+#32 bit ES9038
+
+For those who have a board with a 32bit DAC
+[DJ202](https://github.com/dj202) sent us a solution:
+
+
+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
+````c++
+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;
+````
