I am trying to use speaker-test on my sam9g20 board, with the Wolfson 
wm8731, but I can't have any tone...
Instead it returns this error:
# speaker-test -c 2 -t1

speaker-test 1.0.14

Playback device is default
Stream parameters are 48000Hz, S16_LE, 2 channels
Using 16 octaves of pink noise
Rate set to 48000Hz (requested 48000Hz)
Buffer size range from 16 to 1073745880
Period size range from 0 to 0
Using max buffer size 1073745880
Periods = 4
was set period_size = 0
was set buffer_size = 8192
Unable to set sw params for playback: Invalid argument
Setting of swparams failed: Invalid argument

So I tried:
# speaker-test -D"name" -c 2 -t1, but I don't know exactly what should I 
pass as "name".
I did: aplay -L to list all the devices, but I don't see anything...

Is anybody got an idea here?
