We are having problems trying to put system in "suspend" state because some
clock are kept alive. These clocks are audio related.

AudioFlinger's constructor calls openOutputStream method, which opens ALSA
pcm interface by calling "snd_pcm_open" (ALSA API). In ALSA kernel driver it
means that resources will be allocated and hardware codec will be on.
However, even if no output stream is being transmitted, stream channel is
never closed making audio resources being active always at kernel level.
This prevents the system to sleep.

I think we should only open ALSA PCM interface when needed and not directly
from boot-time, but it seems that openOutputStream method is the right place
to call "snd_pcm_open", isn't it? Is there any other better place to open
ALSA interface? Or any other solution?
