PNMixer is a simple mixer application designed to run in your 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 a fork of OBMixer with a number of additions. These include:

• Volume adjustment with the scroll wheel
• Select which ALSA device and channel to use
• Detect disconnect from sound system and re-connect if requested
• Bind and use HotKeys for volume control
• Texual display of volume level in popup window
• Continous volume adjustment when dragging the slider (not just when you let go)
• Draw a volume level onto system tray icon
• Use system icon theme for icons and use mute/low/medium/high volume icons
• Configurable middle click action
• Preferences for:
  • volume text display
  • volume text position
  • icon theme
  • amount to adjust per scoll
  • middle click action
  • drawing of volume level on tray icon
