Specs on the Sony show one analog input on the front. Can't find info on the TV.
If the TV has a headphone out or line level analog audio out then that connection is all you need.
If the TV has optical audio out you will need a DAC to convert that to analog.
If the TV has no audio outputs then you can get the audio directly from the box. If it doesn't have av out then you will need an HDMI audio extractor.
