hi,
I try to set the volume on source #0 (the audio jack of my raspbery pi)
but it does not work
void setVolume(int index,int volume) // where index is 0
{
pa_operation* o;
currentVolume.values[0]=volume;
if (!(o = pa_context_set_source_volume_by_index(context, index,
¤tVolume, NULL/*volumeCallback*/, NULL)))
{
printf("pa_context_set_source_volume_by_index() failed\n");
return;
}
printf("new volume: %d\n",currentVolume.values[0]);
pa_operation_unref(o);
}

strangeley, if I plug my audio usb card wich is on index 1,and still
change the volume on source index 0, it works
