Check TV volume
We know, this one seems obvious, but just in case -- make sure the volume on your TV is not at the lowest setting or muted.
Check cable connections
Make sure your HDMI/optical connectors are plugged in.
Check for any breakage/fraying in the cable.
Reverse the ends of the cable or try using a different HDMI cable.
