The two most common connections used to hear TV sound from the A/V receiver or home theater system speakers are:

Option 1: HDMI® connection using the ARC feature
Option 2: Connection using an HDMI cable, Coaxial Digital, Optical Digital, or Audio cable
Which option you use will depend on the connection ports on your products. If your TV and audio system both support the ARC feature, we recommend using Option 1 to connect your products, otherwise use Option 2.
Note: For other possible connections and model-specific information about system settings, check the manuals supplied with your products.

Turn off the A/V receiver.
Connect the speaker wires to the speaker terminals on the rear of the A/V stereo receiver.
IMPORTANT:
For spring clip terminals, press down on the red (positive) or black (negative) clips and insert the speaker wire into the slot. Then, release the clips
For binding post terminals, loosen the red (positive) or black (negative) binding posts by turning them counter-clockwise. Insert the speaker wire into the slots under the binding posts and then turn the binding posts clockwise to tighten.
Connect the other end of the speaker wires to the corresponding speakers.

ARC features
Connecting an ARC-compatible audio system to an ARC-compatible TV allows the following:

Send audio from the TV to the audio system.
View and listen to movies and other content sent from the audio system and viewed on the TV.
Control functions that allow features such as using one remote for multiple devices.
To connect an ARC-compatible audio system to an ARC-compatible TV, a high-speed HDMI cable must be connected from the TV HDMI (ARC) IN port on the TV to the HDMI (ARC) OUT port on the A/V Receiver or Soundbar
An additional optical or analog audio cable is required to send sound to the audio system if either the TV or audio system isn't ARC-compatible
Note:
A High Speed HDMI Cable is needed to enable the ARC function

Pulse-Code Modulation (PCM) and the Dolby Digital® technology refer to different types of digital audio recordings. PCM is the conventional method for converting analog audio into digital audio. The PCM audio recorded on DVD is a two-channel digital, stereo audio track.

The Dolby Digital® technology, which was originally called AC3, was developed specifically for multi-channel applications, including film sound and digital surround sound in the home. Dolby Digital® technology uses a 5.1 or six channel format. The 5 channels include the Stereo left and right front channels, Stereo left and right surround channels, and the center channel. There is also, a Low Frequency Effects (LFE) channel for the subwoofer, which is counted as the 0.1 channel since it functions only when a deep base effect is needed.

A subwoofer (sub) is speaker, that is dedicated to the reproduction of low-pitched audio frequencies most commonly referred to as bass.

Passive Sub:

Passive subs are called passive because they need to be powered by an external amplifier or Audio/Video (A/V) receiver . This is similar to traditional speakers. The important thing to remember about a passive sub is that since the sub needs more power to reproduce low frequency sounds, the amplifier or A/V receiver needs to be able to send enough power to sustain bass effects reproduced by the sub without draining the power supply in the A/V receiver or amplifier.

Active or Powered Sub:

This type of sub is a self-contained speaker and amplifier. The speaker and amplifier are matched to for optimal performance and both are housed in the same enclosure. This takes a lot of the power load away from the A/V receiver and allows the receiver or amplifiers to just power the mid-range and tweeter speakers.
