[pulseaudio-discuss] pa_context_set_source_volume_by_index() failed

[pfl]

I dont know about this

my problem is that raspbery pi has gpio header and the program needs to 
be ran as root to use these gpio

but if pulseaudio is not made nor supported to be run as root, then 
maybe I should use something else (alsa?)

the only thing I need is my app to set the mic input and speaker output 
volumes

nothing else, this all really starts to get complicated just to set the 
input/output of the system
