There is no audio when playing the Blu-ray Disc or HD DVD titles.
Issue
Can't hear any sound during Blu-ray Disc or HD DVD playback.
Cause
1. The volume is set too low or muted.
2. The speaker line is not plugged into the right Audio Out connector.
3. The sound card driver is too old.
4. You may have set the output mode to digital (S/P DIF) mode.
Solution
1. Check the Master Volume by double-clicking the speaker icon in the system tray. If the Mute check box for Master Volume or Wave is checked, please uncheck it.
2. Make sure your speakers are powered on with appropriate volume. Check if the speakers' audio line is correctly connected to the speaker out or audio out hole. The color of the hole should be light green.
3. Update your sound card driver. Please visit the Web site of your sound card manufacturer and download the latest driver for your sound card.
4. Use the configuration tool come with your sound card and switch off the S/P DIF output option if you intend to output the sound via a normal speaker. Similarly, if you intend to output the sound to an amplifier, please be sure to switch the output to digital (S/P DIF) mode.
