<pre>PulseAudio has programming interfaces for controlling the volume, which is used
by the volume control applet in gnome among other programs. Do you want access
limitations to that interface, or are you only talking about the alsa mixer
interface?
The access to the alsa mixer is governed by the permission bits on
/dev/snd/controlC*. There's nothing pulseaudio can do about that. It's up to
the distribution to manage the device permissions.
What other programs do you have in mind, by the way? Deliberately malicious
applications or something else?</pre>
