The TV does not support HDCP (High-bandwidth Digital Content 
Protection).

Refer to the instruction manuals for the TV and check the TV’s specifications.

The unit is set not to output audio input through HDMI jacks from 
the SPEAKERS terminals.

In “Audio Output” in the “Setup” menu, set “Amp” to “On” (p.74).

The number of devices connected to the HDMI OUT jack exceeds 
the limit.

Disconnect some of the HDMI devices.

The TV is set to output audio from the TV speakers.

Change the audio output setting on your TV so that the TV audio is output from the 
speakers connected to the unit.

A TV that does not support ARC is connected to the unit only with 
an HDMI cable.

Use a digital optical cable to make an audio connection (p.20).

(If the TV is connected to the unit with an audio cable)
The TV audio input setting does not match the actual connection.

Use “TV Audio Input” in the “Setup” menu to select the correct audio input jack 
(p.74).

(If you are trying to use ARC)
ARC is disabled on the unit or TV.

Set “ARC” in the “Setup” menu to “On” (p.75). Also, enable ARC on the TV.

The playback device is set to output 2-channel audio (such as 
PCM) only.

To check it, use “Signal Info” in the “Option” menu (p.66). If necessary, change 
the digital audio output setting on the playback device.

The unit is too close to another digital or radio frequency device.

Move the unit further away from the device.

The cable connecting the unit and playback device is defective.

If there is no problem with the connection, replace with another cable.

The volume of the unit is too high.

Turn down the volume. If “ECO Mode” is set to “On”, set it to “Off” (p.78).

A device connected to the unit’s output jacks is not turned on. 

Turn on all devices connected to the unit’s output jacks.
