Kernel 4.1 & Audio

Hi,

I’ve disabled the capemanager in the kernel 4.1.
And I put manually the cape in the dtb.

The kernel seems to have no problem with it :

dmesg | grep tlv320aic3x

[ 8.553572] davinci_evm sound: tlv320aic3x-hifi <-> 48038000.mcasp mapping ok

Linux is ok with it :
aplay --list-devices

**** List of PLAYBACK Hardware Devices ****
card 0: EVM [DA830 EVM], device 0: AIC3X tlv320aic3x-hifi-0 []
Subdevices: 1/1
Subdevice #0: subdevice #0

I tried to play a song to test the output :

aplay --file-type wav /home/debian/Zelda.wav

Playing WAVE ‘/home/debian/Zelda.wav’ : Signed 16 bit Little Endian, Rate 20000 Hz, Mono

But nothing came out !

Any idea ?
