SYMPTOMS
Consider the following scenario. On a computer that is running Windows Vista, you open the Sound item in Control Panel. Then, you open the Properties dialog box for an installed device that uses one of the following interface formats:
 * High-Definition Multimedia Interface (HDMI)
 * Sony/Philips Digital Interface (S/PDIF)

However, when you click the Supported Formats tab in the Properties dialog box for the device, you notice that all the check boxes are unexpectedly selected. For example, the following check boxes are selected:
 * DTS Audio
 * Dolby Digital
 * Microsoft WMA Audio
 * 44.1 KHz
 * 48.0 KHz
 * 88.2 KHz
 * 96.0 KHz
 * 176.4 KHz
 * 192.0 KHz

You experience this problem even though the following conditions are true:
 * You did not select all the check boxes.
 * The device does not support all these selected formats.

When this problem occurs, you may not receive sound from the device.



CAUSE
This problem occurs in the following scenario:
 * 1) After you click the Supported Formats tab for the device, you click another tab in the Properties dialog box. Then, you click Cancel.
 * 2) You reopen the Properties dialog box for the device, and then you click the Supported Formats tab again.

In this scenario, the settings that were previously configured on the Supported Formats tab are not maintained. Windows Vista incorrectly selects all the check boxes.
