Volume Properties is available only when using DirectSound mode. Use it to adjust recording volumes and select or unselect recording sources. Make sure the Volume device selected is the same as the recording device selected in the Device tab (it is not matched automatically if more than one recording device is available).
A volume fader, edit box, and checkbox are shown for each source. To select a source, check the appropriate checkbox. If your sound card supports a master control, make sure that the Mute all setting is not checked and that the master volume is not zero.
You can use the Monitor input on visuals setting under the Record tab to activate the visuals without recording.
Note that volumes are changed instantly remain changed even if Cancel is used to close the Properties window.
To select a different recording device, use the Device tab.
