XMEGA and audio possibility? | AVR Freaks
https://www.avrfreaks.net/forum/xmega-and-audio-possibility
The DAC in an Xmega is just 12 bit. To do 16bit PWM at 441.kHz would require a 289,0137,600 Hz clock speed (and that's mono). Of course you could add an external DAC (or two for stereo) to an Xmega and just feed it the samples at 44.1kHz. EDIT: nope CD is 16 bit while DVD/BluRay is 24 bit.

AVR1301: Using the XMEGA DAC
https://ww1.microchip.com/downloads/en/Appnotes/doc8033.pdf
The XMEGA™ DAC module is a high-performance Digital-to-Analog converter capable of conversion rates up to 1 M conversions per second with a resolution of 12 bits. High output driving capabilities, dual sample-and-hold outputs and optional routing of DAC output to on-board comparator or Analog-to-Digital converter (ADC)

• Set up the DAC in Single Conversion Mode using a driver • Play a pre-recorded sound track to the speaker 1. Locate the Atmel XMEGA-DAC folder. Open the xmega_dac.avrsln solution file and set Task 2 active by selecting it as StartUp project. The code in this task writes a piece of a sound track to the DAC. The sound track is
Making sinewaves with XMEGA DAC – M0AGX

The XMEGA is quite a leap from the “classic” AVRs. Some of the interesting features are the DAC and DMA. When combined, they can be used to generate all kinds of useful signals in the audio range. This example uses the DAC, DMA, timer and event system to generate 1200 Hz and 2200 Hz sinewaves.

I have an Xaduino board which is an XMEGA 128 chip with its own modified Arduino IDE (1.0.1) which can also be used like the original IDE. There is a library for the DAC which is basically the same as the XMEGAduino DAC library.
