Unable to play opus(ogg) in littlefs

[maxzhangzhang]

Hello, All
I wrote a code to play the opus in littlefs, but it always says CodecOpus.h: 152 - Sample rate not supported: 44100. But I am sure that my audio sampling rate is 48000, so I don't know what the problem is.
`
#include <Arduino.h>
#include <AudioTools.h>
#include <LittleFS.h>
#include "AudioTools/AudioCodecs/CodecOpusOgg.h"

#define I2S_BCLK 16
#define I2S_LRC 17
#define I2S_DOUT 15

using namespace audio_tools;

I2SStream i2sOut;
OpusOggDecoder oggDecoder;
EncodedAudioStream decStream(&i2sOut, &oggDecoder);

void setup() {
Serial.begin(115200);
if (!LittleFS.begin()) {
Serial.println("LittleFS mount failed!");
while(1);
}
Serial.println("LittleFS ready");

auto config = i2sOut.defaultConfig(TX_MODE);
config.sample_rate = 48000;
config.bits_per_sample = 16;
config.channels = 1;
config.pin_bck = I2S_BCLK;
config.pin_ws = I2S_LRC;
config.pin_data = I2S_DOUT;
i2sOut.begin(config);

decStream.begin();

File file = LittleFS.open("/1.opus", "r");
if (!file) {
Serial.println("File open failed!");
return;
}

uint8_t buf[512];
size_t n;
while ((n = file.read(buf, sizeof(buf))) > 0) {
decStream.write(buf, n);
yield();
}
file.close();
Serial.println("end");
}

void loop() {}
`

Here is the usart print:
LittleFS ready [E] CodecOpus.h : 152 - Sample rate not supported: 44100 [E] CodecOpus.h : 152 - Sample rate not supported: 44100

please help me, THANKS

Please read the error message: you are setting up the decoder with 44100 which is the default ocnfiguration!
Provide a proper config when calling decStream.begin();

Thank for your replay, it's work. Thank you very much!!!
