No TV sound is output from the
system.
 Check the type and connection of the
HDMI cable or optical digital cable
that is connected to the system and
the TV (refer to the supplied Startup
Guide).
 When the system is connected with a
TV compatible with Audio Return
Channel, make sure the system is
connected to an ARC-compatible
HDMI input terminal of the TV (refer to
the supplied Startup Guide). If sound
is still not output or if sound is
interrupted, connect the optical
digital cable (supplied) and set on the
system [System Settings] - [HDMI
Settings] - [Audio Return Channel] to
[Off] (page 43).
 If your TV is not compatible with
Audio Return Channel, connect the
optical digital cable (supplied) (refer
to the supplied Startup Guide). If the
TV is not compatible with Audio
Return Channel, TV sound will not be
output from the system even if the
system is connected to the TV's HDMI
IN jack.
 Switch input of the system to [TV]
(page 11).
 Increase the volume on the system or
cancel muting.
 Depending on the order in which you

is displayed on the front panel display
of the system. If this happens, turn on
the TV first, then the system.
 Set the speakers setting of the TV
(BRAVIA) to Audio System. Refer to
the operating instructions of your TV
regarding how to set the TV.
The sound is output from both the
system and the TV.
 Mute the sound of the system or the
TV.
The TV sound from this system lags
behind the image.
 Set [A/V SYNC] to 0 msec if it is set to
the range between 25 msec and 300
msec (page 21).
No sound or only very low-level
sound of the device connected to

 Press SW  + on the remote control
to increase the subwoofer volume
(page 21).
 The subwoofer is for reproducing
bass sound. In the case of input
sources that contain very little bass
sound components (i.e., a TV
broadcast), the sound from the
subwoofer may be difficult to hear.
The surround effect cannot be
obtained.
 Depending on the input signal and
the sound field setting, surround
sound processing may not work
effectively. The surround effect may
be subtle, depending on the program
or disc.
