aplay noise

["Mathieu Rondonneau" <mathieu.rondonneau@polymtl.ca>]

Hi all,

thanks for your answers.

I have another problem with my driver... another one ;)

When i try to play a sound with aplay, there is an horrible noise like: 
"tatatatatatatat" (like gun shoots)

I don't understand why.
I'm trying to playback a wav file, but i hear some strange noise, not the
data corresponding to the wav file.
I compared the data of the wav file and the data in the copy operator
(before they sent to the codec). They seam to be the same.

This is what the aplay -v tell me, maybe it can help.
 
aplay -v voice-8k-16bit-stereo.wav

Playing WAVE 'voice-8k-16bit-stereo.wav' : 
Signed 16 bit Little Endian, Rate 8000 Hz, Stereo

Plug PCM: Hardware PCM card 0 'codec a ' device 0 subdevice 0

Its setup is:
