Can you please have a try? What is the sampling rate of your file? Regards, Fabio Estevam
Hi Fabio, Sorry, I have missed your patch in my email archive. I didn't search the right keywords. I applied your [patch 1/2] (2/2 is already merged) but I have same effect. I use aplay with file k3b_error1.wav (Unsigned 8 bit, Rate 8000 Hz, Mono) and alsa/Front_Left.wav (Signed 16 bit Little Endian, Rate 48000 Hz, Mono). Two sounds are played too fast. It is maybe a bad configuration of Alsa (but this is working with kernel 2.6.22 from Freescale). Thanks. Gaëtan.

Can you please send me offline these two files? Regards, Fabio Estevam

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.
