pnmixer 0.7.2 Simple mixer application designed to run in system tray
PNMixer is a simple mixer application designed to run in system tray. It integrates nicely into desktop environments that don't have a panel that supports applets and therefore can't run a mixer applet. In particular, it's been used quite a lot with fbpanel and tint2 but should run fine in any system tray.
PNMixer is designed to work on systems that use ALSA for sound management. Any other sound driver like OSS or FFADO are, currently, not supported. There is no official PulseAudio support, at the moment, but it seems that PNMixer behaves quite well anyway when PA is running.
