Connect the Sony HTIB to the TV using HDMI for video.
Connect FIOS to the TV using HDMI for video.
Connect FIOS to the Sony HTIB using optical for audio. (The Sony box doesn't have any HDMI inputs.) Check the FIOS box configuration to make sure it sends DD 5.1 on channels that have it. It may default to stereo instead.
The HDMI jacks on the TV are inputs, not outlets, btw.
