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
If all you have is a single application using the sound hardware, yes,
straight ALSA is probably the way to go.
Also, you probably don't need to run as root to interface with GPIO
pins. If you are using the /sys interface, you can chown / chgrp the
desired pins to a non-privileged user / group.
