Yamaha RX-S600 Owner's Manual page 103

Problem
No sound from the TV (when HDMI Control is
used).
Only the front speakers work on multichannel
audio.
Noise/hum is heard.
The sound is distorted.
Cause
The TV is set to output audio from the TV speakers.
A TV that does not support ARC is connected to the unit only with
an HDMI cable.
(If the TV is connected to the unit with an audio cable)
The TV audio input setting does not match the actual connection.
(If you are trying to use ARC)
ARC is disabled on the unit or TV.
The playback device is set to output 2-channel audio (such as
PCM) only.
The unit is too close to another digital or radio frequency device.
The cable connecting the unit and playback device is defective.
The volume of the unit is too high.
A device connected to the unit's output jacks is not turned on.
Remedy
Change the audio output setting on your TV so that the TV audio is output from the
speakers connected to the unit.
Use a digital optical cable to make an audio connection (p.21).
Use "TV Audio Input" in the "Setup" menu to select the correct audio input jack
(p.84).
Set "ARC" in the "Setup" menu to "On" (p.85). Also, enable ARC on the TV.
To check it, use "Signal Info" in the "Option" menu (p.76). If necessary, change
the digital audio output setting on the playback device.
Move the unit further away from the device.
If there is no problem with the connection, replace with another cable.
Turn down the volume. If "ECO Mode" is set to "On", set it to "Off" (p.88).
Turn on all devices connected to the unit's output jacks.
