_ENABLE // Make sure to configure mqtt-server and (optionally) username+pwd
//#define FTP_ENABLE // Enables FTP-server; DON'T FORGET TO ACTIVATE AFTER BOOT BY PRESSING PAUSE + NEXT-BUTTONS (IN PARALLEL)!
#define NEOPIXEL_ENABLE // Don't forget configuration of NUM_LEDS if enabled
//#define NEOPIXEL_REVERSE_ROTATION // Some Neopixels are adressed/soldered counter-clockwise. This can be configured here.
#define LANGUAGE DE // DE = deutsch; EN = english
//#define STATIC_IP_ENABLE // Enables static IP-configuration (change static ip-section accordingly)
#define HEADPHONE_ADJUST_ENABLE // Used to adjust (lower) volume for optional headphone-pcb (refer maxVolumeSpeaker / maxVolumeHeadphone) and to enable stereo (if PLAY_MONO_SPEAKER is set)
#define PLAY_MONO_SPEAKER // If only one speaker is used enabling mono should make sense. Please note: headphones is always stereo (if HEADPHONE_ADJUST_ENABLE is active)
#define SHUTDOWN_IF_SD_BOOT_FAILS // Will put ESP to deepsleep if boot fails due to SD. Really recommend this if there's in battery-mode no other way to restart ESP! Interval adjustable via deepsleepTimeAfterBootFails.
#define MEASURE_BATTERY_VOLTAGE // Enables battery-measurement via GPIO (ADC) and voltage-divider
//#define MEASURE_BATTERY_MAX17055 // Enables battery-measurement via external fuel gauge (MAX17055)
//#define SHUTDOWN_ON_BAT_CRITICAL // Whether to turn off on critical battery-level (only used if MEASURE_BATTERY_XXX is active)
//#define PLAY_LAST_RFID_AFTER_REBOOT // When restarting ESPuino, the last RFID that was active before, is recalled and played
//#define USE_LAST_VOLUME_AFTER_REBOOT // Remembers the volume used at last shutdown after reboot
#define USEROTARY_ENABLE // If rotary-encoder is used (don't forget to review WAKEUP_BUTTON if you disable this feature!)
#define BLUETOOTH_ENABLE // If enabled and bluetooth-mode is active, you can stream to your ESPuino via bluetooth (a2dp-sink).
//#define IR_CONTROL_ENABLE // Enables remote control (https://forum.espuino.de/t/neues-feature-fernsteuerung-per-infrarot-fernbedienung/265)
#define CACHED_PLAYLIST_ENABLE // Enables playlist-caching (infos: https://forum.espuino.de/t/neues-feature-cached-playlist/515)
//#define PAUSE_WHEN_RFID_REMOVED // Playback starts when card is applied and pauses automatically, when card is removed (https://forum.espuino.de/t/neues-feature-pausieren-wenn-rfid-karte-entfernt-wurde/541)
//#define DONT_ACCEPT_SAME_RFID_TWICE // RFID-reader doesn't accept the same RFID-tag twice in a row (unless it's a modification-card or RFID-tag is unknown in NVS). Flag will be ignored silently if PAUSE_WHEN_RFID_REMOVED is active. (https://forum.espuino.de/t/neues-feature-dont-accept-same-rfid-twice/1247)
//#define SAVE_PLAYPOS_BEFORE_SHUTDOWN // When playback is active and mode audiobook was selected, last play-position is saved automatically when shutdown is initiated
//#define SAVE_PLAYPOS_WHEN_RFID_CHANGE // When playback is active and mode audiobook was selected, last play-position is saved automatically for old playlist when new RFID-tag is applied
//################## select RFID reader ##############################
//#define RFID_READER_TYPE_MFRC522_SPI // use MFRC522 via SPI
//#define RFID_READER_TYPE_MFRC522_I2C // use MFRC522 via I2C
#define RFID_READER_TYPE_PN5180 // use PN5180 via SPI
// Power-control
#define POWER 115 // GPIO used to drive transistor-circuit, that switches off peripheral devices while ESP32-deepsleep
#ifdef POWER
#define INVERT_POWER // If enabled, use inverted logic for POWER circuit, that means peripherals are turned off by writing HIGH
#endif
Ich hatte direkt zwei Lolin D32 Pro bestellt und mit dem zweiten genau das gleiche Verhalten. Ich frag mich jetzt nur an was es noch liegen könnte, hätte jemand irgendeine Idee was ich noch versuchen könnte?
