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 156).
❑ 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 156).
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 the configuration of your computer.
