I checked the volume in the raspbian volume utility
also as I said if I restart my program, it is still the same vollume
values, not my values
how does it work then ?
how to I submit/commit my volume settings ?
is there no wiki or anything explaining all these ?

What do you mean by "kept as default"?
setOutputVolume(0,100);
setOutputVolume(1,100);
setOutputVolume(2,100);
setOutputVolume(3,100);
setOutputVolume(4,100);
void setOutputVolume(int index,int volume)
{
pa_operation* o;
currentVolume.values[0]=volume;
currentVolume.values[1]=volume;
if (!(o = pa_context_set_sink_volume_by_index(context, index,
¤tVolume, NULL/*volumeCallback*/, NULL)))
{
printf("pa_context_set_source_volume_by_index() failed\n");
debugContextState(pa_context_get_state(context));
return;
}
printf("new volume [%d]: %d
%d\n",index,currentVolume.values[0],currentVolume.values[1]);
When you print this message, do you expect the volume at the server end
to have already changed? All interactions with the server are
asynchronous, so at this point in your code libpulse has only queued
the "set sink volume" command to be sent. The command has not yet
reached the server.
