I recently started making a web radio player got esp32 and adafruit uda1334 board it works but the audio quality is awful(feels like highs non exist at all and lows kinda unnatural) compared to same speakers conected to pc and same station link playing on vlc.is that the uda1334 is garbage and need something like pcm5102 or i am doing something wrong?

code:

include "Arduino.h"

include "WiFi.h"

include "Audio.h"

define I2S_DOUT 26 // connect to DAC pin DIN

define I2S_BCLK 27 // connect to DAC pin BCK

define I2S_LRC 25 // connect to DAC pin LCK

Audio audio;

const char ssid = "SSID"; const char password = "password";

void setup() { Serial.begin(115200); WiFi.begin(ssid, password); while (WiFi.status() != WL_CONNECTED) delay(1500); audio.setPinout(I2S_BCLK, I2S_LRC, I2S_DOUT); audio.connecttohost("http://s1.knixx.fm/dein_webradio_64.aac"); }

void loop() { audio.loop(); }

void audio_info(const char *info){ Serial.print("info "); Serial.println(info); }

Did you connect a speaker directly to it? If yes: please note this board does not contain an amp.

Have been working in the past with uda1334 + TDA1308 as amp and this worked fine. Meanwhile I switched to MS6324 as it's easier to design.

For speakers I'd rather recommend MAX98357a (DAC + classD-amp).
