Here’s how you can establish a connection using digital optical.

  1. Connect your Samsung smart TV digital optical audio output to the matching digital optical audio input on your home theater
  2. Access a 2 or 5.1 channel non-decoded audio signal on your Samsung Smart TV, which your home theater can decode correctly.
  3. Hear the sound coming from your home theater’s speakers.
  4. Adjust the audio quality settings on your tv. Search for the alternative named PCM to resolve the problem.

2. RCA Connection

Another method to connect a Samsung smart TV is through an RCA connection.  If you want to improve the audio quality of your TV, this is the most straightforward choice. It is just a matter of linking your TV’s analog stereo output, also known as RCA outputs, to the appropriate external audio system.

Here’s how you can establish a connection using RCA.

  1. Connect the mini-stereo plug (3.5mm) to your TV’s audio output using the analog stereo cables.
  2. Then connect the RCA cables from your TV to a specific matching audio output on the home theater receiver.
  3. Switch on the home theater system and follow the on-screen directions. This will allow you to check for any extra audio settings.
  4. Hear the audio, by choosing the input on your home theater system.
  5. Connect via a 3.5mm or 1/8-inch mini-jack if your system lacks an RCA. If this is the case, add the stereo mini-jack to the RCA cable adapter.

3. HDMI Connection

This Audio Return Channel (ARC) is another excellent method of linking your Samsung Smart TV to your home theater. If you want to use this connection, your Smart TV must have an HDMI-ARC [1] input (which most Samsung smart TVs have).

  • Attach the HDMI cable to both your home theater’s HDMI-ARC output and your TV’s HDMI connection.
  • Turn on your Samsung smart TV and your home theater and check if the connection established is successful.

4. Bluetooth

Bluetooth can also be used to transmit audio from your TV to your home theater. This choice is advantageous since no cable is needed. The whole connection is wireless. You can conveniently connect using the Samsung Share button on your Smart TV in this process.
