Gnome and Pulseaudio - Some applications start with volume muted
I'm trying to use some fullscreen applications that use OpenAL, but for some reason, the pulseaudio plugin is always muted when I start the program. Unfortunately, if I leave fullscreen mode, the program continues to trap the mouse and when I close the program, I can no longer set the volume.
The program specifically is openarena.
Is there any way I can set the volume while this program is running without using the GUI for the sound settings in Gnome 3.8?
This is Arch linux.
