Hi, I have ported code "Enable sound on mx31_3ds" from Philippe Rétornaz to MX27 3DS platform on master branch of linux-next (tag next-20120806). I also applied patch "dma: imx-dma: Fix kernel crash due to missing clock conversion" of Fabio Estevam which is not yet merged in linux-next. Thanks to them, everything is working good on MX27 3DS platform except that sound is played too fast. Which parameter must be adjusted to have sound playing at normal speed ? In mc13783 codec driver, imx_add_imx_ssi(), clock configuration in mach-mx27_3ds file ?
Thanks for your help.

I have added audio support for mx27pdk: https://patchwork.kernel.org/patch/1152951/
,and in my tests the audio was played at the correct rate.
Can you please have a try?
What is the sampling rate of your file?
