What Is Optical Audio and How Does It Work?
Optical audio is a digital audio connection that uses light to send sound from one device to another. The technical name is TOSLINK or SPDIF (Sony/Philips Digital Interface). It uses a small square cable with a red light inside. This light carries audio signals as pulses of light rather than electrical current.
Why Optical Audio Still Matters
Even though HDMI has become the standard for both audio and video, optical audio remains widely used. Many TVs still include an optical output. Soundbars, AV receivers, and older audio equipment often rely on it. The reason is simple. Optical connections are reliable and immune to electrical interference. They deliver clean digital audio without distortion.
Here are some key facts about optical audio:
- It carries uncompressed stereo audio and compressed surround sound formats like Dolby Digital and DTS.
- It does not carry video signals. You always need a separate cable for video.
- Maximum cable length is about 5 meters (16 feet) without signal loss.
- It supports sample rates up to 96 kHz for most consumer devices.
- It is not the same as HDMI audio. HDMI can carry uncompressed multi-channel audio, which optical cannot.
Understanding these basics helps you know what to expect when you connect optical to HDMI. The audio quality will be good, but it may not match the full capabilities of a pure HDMI connection.
Can You Connect Optical To Hdmi Directly?
This is the big question. And the honest answer is no, not directly. You cannot plug an optical cable straight into an HDMI port and expect it to work. The two technologies speak different languages. Optical uses light pulses. HDMI uses digital data packets over a different protocol.
So what do you do? You need a translator. That translator comes in the form of a converter or an audio extractor. These devices take the optical audio signal and convert it into a format that HDMI can carry. They also take the HDMI signal and extract the audio portion if needed.
When You Might Need This Conversion
There are several common situations where optical to HDMI conversion becomes necessary:
- Your TV only has an optical audio output but your soundbar or receiver only has HDMI inputs.
- You are upgrading from an older setup that used optical and want to use modern HDMI equipment.
- You have a streaming device like a Roku or Apple TV that outputs audio via optical on certain models.
- Your home theater receiver has HDMI but your TV only offers optical out.
- You want to simplify your cable runs by carrying both audio and video over a single HDMI cable from the converter to your display.
In each of these cases, a converter or extractor solves the problem. The key is choosing the right device for your specific setup. Not all converters are the same, and some may not support the audio formats you need.
How to Convert Optical Audio to HDMI (Step by Step)
Converting optical audio to HDMI is straightforward once you have the right gear. Follow these steps and you will be listening to great sound in no time.
Step 1: Gather Your Equipment
You will need three things:
- An optical to HDMI converter or an audio extractor with optical input and HDMI output.
- An optical audio cable (TOSLINK) to connect your TV to the converter.
- An HDMI cable to connect the converter to your soundbar, receiver, or display.
Make sure your converter supports the audio format you need. Most modern converters handle Dolby Digital and DTS. If you want Dolby Atmos or uncompressed audio, check the specifications carefully.
Step 2: Connect the Optical Cable
Plug one end of your optical cable into the optical output on your TV. Plug the other end into the optical input on the converter. The connection clicks into place with a gentle push. Make sure the cable is firmly seated for the best signal.
Step 3: Connect the HDMI Cable
Plug one end of your HDMI cable into the converter’s HDMI output. Plug the other end into an available HDMI input on your soundbar, AV receiver, or TV. Use an HDMI input that supports audio input, not just video pass-through.
Step 4: Power the Converter
Most optical to HDMI converters need external power. Plug the included power adapter into the converter and into a wall outlet. Some models draw power through the HDMI cable itself, but this is less common.
Step 5: Set the Audio Output on Your TV
Go to your TV’s audio settings. Change the audio output from internal speakers to optical or external speaker. This tells the TV to send audio through the optical port instead of its own speakers. The exact steps vary by brand, but you will usually find this under Settings > Sound > Audio Output.
Step 6: Test the Connection
Play any audio or video content and listen. If you hear sound through your soundbar or receiver, the setup is working. If not, double-check each connection and make sure the TV is set to output audio via optical.

Best Devices for Optical to HDMI Conversion
Not all converters are created equal. Some are basic and affordable. Others offer advanced features like audio format decoding and pass-through capabilities. Here are some things to look for when shopping for a converter.
What to Look for in a Converter
- Audio format support: Make sure it handles Dolby Digital, DTS, and any other formats your devices use.
- HDMI version compatibility: Look for HDMI 2.0 or higher for 4K video pass-through if you also need video conversion.
- Audio extractor vs. converter: An extractor splits audio from an HDMI input into optical output. A converter does the opposite. Know which direction you need.
- Build quality: Metal housings dissipate heat better and feel more durable than plastic.
- Brand reputation: Stick with well-known brands that offer warranty and customer support.
Popular Optical to HDMI Converters
Here are some converter types that work well for most home setups:
- Generic optical to HDMI adapters: These are affordable and work for basic setups. They typically cost between $15 and $40.
- Audio extractors with optical output: These do the reverse job. They take HDMI audio and convert it to optical. Great if your TV has HDMI but your audio system only has optical.
- All-in-one HDMI switchers with optical: These let you switch between multiple HDMI sources and also provide optical audio output. They cost more but offer more flexibility.
When choosing a device, always check user reviews. A converter that works well with one TV may not work with another due to differences in how manufacturers implement the optical audio output.
Common Problems and How to Fix Them
Even with the right equipment, you might run into issues. Here are the most common problems and their solutions.
No Sound After Connecting
This is the most common issue. Start by checking your TV audio settings. Make sure the output is set to optical. Next, verify that the converter is powered on and the HDMI cable is connected to the right input on your sound system. Try unplugging the optical cable and plugging it back in. Sometimes the connection needs a fresh seat.
Audio and Video Are Out of Sync
Audio delay or sync issues can happen with some converters. This is usually caused by processing lag in the converter. If your converter has a delay adjustment setting, try tweaking it. If not, a different converter model may solve the problem.
Only Stereo Audio, No Surround Sound
Optical cables can carry surround sound, but only in compressed formats. If your source sends uncompressed audio over HDMI and the converter only supports compressed formats, you will get stereo sound. Check the converter specifications for surround sound support. Also make sure your TV is set to output surround audio, not just stereo.
Intermittent Audio Dropouts
Loose connections cause dropouts. Make sure all cables are firmly plugged in. If the problem persists, try a different optical cable. Some cheap cables have weak connectors that do not maintain a solid connection. A higher-quality cable often fixes this issue.

Is Optical to HDMI Worth It for Your Setup?
The answer depends on your situation. If you have a TV with only optical output and a modern sound system with only HDMI inputs, then yes. A converter is the most practical solution. It is also worth it if you want to simplify your cable management by using HDMI for both audio and video from a single device.
But if you are building a new setup from scratch, consider using HDMI throughout. HDMI carries both audio and video over a single cable. It supports the latest audio formats including Dolby Atmos and DTS:X. If both your TV and audio equipment have HDMI ports, you may not need optical at all.
Here is a quick comparison to help you decide:
| Feature | Optical Audio | HDMI Audio |
|---|---|---|
| Carries video | No | Yes |
| Max audio channels | 5.1 (compressed) | Up to 7.1 (uncompressed) |
| Supports Dolby Atmos | No | Yes (HDMI eARC) |
| Cable length limit | About 5 meters | Up to 15 meters |
| Interference resistance | High (light-based) | Moderate |
| Common on older TVs | Yes | No (usually) |
| Cost of conversion | Requires converter | Direct connection |
As you can see, HDMI has clear advantages for modern setups. But optical still has a place, especially when dealing with older equipment. The good news is that converters make it easy to bridge the gap between the two technologies.
Quick Tips for the Best Audio Experience
- Use high-quality cables: A good optical cable and a certified HDMI cable make a noticeable difference.
- Keep cables short: Longer runs increase the chance of signal loss, especially with optical.
