I can watch TV via TV tuner card in PowerCinema, but I can't hear anything. What should I do?

1. Check the speaker is opened and the volume does not minimize.
2. Please go to general page in TV Settings to check audio device first. It should be selected by "audio line in" item. If it is not this one, please choose the correct one.
3. Once you still hear nothing form speakers, please check the system audio whether the "Line-in" item is mute. It should be unchecked in mute selection.
4. If you need reset audio setting in PC, please follow the process below:
   a. From your Windows (OS) Start Menu, please follow the directions to access Volume Control:Start -> Programs -> Accessories -> Entertainment -> Volume Control
   b. A dialogue window will appear for Volume Control, please follow the directions to select Playback options: Options -> Properties -> Select "Playback", check every option, click OK and adjust volume.
   c. Then follow these directions back to access the Recording options -> Properties -> Select "Recording", check every option click OK and adjust volume.

You can use Windows Recording program to record a period of audio to test that your setting is correct or not, if you can record sound and play with no problem, PowerCinema should have no problem as well.
