Press the (Quick Settings) button or HOME button on the supplied remote control: Select Settings. Under the TV category, select Sound, Display & Sound or BRAVIA Settings. Select Audio output.

If your TV doesn’t use RCA connectors for audio output, it may have a headphone out port (3.5mm port). You can use this to connect your TV to the speakers. They’re the same connector used on phones, tablets, laptops, etc. For this, you’ll need to use a 3.5mm audio jack on the TV end and a RCA jack on the speaker end.

The three most common methods to allow the television sound be heard through the speakers of a stereo receiver or home theater system are:

1. Option 1: HDMI connection using the Audio Return Channel (ARC) feature (Preferred method)
2. Option 2: Connection using Optical Digital Cable or Coaxial Digital Cable (Digital audio)

First up, if you have an older TV set such as a CRT (Cathode Ray Tube) type or even an early flat-screen TV, then your device probably lacks both analog and digital audio outputs. That’s because before HDMI cables were introduced in the year 2002, TVs rarely had audio outputs of any kind.

Digital fiber optic cables are used to carry sound to and from a number of different audio/video devices. If you have a cable or satellite set-top box or DVR you could also plug the audio output of that box directly into your home theater system.

S/PDIF (Sony/Philips Digital Interface) is a type of digital audio interconnect used in consumer audio equipment to output audio over reasonably short distances. The name stands for Sony/Philips Digital Interconnect Format but is also known as Sony/Philips Digital Interface.

Either is fine as long as you know what you’re in for with the SPDIF or optical format. Optical carries 8 channels at 44.1/48 kHz while SPDIF carries only 2 channels or is in stereo. Coaxial with SPDIF might also be the way to go since the more expensive optical cables can’t be bent or pinched tightly.

FAQ :: How to connect audio output through SPDIF?

1. Connect a SPDIF bracket cable (coaxial+optical mixed) into MB SPDIF OUT connector.
2. Check the SPDIF Bracket optical LED must be light-up.
3. Speaker connect to H/W Digital Decoder.
4. Connect SPFID with coaxial cable.
5. Connect SPDIF with Optical cable.

For example, TOSLINK is mostly used for connecting Dolby Digital decoders to sound equipment or to connect computers to AV receivers or consoles. In contrast, you will find SPDIF with coaxial and RCA is often used for connecting DVD players with receivers, such as speakers and TVs.

Both HDMI and optical pass digital audio from one device to another. Both are better than analog (the red and white cables). The biggest difference is that HDMI can pass higher-resolution audio, including the formats found on Blu-ray: Dolby TrueHD and DTS HD Master Audio.

In terms of audio quality, aux is more open to line loss and interference. Higher quality aux cables can also help as they’re better shielded. Optical isn’t foolproof either. Though not prone to interference in the way that aux is, digital can ‘lose’ data, especially over longer cable runs.

A lot of TVs will not let you connect both HDMI and optical cables at the same time, even if they have both of these ports available. You will be able to insert both – optical and HDMI cord and have the audio and video signals coming through both of them.

A common question that gets asked is, “Do I need optical audio if I have HDMI?” If your AV equipment has an HDMI port, then in most cases it would be best to transfer the audio signals via HDMI. This is because HDMI supports all types of audio signals and you can send all the video and audio signals via one cable.

HDMI ARC removes the need for an optical cable and allows you to send audio ‘downstream’ from a compatible HDMI socket on your TV to a compatible HDMI ARC socket on a soundbar or AV receiver.
