the volume or mute key.

the volume on this receiver is not set to zero or mute.

such a system for the TV sound. Check if you
connected the HDMI cable to an HDMI1
ARC connection on the Home Theatre System.

the audio input on the Home Theatre System.
Sound should be heard from the HTS (Home Theatre
System) speakers.

when the audio or video file has DTS sound but the
Home Theatre System has no DTS sound processing.
You can fix this by setting the Digital out format of
the TV to Stereo.
Press (Home) > Settings > All
settings > Sound > Advanced > Digital out format
