Re: [alsa-devel] About CS42L52---Where to find CS42L52 ASoC driver

2 Nov 2010


      Hello,guys!
2010/10/13 James Liu telecom888@gmail.com:

2010/10/13 Austin, Brian Brian.Austin@cirrus.com
...
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.
