Understanding How HDMI Carries Audio

Before we talk about splitting, it helps to understand what HDMI does. HDMI stands for High-Definition Multimedia Interface. It carries both video and audio through a single cable. This is one of the biggest reasons HDMI became so popular. You plug in one cable, and you get high-quality picture and sound.

But this convenience also creates a challenge. When you want to send the audio somewhere else, you need to extract it. HDMI audio signals are digital. They use formats like Dolby Digital, DTS, and uncompressed multichannel audio. Your TV, soundbar, or receiver must be able to decode these formats. If it cannot, you may get no sound at all.

Why Do People Want to Split HDMI Audio?

There are many reasons someone might need to separate audio from an HDMI source. Here are the most common ones:

• Upgrading your TV speakers: You want better sound but do not want to replace your TV.
• Home theater setups: You have a separate AV receiver and want all audio routed to it.
• Multi-room audio: You want sound from your cable box or gaming console to play in a different room.
• Recording or streaming: You need to capture HDMI audio separately for editing or broadcasting.
• Using older equipment: Your speakers or amplifier only accept analog or optical inputs.

No matter your reason, there is a method that will work for you. Let us look at the most popular options now.

Method 1: Using an HDMI Audio Extractor

An HDMI audio extractor is the most common and reliable way to split audio from HDMI. This small device sits between your source device and your TV. It takes the combined HDMI signal and separates the audio from the video. The video continues to your TV through one output, and the audio goes to a separate device through another output.

How Does an HDMI Audio Extractor Work?

The extractor receives the full HDMI signal. Inside the device, a chip separates the audio and video streams. The video output goes to your display. The audio output usually goes to one of two places:

• HDMI audio passthrough: Some extractors pass the audio back through another HDMI cable to a receiver.
• Analog or optical output: Many extractors include a 3.5mm headphone jack or an optical (TOSLINK) output. This lets you connect directly to speakers, a soundbar, or an amplifier.

Best HDMI Audio Extractors for Beginners

You do not need to spend a lot of money on an extractor. Here are some popular options:

• Kinivo 550BN: A well-known model with HDMI input, HDMI output, and optical audio output. It supports 4K video and is very easy to set up.
• Fosmon HDMI Audio Extractor: A budget-friendly option with HDMI and analog audio outputs. Great for simple setups.
• UGREEN HDMI Audio Extractor: Supports 4K HDMI and includes both optical and analog outputs. Good for home theater users.

When buying an extractor, make sure it supports the resolution you need. If you watch 4K content, choose a 4K-compatible model. Also check whether it supports the audio formats your devices use.

Method 2: Using HDMI ARC or eARC

If you have a modern TV and a soundbar or AV receiver, HDMI ARC (Audio Return Channel) might be all you need. ARC lets audio travel back from your TV to your sound system through the same HDMI cable. This means you do not need a separate audio cable at all.

What Is HDMI ARC?

HDMI ARC is a feature built into most HDMI cables and modern TVs. It allows your TV to send audio to an external speaker system. You connect your TV and soundbar with an HDMI cable, and the TV automatically sends audio to the soundbar. This works for built-in TV apps, streaming sticks, and even game consoles connected to the TV.

eARC (enhanced Audio Return Channel) is the newer version. It supports higher-quality audio formats like Dolby Atmos and uncompressed 7.1 surround sound. If you have a 2019 or newer TV, it likely supports eARC.

How to Set Up HDMI ARC

Setting up ARC is straightforward. Follow these steps:

1. Connect your TV and soundbar with an HDMI cable. Plug it into the ARC-labeled ports on both devices.
2. Go to your TV settings. Find the HDMI or audio settings section.
3. Enable HDMI ARC or eARC. The exact name varies by TV brand.
4. On your soundbar, select the HDMI ARC input.
5. Play audio on your TV. The sound should now come from your soundbar.

One thing to watch out for: some TVs have an “auto output” setting that controls whether audio goes to the TV speakers or the external system. Make sure this is set correctly. If it is not, you may still hear sound from the TV speakers even with ARC enabled.

Method 3: Using an HDMI Audio Converter

An HDMI audio converter is similar to an extractor but focuses only on converting the audio signal. These devices take HDMI input and output audio in a different format. The most common conversions are HDMI to optical or HDMI to analog (3.5mm).

When Should You Use an HDMI Audio Converter?

Converters are useful when your audio destination does not accept HDMI. For example:

• Older stereo systems: Many older amplifiers only have RCA or 3.5mm inputs. A converter lets you connect HDMI audio to these systems.
• Optical-only soundbars: Some soundbars only have an optical input. An HDMI to optical converter bridges this gap.
• PC setups: If your computer has HDMI output but your speakers only accept 3.5mm, a converter solves the problem.

Popular HDMI audio converters include models from brands like UGREEN, Cable Matters, and Kinivo. Prices range from $15 to $50 depending on features and quality.

Method 4: Software Solutions for PC Users

If you are using a PC or laptop with HDMI output, you have software options too. Windows and macOS both let you manage audio output devices. You can split or route HDMI audio without buying extra hardware.

How to Manage HDMI Audio on Windows

Windows makes it easy to choose which device plays your audio. Here is how:

• Right-click the speaker icon in your taskbar.
• Select “Open Sound settings.”
• Under “Output,” choose your HDMI device from the dropdown menu.
• Your PC audio will now play through the HDMI-connected display.

If you want more advanced control, free software like Voicemeeter or Equalizer APO lets you route audio to multiple outputs at once. This is perfect for streaming setups where you want game audio on HDMI and voice chat on your headset.

How to Manage HDMI Audio on macOS

Mac users can also split HDMI audio easily:

• Go to System Settings and click “Sound.”
• Select the “Output” tab.
• Choose your HDMI display from the list of devices.
• Adjust the volume and balance as needed.

For more advanced routing, apps like BlackHole or Rogue Amoeba’s Audio Hijack let you create virtual audio devices. These tools are powerful but may have a learning curve for beginners.

Troubleshooting Common HDMI Audio Problems

Sometimes splitting HDMI audio does not work right away. Here are the most common issues and how to fix them.

HDMI Audio Not Working

If you have no sound after splitting, try these steps:

• Check that your HDMI cable is fully inserted at both ends.
• Make sure the correct audio output device is selected in your settings.
• Verify that your extractor or converter is powered on.
• Restart both the source device and the display.
• Update the audio drivers on your PC if applicable.

HDMI Audio Delay or Sync Issues

Audio delay is frustrating but common. It usually happens when audio and video travel through different paths. Here is how to fix it:

• Look for an “audio delay” or “lip sync” setting on your TV or receiver.
• Reduce the delay in small increments until audio and video match.
• Use the same type of connection for both audio and video when possible.
• Avoid long cable runs for the audio path, as this can add latency.

HDMI Audio Format Not Supported

Sometimes your TV or soundbar does not support the audio format coming through HDMI. This often happens with Dolby Atmos or DTS:X content. To fix this:

• Go to your source device’s audio settings.
• Change the HDMI audio output format to a compatible one like PCM or stereo.
• Check your soundbar or receiver manual for supported formats.
