[Openal-devel] just calling ALutInit(0,0) costs 20% of CPU

I went to search a bit more on this, and found that an infinite loop with no
pause is done in the file alsa.c of the library,
within the function :
static ALuint ALSANoMMapProc(ALvoid *ptr);
the function is launched by a thread launched during the initialization
this function watches if a new sound has arrived and sent it to the alsa
the fact is even if there is nothing to play the loop is running,
so it requires a lot of memory..
Is this normal ?
