[PATCH 1/1] mx27_3ds: Add sound support

[gcembed@gmail.com (Gaëtan Carlier)]

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.
Ga?tan.
