...

I have not had time to make some changes suggested by the maintainers as I have been too busy. I will start that again soon Brian

The follow is cs42l52 machine code for Samsung S5PC100 and system log. I used aplay tool to test the system with wav file, but don't hear any voice from the speakers. where is the BUG of this code ? Please help me,and thanks!

the cs42l52 codec driver is from Brian. I port this codec driver to Samsung S5PC100 2.6.29 kernel.

A). cs42l52 machine code for Samsung S5PC100.
