Planning to buy a DUE, stereo WAV playing?

If you look at DAC.cpp file in tha audio Library:

arduino-libraries/Audio/blob/master/src/DAC.cpp

#include <DAC.h>

void DACClass::begin(uint32_t period) {
	// Enable clock for DAC
	pmc_enable_periph_clk(dacId);

	dacc_reset(dac);

	// Set transfer mode to double word
	dacc_set_transfer_mode(dac, 1);

This file has been truncated. show original

You can see, from line 42:

// Enable output channels
  dacc_enable_channel(dac, 0);
  dacc_enable_channel(dac, 1);

Plus the DAC peripheral is programed to output on both DACs in this Library.

Note 1: Never connect your DAC (either DAC0 or DAC1) directly to a speaker or you will burn your DAC.

Note 2: I don't know what sound quality you can get with this Library, search on the internet feed back experiences with it on a DUE.
