Troubleshooting

What should I do if I find dropped frames during video playback?

If the video playback window is overlaid with another window, you may encounter dropped frames or find playback performance degraded. Move the video playback window to where it will be unlikely to be overlaid with another window or maximize the video playback window.

What should I do if I do not hear the sound from the sound output device connected to the HDMI output port, optical output port, or headphones jack?

❑You need to change the sound output device if you want to hear sound from the device connected to a port, such as the HDMI output port, optical output port, or headphones jack. For the detailed procedure, see How do I change the sound output device? (page 154).

❑If you still hear no sound from the sound output device, follow these steps:

1 Follow steps 1 to 4 in How do I change the sound output device? (page 154).

2 On the Playback tab, select the HDMI or S/PDIF icon and click Properties.

3 Click the Advanced tab.

4 Select the sample rate and bit depth (for example, 48000 Hz, 16 bit) which the device supports. 5 Click OK.

Why do sound interruptions and/or dropped frames occur when I play high-definition videos, such as those recorded with the AVCHD digital video camcorder?

Playing high-definition videos requires substantial hardware resources, such as CPU, GPU, or system memory performance on your computer. During the video playback, some operations and/or functions may become unavailable, and sound interruptions, dropped frames, and playback failure may occur depending on your hardware specifications.
