Normally no applications should keep the sound card open. I had to make this
commit for cruxus engine:
maybe there is some other place where close on the sound card is not called.
We should reproduce the bug and place some debug prints here:
Especially we should watch snd_pcm_open() and snd_pcm_close().

Not very much gsmheadset.state is the one i havent tested at all.

After some calls with ringtone from suspend i could see that media server has
the soundcard open:
was showing mediaserver.
Btw we have also other options - there is audio plugin for pulseaudio too.
