Hi,

I setup my SMDK6410 as you note before. and, test again. I'm concerned
about my test process is right, because capture is still not working
on my test. Is there any problem with my test? or should I have to
write some more information about this test?

Details are following... :-

Board environment
 - CPU board setting
   - CFG6 - 1111 (all on)
 - Base board settings
   - CFG1 - 0000 (all off)
   - CFG2 - 1111 (all on)
   - CFG5 - connect pin 2 and 3

Kernel
 - repos ; git://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound-2.6.git
 - branch ; for-2.6.37
 - based on ; commit id - b6905d0b1652efddb96cefdb3c8552cac8d98ed2
 - config ; Add I2S driver and ALSA as a static into kernel(not a
module), remove AC97, and remove 'Secure Digital Host Controller
Interface support' on SDMMC, because of compile error.
