Wolfson DAC confirmed by Supercurio. Audio codec: Wolfson Micro WM1811 Audio Hubs | WM1811 | Wolfson Microelectronics 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.
