When the Stereo or Mono listening mode is selected,
only the front speakers and subwoofer produce
sound.
—
In the Mono listening mode, only the front speakers
output sound if the “Output Speaker” setting is set
to “Left/Right”.
Check the Speaker Configuration.
If you use the Dolby Pro Logic IIx Movie, Dolby Pro
Logic IIx Music, or Dolby Pro Logic IIx Game lis-
tening mode with a mono source, such as an AM
radio station or mono TV program, the sound is con-
centrated in the center speaker.
—
In the Mono listening mode, only the front speakers
output sound if the “Output Speaker” setting is set
to “Center”.
Make sure the speakers are configured correctly.
When the T-D (Theater-Dimensional), Stereo or
Mono listening mode is selected, the surround
speakers produce no sound.
—
Depending on the source and current listening mode,
not much sound may be produced by the surround
speakers. Try selecting another listening mode.

While Powered Zone 2 is being used, playback in the
main room is reduced to 5.1-channels and the front
high, and surround back speakers produce no sound.
When you play source material that contains no
information in the LFE channel, the subwoofer pro-
duces no sound.

Check the digital audio output setting on the con-
nected device. On some game consoles, such as
those that support DVD, the default setting is off.
—
With some DVD-Video discs, you need to select an
audio output format from a menu.
—
Depending on the input signal, some listening modes
cannot be selected.
If no surround back speakers, and front high speak-
ers are connected, or the Zone 2 speakers are being
used, 6.1/7.1 playback is not possible.
—
You can not always select all of the listening modes,
depending on the number of the speakers connected.
Check to see if a maximum volume has been set.
If the volume level of each individual speaker has
been adjusted to high positive values, then the maxi-
mum master volume possible may be reduced. Note
that the individual speaker volume levels are set
automatically after the Audyssey 2EQ

Room Cor-
rection and Speaker Setup function has been com-
pleted.
Using cable ties to bundle audio cables with power
cords, speaker cables, and so on may degrade the
audio performance, so don’t do it.
—
An audio cable may be picking up interference. Try
repositioning your cables.
—
Make sure the source material is Dolby Digital,
Dolby Digital Plus, and Dolby TrueHD.
When DTS program material ends and the DTS bit-
stream stops, the AV receiver remains in DTS listen-
ing mode and the DTS indicator remains on. This is
to prevent noise when you use the pause, fast for-
ward, or fast reverse function on your player. If you
switch your player from DTS to PCM, because the
AV receiver does not switch formats immediately,
you may not hear any sound, in which case you
should stop your player for about three seconds, and
then resume playback.
—
With some CD and LD players, you won’t be able to
playback DTS material properly even though your
player is connected to a digital input on the AV
receiver. This is usually because the DTS bitstream
has been processed (e.g., output level, sampling rate,
or frequency response changed) and the AV receiver
doesn’t recognize it as a genuine DTS signal. In such
cases, you may hear noise.
—
When playing DTS program material, using the
pause, fast forward, or fast reverse function on your
player may produce a short audible noise. This is not
a malfunction.
—
Since it takes longer to identify the format of an
HDMI signal than it does for other digital audio sig-
nals, audio output may not start immediately.
