Sony STR-DH790 Operating Instructions Manual page 49

No sound or only a very low level of
sound is heard from specific
speakers.
• Connect a pair of headphones to the
PHONES jack to verify that sound is
output from the headphones. If only one
channel is output from the headphones,
the device may not be connected to the
receiver correctly. Check that all of the
cables are fully inserted into the jacks on
both the receiver and the device.
If both channels are output from the
headphones, the front speaker may not
be connected to the receiver correctly.
Check the connection of the front
speaker that is not outputting any sound.
• Make sure you have connected to both
the L and R jacks of an analog device, as
analog devices require both L and R jack
connections. Use a stereo audio cable
(not supplied).
• Adjust the speaker level.
• Check that the speaker settings are
appropriate for the setup using "AUTO
CAL" in the "<A.CAL>" menu or
"PATTERN" in the "<SPKR>" menu. Then
check that sound is output from each
speaker correctly using "T. TONE" in the
"<LEVEL>" menu.
• Check that the subwoofer is connected
correctly and securely.
• Make sure you have turned on your
subwoofer.
• Depending on the selected sound field,
sound may not be available from the
subwoofer (page 41, 42).
There is no sound from a specific
device.
• Check that the device is correctly
connected to the corresponding audio
input jacks.
• Check that the cable(s) used for the
connection is (are) fully inserted into the
jacks on both the receiver and the device.
• Check the "IN MODE" setting in the
"<INPUT>" menu.
• Check that the device is correctly
connected to the corresponding HDMI
jack.
• The HDMI settings of some playback
devices need to be configured. Refer to
the operating instructions supplied with
each device.
• Be sure to use a High Speed HDMI Cable
with Ethernet when you view images or
listen to sound, especially for 1080p,
Deep Color (Deep Colour), 4K or 3D
transmission. Premium High Speed HDMI
Cable with Ethernet that supports
18 Gbps is required for 4K/60p 4:4:4,
4:2:2 and 4K/60p 4:2:0 10 bit etc.

receiver while the home menu is
displayed on the TV screen. Press HOME
to exit the home menu.
• Audio signals (format, sampling
frequency, bit length, etc.) transmitted
from an HDMI jack may be suppressed by
the connected device. Check the setup of
a device connected via an HDMI cable if
the image is poor or the sound does not
come out of the device.
• When a connected device does not
support the copyright protection
technology (HDCP), the image and/or the
sound from the HDMI TV OUT jack may be
distorted or may not be output. If this is
the case, check the specifications of the
connected device.
• Set the image resolution of the playback
device to more than 720p/1080i to enjoy
High Bitrate Audio (DTS-HD Master
Audio, Dolby TrueHD).
• The image resolution of the playback
device may need to be configured to
certain settings before you can enjoy
DSD and Multi Channel Linear PCM. Refer
to the operating instructions of the
playback device.
• When you connect the receiver to a video
device (projector, etc.), sound may not be
output from the receiver. In this case, set
"AUDIO.OUT" to "AMP" in the "<HDMI>"
menu.
