Does mp3 play works without external DAC on ESP32?

[Mir1001]

I got board with amplifier ICs FM8002A and ESP32. I am able to play mp3, but sound is heavy distorted (Wav and mp3 file). If I play artificially generated sound it almost works. I have tried different combinations:

Best I got listen here

AudioOutputI2S *outs(int o) //o - selected option
{
    switch (o)
    {
    case 0: // distorted almost works
        return new AudioOutputI2SNoDAC();
    case 1:
        return new AudioOutputI2S(); // loud and distorted
    case 2:                          // sample rate is too small, the mclk division exceed the maximum value 255
        return new AudioOutputI2S(0, AudioOutputI2S::INTERNAL_DAC);
    case 3: // i2s_calculate_pdm_tx_clock(720): sample rate is too small, the mclk division exceed the maximum value 255
        return new AudioOutputI2S(0, AudioOutputI2S::INTERNAL_PDM, 8, AudioOutputI2S::APLL_ENABLE);
    case 4: // loud and distorted
        return new AudioOutputI2S(0, AudioOutputI2S::EXTERNAL_I2S, 8, AudioOutputI2S::APLL_ENABLE);
    case 5:  // loud and distorted
        return new AudioOutputI2S(0, AudioOutputI2S::EXTERNAL_I2S, 8, AudioOutputI2S::APLL_DISABLE);
    default:
        return nullptr; // Handle unexpected values of 'o'
    }
};

Can someone give me any suggestion at lest confirm that it should work or that you had same problems ;(.

Thanks
