If your TV has no optical output, check HDMI ARC first. It costs nothing when both the TV and soundbar already support it, and it carries more than optical ever could. If ARC isn't there, an HDMI audio extractor is the workable fix for most people, though it usually has to sit between your TV and a source device, not on the TV itself. Bluetooth and analog outputs cover more situations for free, at a real cost in delay or sound quality. And for one specific setup, there is no free fix at all. Here are the five real options, in the order to check them, with what each one costs you.
Check for HDMI ARC First, It Is Probably Already There
Before buying anything, look at the HDMI ports on the back of your TV. One of them, usually the one you'd naturally use for a soundbar or receiver, is often printed with a small "ARC" or "eARC" label, sometimes next to the port number. If your soundbar has an HDMI port of its own, and it's marked the same way, you likely already own the fix.
This is the single most useful five minutes in this whole guide. A lot of readers land here assuming they need to buy an adapter, when the port has been sitting there unused the entire time. Plug a single HDMI cable between the two ARC-labeled ports, switch the TV's audio output setting to HDMI or ARC in the menu, and the soundbar starts receiving sound from every app and input on the TV. No new cable purchase beyond the HDMI cable itself, which most households already have a spare of.
ARC also isn't a downgrade from optical. Optical (Toslink) is a fixed-bandwidth format that was never built to carry the newer surround formats streaming services now use. ARC, and especially eARC on newer gear, can carry formats optical simply cannot. If you're deciding between the two on capability rather than what your TV happens to have, our comparison of optical audio and HDMI ARC and our deeper look at HDMI ARC vs eARC cover exactly what each one gains you.
If you've confirmed neither the TV nor the soundbar has an ARC-labeled port, move to the next option.
Why Optical Disappeared From New TVs
It can feel like a strange downgrade when a brand-new television arrives with fewer audio ports than the one it replaced, but the disappearance of the optical (Toslink) port is a deliberate, industry-wide trend, not a defect. TV panels have gotten thinner every generation, and a full-size Toslink port takes up more internal depth than most manufacturers want to spend on a connector that a single HDMI cable can now replace functionally. Once HDMI ARC, and later eARC, could send audio back out of the TV over a cable that was already there for video, optical became redundant from the manufacturer's point of view, even though it's still very much in use on the soundbar side of millions of living rooms.
That mismatch, a TV built around HDMI-only audio output paired with a soundbar built around optical input, is exactly the gap this guide exists to close. If you've confirmed your soundbar's optical input is fine and the problem is actually no sound reaching it despite the cable being connected, that's a different issue with its own checklist; see no sound from your soundbar over optical for that troubleshooting path. For a plain explanation of what the format is and does, see what optical audio actually is.
HDMI Audio Extractor: What It Does and Where It Has to Sit
An HDMI audio extractor is a small box that takes an HDMI signal in, sends the video on to your TV through one HDMI output, and pulls the audio out through a separate port, typically optical, coaxial, or analog stereo. For a reader whose soundbar only accepts optical, this is the piece of hardware that recreates the optical connection your new TV no longer has.
Here is the caveat that most ranking pages for this problem skip entirely, and it is where readers waste money on the wrong box. An HDMI audio extractor needs an HDMI signal going into it and produces its outputs from that. On most modern televisions, every HDMI port on the TV is an input, not an output; there is nothing on the back of the set for an extractor to plug into and extract from. That means the extractor generally cannot sit between the TV and the soundbar the way you'd assume from the name.
Instead, it sits upstream, between your source device and the TV: a streaming box, a cable or satellite box, or a game console plugs into the extractor's HDMI input, the extractor's HDMI output goes on to the TV as normal, and the extractor's audio output (optical, in this case) goes to the soundbar. Video passes through unchanged; audio gets split off along the way, before it ever reaches the TV.
That placement has a real consequence worth stating plainly. Because the extractor only captures audio from whatever is plugged into its input, it cannot capture audio generated inside the TV itself, meaning the TV's own smart-platform apps (its built-in Netflix or YouTube app, for example) and its live tuner, if it has one. Only the audio from the external device feeding the extractor makes it to the soundbar. If most of your viewing goes through one external streaming box or console anyway, this is a clean, workable fix. If you rely heavily on apps built into the TV itself, an extractor placed upstream of the TV won't reach them, and that limitation is worth knowing before you buy one rather than after.
On cost, an HDMI audio extractor sits above a simple cable but below the price of new equipment, because it's doing real signal conversion rather than just carrying a signal from one plug to another. Extractors are also sold in tiers: basic models pass through standard HD audio formats and stereo or basic surround, while higher tiers add support for passing 4K video without degradation and decoding a wider range of surround formats before sending them out as optical. If your source is a 4K streaming box or console, confirm the extractor is rated to pass 4K through cleanly; a model built for older HD sources can bottleneck the video signal even though the audio extraction itself works fine.
Bluetooth, and the Delay It Brings
If your soundbar has a Bluetooth receiver built in, and a growing number do, some smart TVs can pair directly to it as though the bar were a pair of wireless headphones. This has become a fairly common accessibility and convenience feature on recent Samsung, LG, Sony, and Roku TV models, tucked into the sound or accessibility settings menu rather than the main audio-output menu, so it's worth checking there specifically even if the main settings don't mention it.
Where this option costs nothing, it costs you in timing. Bluetooth handles audio by buffering it in short bursts rather than sending a continuous signal, and that buffering introduces a small but noticeable delay between the picture and the sound. It's usually most obvious on close-up dialogue, where lip movement and voice fall slightly out of step, and it can be more pronounced with live TV or fast-cut content than with a movie. Some TVs include an audio delay or lip-sync adjustment setting that lets you nudge the sound earlier to compensate, and it's worth trying if the gap bothers you, though how well it works depends on the TV and the Bluetooth codec both sides support.
Bluetooth is worth trying specifically when neither device has ARC and you want a genuinely free, cable-free fix, and you can live with a small, constant lag.
Analog and Headphone Outputs
Some TVs that dropped optical kept a 3.5mm headphone jack or a pair of RCA analog audio outputs, often marked simply as "audio out" rather than anything soundbar-specific. If your soundbar has a corresponding analog input, a basic cable (a 3.5mm-to-RCA cable is about as cheap as anything on this list) will get sound flowing.
The catch is that this path carries stereo only. Whatever surround processing your soundbar is capable of, Dolby Digital decoding, virtual surround modes, an Atmos upmixer, none of it has anything to work with over a plain analog stereo signal, because the TV is sending a simple two-channel mix rather than a full surround bitstream. For a soundbar bought specifically for movie or TV surround sound, that's a real downgrade, arguably defeating the reason you bought a soundbar over built-in TV speakers in the first place. It's a legitimate stopgap while you sort out a better connection, not a destination.
Connecting Sources Straight to the Soundbar, and What You Lose
If your soundbar has its own HDMI inputs, and many mid-range and higher bars do, you can plug your streaming box, cable box, or console directly into the soundbar instead of the TV, with the soundbar then passing video on to the TV over its own HDMI output. Audio never has to travel through the TV's limited output options at all, because it never reaches the TV in the first place.
This costs nothing beyond rearranging cables you already own, and it sidesteps every limitation above: no ARC needed, no extractor, no Bluetooth delay, full surround formats intact. The cost shows up in what you lose access to. The TV's own built-in apps and any live tuner still live on the TV, not on the connected source, and none of that audio reaches the soundbar this way, for the same underlying reason an upstream extractor misses it: the sound is generated inside the TV itself, not on a cable running into or out of an external box. If your primary viewing already goes through one or two external devices and you rarely open a TV's own apps, this is a genuinely good permanent answer. If you regularly rely on the smart TV interface itself, you'll be giving up its sound entirely for anything you watch that way.
When There Is Genuinely No Path
There's one specific setup where none of the above works for free, and it's worth naming honestly rather than padding this guide with options that don't apply to it. If your TV has no optical port and no ARC-labeled HDMI port, and your soundbar accepts optical only, with no Bluetooth on either device, there is no free path that carries the TV's own app and tuner audio to that soundbar. Every workaround above either needs ARC, needs a piece of hardware to buy, or only covers audio from an external source device rather than the TV's own built-in sound.
In that situation, the honest options are to buy an HDMI audio extractor and accept that it will only cover the sources plugged into it rather than the TV's built-in apps, or to accept that the built-in apps route through the TV's own speakers while everything plugged into an external box routes through the soundbar. There isn't a third free option hiding in a forum thread; if there were, it would be in this guide.

Frequently Asked Questions
Does every new TV lack an optical port?
No. Some budget and mid-range sets still include one, and manufacturers vary the port selection by model year and region. Check the back and side panels of your specific TV rather than assuming based on the brand alone; ports are usually labeled, and a quick look at the manual or spec sheet will confirm what's there.
Can I convert HDMI ARC to optical if my soundbar only has an optical input?
Yes, that's essentially what an HDMI audio extractor does when placed upstream of your source, and some ARC-specific adapters exist for exactly this pairing. Confirm the adapter or extractor is rated for the audio format your source actually sends, since a model built only for basic stereo or Dolby Digital won't pass a higher-tier surround format cleanly.
Is an HDMI audio extractor the same thing as an HDMI switch?
No. A switch lets multiple HDMI sources share one HDMI input on your TV and does nothing to the audio. An extractor takes one HDMI signal and splits the audio out to a separate port while passing video through unchanged. Some higher-end boxes combine both functions, but they're solving different problems.
Will using Bluetooth from my TV to my soundbar work with every app?
If the TV's own Bluetooth-audio feature is system-level, meaning it routes all sound leaving the TV rather than sound from just one app, it should cover everything the TV plays, including its own built-in apps and tuner. That's actually one of Bluetooth's advantages over an upstream HDMI extractor, which only ever hears one connected source. Check your TV's accessibility or sound settings menu to confirm whether its Bluetooth pairing is system-wide before relying on it.
What if my soundbar has neither optical nor HDMI, only Bluetooth?
Then Bluetooth is your only path regardless of what your TV supports, and the fix is confirming the TV itself can broadcast audio over Bluetooth rather than only receive it from a phone. Most TVs with this feature list it under sound or accessibility settings as "Bluetooth speaker list" or similar, separate from any Bluetooth remote pairing option.
