When you adjust the Volume slider or the Balance slider in the Sound item in Control Panel in Windows Vista, the level setting may change slightly after you click OK. The exact setting for the Volume slider or for the Balance slider is not retained.

For example, the level setting may change slightly in the following scenario:

•	You open the Sound item in Control Panel, you select a device on the Playback tab, and then you click Properties.
•	You click the Levels tab, and then you adjust the Volume slider level or the Balance slider level.
•	You click OK, and then you reopen the dialog box.

Note This issue may be easier to detect if you switch to decibel (dB) view. To do this, right-click the value box that shows the current level, and then click decibels.

This issue occurs because the sliders automatically snap to the nearest level that is supported by the sound device when you click OK. The behavior depends on the specific sound device.
