Audio Signals
Digital audio signals received by the HDMI IN jacks are output by the speakers and headphones connected to the AV receiver. Normally, they are not output by the HDMI OUT, unless the “Audio TV Out” setting is set to “On” (see page 81).
p.81 “Hardware Setup” menu. (on remote) Audio TV Out
This preference determines whether audio received at
the HDMI IN is output by the HDMI OUT. You may
want to turn this preference on if your TV is connected
to the HDMI OUT and you want to listen to the audio
from a component that’s connected to an HDMI IN,
through your TV’s speakers. Normally, this should be set
to “Off”.
