Sony VPCSA290X Guia Do Utilizador

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?

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

Follow steps 1 to 4 in How do I change the sound output device? 

.

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

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.
