playing a sound and suspending at the same time => no sound at resume on 2.6.39

[GNUtoo]

doing the following result in not beeing to play a sound anymore at resume:

aplay 05.wav
echo mem > /sys/power/state #in a new console
#press the power button
#still no sound
killall aplay
aplay 05.wav #still no sound

[GNUtoo]

The kernel used is this one:
​https://gitorious.org/shr/linux/commits/shr-2.6.39-nodrm

[GNUtoo]

it does it too with speaker-test

Also, after resume:

amixer -qc0 cset numid=92,name='Left Mixer Left Playback Switch' off
amixer -qc0 cset numid=92,name='Left Mixer Left Playback Switch' on

makes it not silent again.
