Yamaha RX-A3060 Owner's Manual page 165

Problem
No sound from the TV (when HDMI Control is used).
No sound from the Zone2 TV (connected to the unit
with HDMI).
Only the front speakers work on multichannel audio.
Noise/hum is heard.
The sound is distorted.
The sound is interrupted.
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 audio output from the HDMI OUT 2 (ZONE OUT) jack is disabled.
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.
If the HDMI OUT 2 (ZONE OUT) jack is assigned to Zone2 or Zone4, HDMI
audio output may be interrupted during some zone operations due to
internal circuitry switching.
En
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.41).
Use "TV Audio Input" in the "Setup" menu to select the correct audio input jack (p.140).
Set "ARC" in the "Setup" menu to "On" (p.141). Also, enable ARC on the TV.
Set "Audio Output" in the "Setup" menu to "On" (p.147).
To check it, use "Audio Signal" in the "Information" menu (p.151). 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" in the "Setup" menu is set to "On", set it to "Off"
(p.150).
Turn on all devices connected to the unit's output jacks.
For details, see "Connecting an HDMI-compatible device to play back videos/audio"
