Does your TV have only an optical digital audio output, only
analog RCA stereo out or no audio output options at all?
Often, TV manufacturers today only offer an optical audio output, a
stereo output or no output at all for
sound from your TV.
Many people do not have an audio/video receiver
with the capability to decode surround sound or have any audio device
with an optical input. So how do you get sound out from the TV to
external amplifiers or speakers for richer audio?
Depending on what gear you have or are willing to buy, there are many
options. Surround sound is available from a variety of sources
including over-the-air TV broadcasts, cable, satellite programming,
games (XBOX, Playstation), Blu-ray discs, DVD, and more. There are
converter boxes, switches, adapter cables and more, all available to
meet your audio goals.
Audio Goals -
1. Get surround sound or stereo sound from TV to a soundbar,
audio/video receiver, or stereo amplifier for richer sound.
2. Get surround sound or stereo sound from TV with no audio outputs.
3. Get sound from TV with only optical output - only using stereo
4. Get sound from multiple A/V sources when TV does not have enough
HDTV REAR PANEL
Some HDTVs have both analog audio out and digital audio outputs but
many TVs only have digital optical
audio out using an optical jack. In the
image above, the optical output jack is bottom right. It is labeled
DIGITAL AUDIO OUT
(OPTICAL). This is capable of surround sound or stereo (PCM). Some TVs
3.5mm audio output jack for stereo sound. Just above the optical,
labeled AUDIO OUT.
The image above shows a closeup of an optical jack. You use a Toslink
audio cable to connect to a soundbar or audio/video receiver or home
theater optical audio input. This way you can get surround sound or

cable which has 3.5mm at one end
and two RCA plugs at the other end to connect to stereo amplifier or

you are using a cable TV box or satellite TV receiver box to get your
TV programming, connect the analog audio outputs (white and red audio
OUT on the rear panel of the cable box) using a standard RCA stereo
cable (white and red) to your stereo amplifier inputs or wireless
speakers or other device.
The white and red analog audio outputs are
next to the yellow video output. These analog outs are usually
available on todays cable boxes for older TVs or VCRs but you can
hookup cables to the analog audio outs only and get the sound for your
TV show sent out to an amplifier and speakers. This also works for a
DTV converter box when using only an antenna for over the air TV
broadcasts. These converter boxes have RCA audio outputs to carry sound
to an amplifier.

Surround sound (when available) from the SPDIF output (7) can be used
to connect to a soundbar or home theater if TV has no audio output.
Usually requires a Toslink audio cable to connect.
Sometimes this solution works well and you do
not need to buy anything.
Some issues may occur with this solution such
as an audio delay. Your TV may have a feature to adjust audio delay but
if it does not and you are getting an audio delay, then go to the next

an audio converter.
This solution involves an audio converter box which
you will need to buy. Cost can be from $25 to $68 or so. These small
devices will accept the optical cable connection from your TV and allow
the stereo analog RCA output connection to your amplifier or other
There are some considerations here, such as:
Does the converter box actually convert the digital audio to analog or
whatever the TV is sending out from the optical output? Some converter
boxes actually convert
the digital bitstream to analog audio but others will only pass a PCM
2-channel signal to the analog RCA output.
If you see a warning regarding the audio converter box you intend to
buy such as the example below, be sure your TV can output 2-channel
stereo and not just 5.1 signals.
NOTE! This device will NOT decode
5.1-channel signals. It will ONLY convert 2-channel digital stereo
(PCM) input signals to analog stereo output. This will not work with
TVs that only output 5.1-channel digital signals!
The best converters will convert surround sound to 6 channel analog
audio. Look at the audio converter box. Does it have 6 RCA output jacks
just 2 RCA outputs?
The reason this is important is because some TVs do
not have the option to output their audio as 2-channel PCM over the
only as Dolby Digital
5.1, which needs to be decoded. Go into your TVs audio menu to check
which audio output options are available.
If your TV has the option to output
sound as 2-channel PCM or Dolby Digital 5.1, then you can buy a
only 2 RCA outputs (although you may want to buy a box with 6 analog
outputs). Set the TV to output PCM audio and connect a
standard stereo RCA cable to the converter box RCA outputs and then to
your inputs on a stereo receiver or other sound device.
If your TV can only output Dolby Digital 5.1 surround sound, then you
need a converter box which can decode the optical bitstream to 6
channel analog audio.

There are also soundbars
with optical inputs and wireless headphones
with optical inputs that may offer a solution. Soundbars for your TV
will give you some
enhanced sound while headphones will allow private TV listening. You
could also buy a home theater in a box system from Samsung, Sony, Onkyo
or Panasonic. These have optical inputs and give you richer sound from
loudspeakers. Just connect an optical audio cable from the TV to the
sound system and start enjoying better sound than your TV speakers can

HEADPHONES for TV
Headphones for a TV has many uses including private listening, volume increases for older folks without disturbing others, mobile listening and more.
There are basically three types of hookups, 1) wired, 2) wireless Bluetooth and 3) wireless RF. Wireless Bluetooth has some limitations such as about a
30 feet maximum distance of signal reliability and Bluetooth can suffer from an audio lag issue where the audio is not in synch with the video
creating a lip synch issue. More expensive Bluetooth headphones can sometimes fix this problem. Wired headphones are also limited in distance
and create a possible tripping hazard with the wire connection. Wireless RF headphones work up to 100 feet and do not suffer from audio lag.
Since TVs can have 3.5mm audio out, RCA stereo audio out or optical audio output, make sure to get a headphone transmitter unit with the proper connection
to your TV. Connect the TV to the headphone transmitter unit using an audio cable. If the TV has only optical audio output, connect the optical cable only from the TV to the headphone
transmitter unit. Next, set the TV to external speakers and the audio output to PCM. Headphones should have volume control.

Audio Return Channel - ARC
is a newer technology, part of the HDMI spec. Your TV must have ARC
capability and the other devices such as soundbar must also be ARC
capable. ARC lets
your digital TV output digital sound to an audio device and input
digital sound from the same audio device over a single
HDMI cable. ARC is
only available through the HDMI (ARC) port and only when the TV is
connected to an ARC-enabled A/V
With ARC you no longer need to connect an optical cable from the TV to
a soundbar or A/V receiver for sound. The same HDMI cable from the A/V
receiver to the TV which carrys DVD, Cable, satellite, Xbox, Bluray can
also carry, in the reverse direction, sound from the TV back to the A/V
receiver. You can send audio from internal TV sources like the
HDTV tuner, or
built-in web streaming apps to home theater, soundbar with HDMI.
Send out the audio from other
HDMI sources as the TV becomes the central hub.
The TV switches all the sources, and the audio for each one (Blu-ray
player, cable box, etc), would get sent to a soundbar or Home Theater.
If your TV has ARC already, you’ll just need to get a
soundbar, HTIB, or A/V receiver that also has ARC.
HDMI cables needed:
An Audio Return Channel-enabled TV allows you to send audio over an
already connected HDMI cable. Typically, in order to transfer audio
from your source (TV tuner) to your home theater you would need a
separate audio cable (analog audio or digital optical) going from your
TV to the home theater. With the ARC function, you can send any audio
from your TV back to an ARC enabled home theater receiver and listen to
your TV's audio through the home theater system without having to
connect an optical audio cable.
