Comment 31 for bug 893402

@Sebastien,

Did you try it on Linaro 12.01? I can't get it work at all with plughw:0,0 & plughw:0,6.

On 0,0 it never end the playback and crash in kernel. And speaker-test does not work with error:
root@linaro-developer:/proc/asound# speaker-test -D plughw:0,0 -t s -c 2 -l 1 -F S32_LE

speaker-test 1.0.24.2

Playback device is plughw:0,0
Stream parameters are 48000Hz, S32_LE, 2 channels
Sine wave rate is 440.0000Hz
Rate set to 48000Hz (requested 48000Hz)
Buffer size range from 24 to 16384
Period size range from 12 to 8184
Using max buffer size 16384
Periods = 4
Unable to set nperiods 4 for playback: Invalid argument
Setting of hwparams failed: Invalid argument

On 0,6 it try to play but I don't hear anything. And it crash in kernel too:

Could you test it with your kernel?
