Wolfson DAC confirmed by Supercurio
Lots more detail about the S3, including exclusive stuff not covered anywhere else here (exFAT support, expanded USB OTG function, details of new bluetooth stack etc etc).
Audio codec:
Wolfson Micro WM1811 http://www.wolfsonmicro.com/products/audio_hubs/WM1811/
100dB SNR Class W Heapdhone amp output, ReTune DSP, 3x digital interface.
Like WM8994 in Galaxy S / Nexus S, except:
1x stereo DAC instead of 2x.
2x 2W Speaker amp instead of 2x 1W
Smaller and probably cheaper, same sound quality expected.
Audio driver configuration & policy implementation based on TinyUCM (/etc/tinyucm.conf)
Probable subset of TinyHAL implementing codec configuration in config files instead of having everything hardcoded in ROM or kernel driver at compile time.
Native sampling rate: 44100 Hz. It means music played will be sent as-is to the DAC instead of being processed by a software up-sampling routine as it is on Galaxy Nexus or other devices with codecs accepting only 48000 Hz.
AWESOME.
