Volwheel is a nice little Perl script panel applet which provides a lightweight sound/volume controller on your chosen panel/toolbar. I use Tint2 on my Openbox desktop, and volwheel is always a part of my setup.
First download Volwheel
Untar it
tar zxvf volwheel-0.2.8.tar.gz
Dependencies
sudo apt-get install libgtk2-trayicon-perl
Install
cd volwheel-0.2.8
sudo ./install.pl
Copy Icons to System
sudo mkdir -p /usr/local/share/volwheel/icons
cd icons
sudo cp -a * /usr/local/share/volwheel/icons
Copy Libs to System
cd ..
cd lib
sudo cp -a * /usr/lib/perl5
Launch Volwheel
volwheel &
Change the theme and settings (I use static + speaker-black)
Right click on Volwheel icon, choose Preferences
Autostart for Openbox
vim .config/openbox/autostart.sh
Add this line:
## Start volumeicon after a slight delay
(sleep 5s && volwheel) &
That’s it, now you have a nice Perl volume icon.
