32 bit ES9038

[DJ202]

There are some great sounding and cheap 32 bit decoders available like boards with the ES9038Q2M that don't work because the library outputs 16 bits data.
You only need to change 3 lines lines of code to change it to 32bit:

Audio.cpp

in Audio::Audio

m_i2s_std_cfg.slot_cfg = I2S_STD_PHILIPS_SLOT_DEFAULT_CONFIG(I2S_DATA_BIT_WIDTH_32BIT, I2S_SLOT_MODE_STEREO);

in Audio::resampleTo48kStereo:

m_samplesBuff48K[outputIndex * 2] = clipToInt16(outLeft);
m_samplesBuff48K[outputIndex * 2 + 1] = 0x00;
m_samplesBuff48K[outputIndex * 2 + 2] = clipToInt16(outRight);
m_samplesBuff48K[outputIndex * 2 + 3] = 0x00;

Thanks for your contribution. For all others who also want to use such a DAC, I have added your solution to the examples.
