HI Jon, I tried with cubieboard android kernel , then there is no issue with i2s soundcard, because it is fetching all parameter from fex file.
But only thing i am not able to invoke the external dac from machine driver and also i probed mclk,bclk which is working fine. Here i am attaching dmesg log once i play audio through i2s. *Log:* root@localhost:/# mplayer -ao alsa:device=hw=2.0 /Waka.mp4 Warning unknown option skin at line 101 MPlayer2 UNKNOWN (C) 2000-2011 MPlayer Team mplayer: could not connect to socket mplayer: No such file or directory Failed to open LIRC support.
