Possible Solution
There is no audio
from the center
and/or surround
speakers of a
home theater
receiver connected
to the QIP set-top
Not all Dolby® Digital programs feature full 5.1 surround sound. In some
cases, the programs may only contain left and right stereo audio.
•
Verify that the S/PDIF cable (coaxial or optical) is firmly connected to the
QIP set-top and the home theater receiver.
•
Verify that the home theater receiver is set to a surround sound audio
mode (Dolby Digital, Dolby Pro Logic II®, Dolby Pro Logic®).

Verify that the receiver is properly configured to work with all connected
speakers.

If the QIP set-top video output is connected to a home theater unit, verify
that the home theater unit is powered on and set to the appropriate input
source.

If the QIP set-top video output is connected to a TV through an HDMI
connection, power off the TV and then power off the QIP set-top. Wait one
second and then power on the devices.
Not all HDTVs can display every output format (1080i, 720p, 480p, or 480i)
available on the QIP set-top. To select a different format:

Widescreen TVs display 4:3 programs in this format unless set to Stretch.
Turn on the 4:3 OVERRIDE feature in the User Settings menu. This enables
most widescreen TVs to stretch the video to fill the screen (see your TV
manual for information about stretching 4:3 video).
•
If the QIP7000 series is connected to a widescreen TV, verify that the TV
TYPE is set to 16:9 in the User Settings menu.
Many HD programs are broadcast in pillar-box format with black bars to the
left and right of the picture. These programs are broadcast in 16:9 HD
formats, even though the video is not 16:9.
