Note The symptoms of this problem may vary, depending on the specific configuration. For example, any of the following may affect this scenario:
- In most cases, DTS is used to store 5.1-channel audio. However, DTS also supports 2-channel stereo.
- A program that plays DVDs, such as Windows Media Center, may only output DTS audio when it is configured to do this. This behavior may affect what you hear. For example, you may hear no audio from the DVD when this problem occurs.
- Windows Vista tries to use PCM audio for error dialog box notifications. Therefore, you may hear these notifications on a home theater system when this problem occurs.
- When the Dolby Digital check box is selected, you cannot hear sound through AC3-compliant and non-DTS-compliant High-Definition Multimedia Interface (HDMI) devices.
