Tired of your vibrant projector visuals being let down by tinny, built-in speaker sound? You’ve invested in a big-screen experience, so why settle for less when it comes to audio? Many users find themselves wondering, “How do I get the audio from Roku to my projector?” The truth is, directly routing Roku audio through a projector is often not the primary goal; instead, the aim is to get that rich Roku sound to your external audio system while your projector handles the visuals. This comprehensive guide will walk you through the most effective methods, ensuring your home theater setup delivers both stunning picture and immersive sound.
Understanding the Connection: Roku, Projector, and Audio
Before diving into the solutions, it’s crucial to understand the typical signal flow. Your Roku device (whether a stick, box, or integrated into your TV) outputs both video and audio signals. Your projector is designed to receive and display the video signal. However, most projectors have basic, often underpowered, built-in speakers. To achieve true home theater audio, you’ll need to bypass the projector’s internal audio capabilities and send the sound directly to a more robust audio system. This could be a soundbar, a home theater receiver with surround sound speakers, or even a pair of powered bookshelf speakers.
Method 1: HDMI – The Universal Connector
HDMI (High-Definition Multimedia Interface) is the backbone of modern home entertainment. It carries both uncompressed digital video and digital audio signals simultaneously. This makes it the most common and often the simplest way to connect your Roku to your display and audio system.
HDMI Passthrough with Your Audio Receiver
If you have an audio-video receiver (AVR) or a soundbar with HDMI inputs, this is your ideal scenario.
- Connect Roku to AVR/Soundbar: Plug one end of an HDMI cable into the HDMI output port on your Roku device. Connect the other end to an available HDMI input port on your AVR or soundbar.
- Connect AVR/Soundbar to Projector: Now, connect your AVR or soundbar to your projector. Most AVRs and soundbars have an HDMI output port, often labeled “HDMI Out,” “ARC” (Audio Return Channel), or “eARC” (enhanced Audio Return Channel). Connect this output port to the HDMI input port on your projector using another HDMI cable.
- Configure Inputs:
- On your AVR or soundbar, select the HDMI input port that your Roku is connected to. You should see the Roku interface on your projector screen.
- On your projector, ensure it’s set to receive the input from your AVR or soundbar (likely the HDMI port you connected it to).
Benefits of this method: This setup allows your AVR or soundbar to process the audio signal from the Roku, delivering it to your connected speakers with optimal quality. The video signal is then “passed through” the AVR/soundbar to the projector. This is the cleanest and most direct way to achieve high-quality audio.
Important Considerations:
* HDMI ARC/eARC: If both your projector and your AVR/soundbar support HDMI ARC or eARC, you can potentially simplify the cabling. With ARC, your projector can send audio back to the AVR/soundbar over the same HDMI cable that’s sending video. This is particularly useful if your Roku is connected directly to the projector and you want the projector’s internal audio (if any) or audio from other connected devices to go to your sound system. However, for routing Roku audio to your sound system, the passthrough method described above is generally more direct and reliable.
* Cable Quality: Ensure you are using good quality HDMI cables, especially for 4K or HDR content, to avoid signal degradation.
HDMI Splitter (Use with Caution)
In some niche scenarios, you might consider an HDMI splitter if your AVR or soundbar lacks sufficient HDMI inputs, and you absolutely cannot add a switch. An HDMI splitter takes one HDMI source and outputs it to multiple displays or destinations.
- Connect Roku to Splitter: Connect your Roku to the input port of the HDMI splitter.
- Connect Splitter to Projector: Connect one output port of the splitter to the HDMI input on your projector.
- Connect Splitter to Audio System: Connect the other output port of the splitter to an HDMI input on your AVR or soundbar.
- Configure and Power: Ensure the splitter is powered if required. Select the correct HDMI input on both your projector and your audio system.
Caveats with Splitters: HDMI splitters are not always straightforward. Some splitters may not support HDCP (High-bandwidth Digital Content Protection) properly, which can lead to black screens or error messages on some content. Furthermore, the quality of the splitter can significantly impact signal integrity. Active splitters with signal boosting are generally preferred over passive ones. For the purpose of routing Roku audio to a separate sound system, this method is generally considered less ideal than direct passthrough via an AVR. It’s more for mirroring a signal to multiple displays.
Method 2: Optical Audio (Toslink) – A Dedicated Audio Path
If your Roku device has an optical audio output (often labeled “Digital Audio Out” or “Toslink”), and your projector or audio system has a corresponding input, this is another excellent option. This method separates the audio signal entirely from the video signal.
Connecting Roku via Optical to Your Sound System
- Connect Roku to Projector (HDMI): Connect your Roku to your projector using an HDMI cable for the video signal.
- Connect Roku to Audio System (Optical): Connect one end of an optical audio cable (Toslink cable) to the optical audio output port on your Roku device. Connect the other end to the optical audio input port on your AVR, soundbar, or powered speakers.
- Configure Audio Output on Roku:
- On your Roku device, navigate to Settings.
- Go to Audio & Display.
- Select Audio Output.
- Choose “Optical.” You might have options for stereo or surround sound depending on your Roku model and audio setup.
- Configure Audio Input on Audio System:
- On your AVR or soundbar, select the optical input that your Roku is connected to.
- Configure Projector Display:
- Ensure your projector is set to the correct HDMI input that your Roku is connected to.
Benefits of this method: Optical audio is excellent for transmitting digital audio signals, including surround sound formats like Dolby Digital. It provides a clean, noise-free audio path. This is a great alternative if your AVR/soundbar lacks enough HDMI inputs or if you prefer a dedicated audio cable.
Important Considerations:
* Cable Protection: The optical cable connector is fragile. Ensure you remove the protective caps before inserting them.
* Audio Format: Be mindful of the audio formats your Roku and audio system support over optical. While it commonly supports stereo and Dolby Digital, it might not support newer, more advanced formats like Dolby Atmos or DTS:X in the same way HDMI can.
Method 3: Analog Audio (RCA) – For Older Systems
Some older Roku models or projectors might have analog audio outputs (red and white RCA jacks). This method is generally the lowest fidelity compared to HDMI or optical but can be a lifesaver if you’re working with vintage equipment.
Connecting Roku via RCA to Your Sound System
- Connect Roku to Projector (HDMI): Connect your Roku to your projector using an HDMI cable for the video signal.
- Connect Roku to Audio System (RCA): Connect a set of RCA audio cables (red and white) to the analog audio output ports on your Roku device. Connect the other ends to the corresponding red and white RCA input ports on your AVR, soundbar, or powered speakers.
- Configure Audio Output on Roku:
- On your Roku device, navigate to Settings > Audio & Display > Audio Output.
- Select “Stereo” or “Analog” if these options are available and appropriate for your setup.
- Configure Audio Input on Audio System:
- On your AVR or soundbar, select the RCA input that your Roku is connected to.
- Configure Projector Display:
- Ensure your projector is set to the correct HDMI input.
Benefits of this method: It allows you to get audio to older audio systems that lack digital inputs.
Limitations: Analog audio is susceptible to interference and noise, and it typically only supports stereo sound, not surround sound. The quality will be noticeably lower than digital methods.
Method 4: Bluetooth – Wireless Convenience
Many modern Roku streaming devices, especially Roku Streambars and certain Roku TVs, offer Bluetooth connectivity. This allows you to wirelessly stream audio to Bluetooth-enabled speakers or headphones.
Connecting Roku via Bluetooth
- Enable Bluetooth on Roku:
- On your Roku device, navigate to Settings.
- Go to Remotes & Devices.
- Select Bluetooth.
- Choose “Pair Bluetooth device.”
- Enable Pairing Mode on Your Audio Device: Put your Bluetooth speaker, soundbar, or headphones into pairing mode. Consult your audio device’s manual for instructions.
- Select and Pair: On your Roku, you should see a list of available Bluetooth devices. Select your audio device from the list and follow any on-screen prompts to complete the pairing.
- Configure Audio Output: Once paired, the Roku should automatically attempt to send audio to the Bluetooth device. You may need to go back to Settings > Audio & Display > Audio Output and select your Bluetooth device if it’s not the default.
- Connect Roku to Projector: Connect your Roku to your projector using HDMI for the video signal.
Benefits of this method: Wireless convenience, no extra cables. Great for connecting portable Bluetooth speakers or headphones for private listening.
Limitations: Bluetooth can sometimes introduce a slight audio delay (latency), which can be noticeable during fast-action movies or gaming. Audio quality might also be slightly compressed compared to wired digital connections. Ensure your Bluetooth audio device is also relatively close to your Roku for a stable connection.

By understanding these methods and their nuances, you can effectively route your Roku’s audio to your projector’s sound system, transforming your viewing experience from merely visual to truly cinematic. Choose the method that best suits your existing equipment and desired audio quality, and get ready to immerse yourself in a world of captivating visuals and powerful sound.
Why can’t I hear sound from my projector when my Roku is connected?
This common issue usually stems from incorrect audio output settings on either your Roku device or your projector. Your Roku might be set to output audio in a format that your projector doesn’t support, or the projector might be expecting audio through a different input. It’s also possible that the volume on either device, or on any intermediary audio equipment, is simply turned down or muted.
The first step is to verify your Roku’s audio settings. Navigate to Settings > Display & sound > Audio. Experiment with different audio output modes like “Auto,” “Stereo,” or “Dolby Digital Plus.” Simultaneously, check your projector’s audio input settings to ensure it’s configured to receive audio from the correct HDMI port or other connection you’re using. Don’t forget to check the physical volume controls on both devices.
What are the common connection methods for getting Roku audio to a projector?
The most prevalent and straightforward method is using an HDMI cable. If your Roku device has an HDMI output and your projector has an HDMI input, this is the ideal scenario as HDMI carries both high-definition video and digital audio signals simultaneously, simplifying the setup considerably and offering the best audio quality.
For older projectors or specific setups, you might encounter situations where direct HDMI is not an option. In such cases, you might need adapters or alternative audio extraction methods. For example, if your projector only has analog audio inputs (like RCA or 3.5mm), you would need an HDMI audio extractor to pull the audio signal from the HDMI cable before it reaches the projector, and then connect the extracted audio to the projector via the appropriate analog cable.
How do I adjust the audio output settings on my Roku device?
To access and modify your Roku’s audio output settings, you’ll need to navigate through the device’s main menu. Typically, this involves pressing the Home button on your Roku remote, then selecting “Settings” from the on-screen menu. Within the Settings menu, look for an option labeled “Display & sound” or a similar variation.
Once you’ve located the “Display & sound” section, find the “Audio” submenu. Here, you’ll see various options to control how your Roku outputs audio. Common choices include “Auto,” which allows the Roku to automatically detect and use the best audio format supported by your connected display or sound system. You might also find specific options like “Stereo” or “Dolby Digital Plus,” which you can select if you want to force a particular audio format or if you’re troubleshooting compatibility issues.
What if my projector only has analog audio inputs?
If your projector lacks HDMI ports and only offers analog audio inputs such as RCA (red and white) or a 3.5mm headphone jack, you’ll need a way to extract the digital audio signal from your Roku’s HDMI output. This is where an HDMI audio extractor comes into play.
An HDMI audio extractor is a small device that connects between your Roku and your projector. It receives the HDMI signal, passes the video through to the projector (usually via another HDMI cable), and simultaneously separates the audio. The extracted audio is then output through dedicated analog ports (like RCA or 3.5mm) on the extractor, which you can then connect to your projector’s corresponding audio inputs using standard audio cables.
Can I connect my Roku to a soundbar or AV receiver instead of directly to the projector?
Absolutely. Connecting your Roku to a soundbar or AV receiver is often the preferred method for achieving superior audio quality, especially if your projector’s built-in speakers are not very robust. This setup allows you to leverage dedicated audio equipment designed for immersive sound experiences.
In this scenario, you would connect your Roku device directly to an HDMI input on your soundbar or AV receiver. The soundbar or receiver will then process the audio signal and output it through its own speakers. For the video, you would typically connect the HDMI output of the soundbar or receiver to the HDMI input of your projector, ensuring that both audio and video are routed correctly for a complete cinematic experience.
What troubleshooting steps can I take if I’m still not getting sound?
If you’ve checked your connections and basic settings and still have no sound, the next step is to systematically test each component. Try a different HDMI cable to rule out a faulty cable. Connect your Roku to a different display device (like a TV) to confirm the Roku itself is outputting audio correctly. Similarly, test your projector with a different audio source to ensure the projector’s audio inputs are functioning.
Beyond hardware, software and configuration issues can persist. Ensure your Roku’s firmware is up to date, as updates often include bug fixes and compatibility improvements. Review the audio settings on both your Roku and your projector again, paying close attention to any advanced audio processing options or specific input assignments that might be misconfigured. Sometimes, a simple power cycle of all connected devices (Roku, projector, soundbar/receiver) can resolve temporary glitches.
Does the type of Roku device affect how I connect the audio?
Yes, the specific model of your Roku device can influence the connection methods available and the ease of setup. Roku offers various streaming players, from basic sticks to higher-end boxes, and they can have different types of audio output capabilities or physical ports.
For instance, Roku Streaming Sticks typically connect directly to an HDMI port on your display or audio device, making them very straightforward. Roku Ultra or Premiere models often have more advanced audio codec support and may offer additional audio-specific ports or settings that can be beneficial for more complex audio setups. Always consult the user manual for your specific Roku model and your projector to understand the intended connection pathways and supported audio formats.
