The good news is that connecting your Onn soundbar to your TV without HDMI is entirely possible, and often quite straightforward. This comprehensive guide will walk you through the various methods, ensuring you can enjoy richer, more dynamic audio without a hitch.
Understanding Your Connection Options
Before diving into the connection process, it’s crucial to understand the different audio output and input options available on your TV and soundbar. While HDMI is the modern standard for digital audio and video transmission, older TVs and some budget models rely on analog connections. Your Onn soundbar, depending on its specific model, will likely support one or more of these alternative connection types.
The Essential Connection Types (Beyond HDMI)
Let’s explore the most common ways to connect your Onn soundbar when HDMI isn’t an option:
Optical Audio (Toslink) Connection
The optical audio connection, often referred to as Toslink, is a highly recommended alternative to HDMI when digital audio quality is a priority. This method uses a fiber optic cable to transmit audio signals.
What You’ll Need:
- An Onn soundbar with an optical audio input.
- A TV with an optical audio output (usually labeled “Optical Out,” “Digital Audio Out,” or with a distinctive square port often covered by a flap).
- An optical audio cable (Toslink cable). These are readily available and relatively inexpensive.
Step-by-Step Connection Process:
- Identify the Ports: Locate the optical audio output port on your TV and the corresponding optical audio input port on your Onn soundbar. The optical port is typically square-ish and often has a small flap or cover.
- Prepare the Cable: Remove the protective plastic caps from both ends of your optical audio cable. It’s vital to ensure these caps are removed, as they will prevent the light signal from transmitting.
- Connect the Cable: Gently insert one end of the optical cable into the TV’s optical output port and the other end into the soundbar’s optical input port. The connectors are usually keyed, meaning they will only fit one way, preventing incorrect insertion. You should feel a slight click when the cable is securely seated.
- Power On and Select Input: Turn on both your TV and your Onn soundbar. Using your TV remote, navigate to the audio settings or input/source menu and select “Optical” or “Digital Audio” as your audio output. On your Onn soundbar remote, select the “Optical” input source. You may need to consult your Onn soundbar’s manual for the exact button or menu option to switch inputs.
Benefits of Optical Connection:
- Digital Signal: Transmits uncompressed digital audio, offering excellent sound quality, superior to analog connections.
- Immune to Electrical Interference: Unlike analog cables, optical cables are not susceptible to electrical hum or interference.
- Wide Compatibility: Many TVs and soundbars, even those without HDMI, feature optical ports.
3.5mm Auxiliary (AUX) Connection
The 3.5mm AUX connection is perhaps the most ubiquitous audio connection method. You’ve likely seen these round ports on smartphones, MP3 players, and older audio equipment. Many Onn soundbars and TVs will feature this port.
What You’ll Need:
- An Onn soundbar with a 3.5mm AUX input.
- A TV with a headphone output or an audio output port that uses a 3.5mm jack (often labeled “Headphone Out” or “Audio Out”).
- A 3.5mm male-to-male audio cable.
Step-by-Step Connection Process:
- Locate the Ports: Find the headphone jack or audio output port on your TV and the AUX input port on your Onn soundbar. Both will be circular with a small hole.
- Connect the Cable: Plug one end of the 3.5mm audio cable into your TV’s headphone or audio output port. Then, plug the other end into the AUX input port on your Onn soundbar.
- Power On and Select Input: Power on both devices. On your TV, you may need to go into the audio settings and ensure that the audio output is set to “Headphones” or “External Speakers.” This often automatically deactivates the TV’s internal speakers. On your Onn soundbar, select the “AUX” or “Line In” input using its remote.
Important Considerations for AUX Connection:
- Volume Control: The volume on your TV’s headphone output might control the signal sent to the soundbar. You might need to adjust the volume on both the TV and the soundbar to achieve the desired listening level. It’s often best to set the TV’s volume to a moderate level (e.g., 50-75%) and then use the soundbar’s remote to control the final volume.
- Sound Quality: While convenient, the AUX connection carries an analog signal, which can be more susceptible to electrical interference and may not deliver the same pristine audio fidelity as an optical connection.
RCA Stereo Audio Connection
RCA connectors are the classic red and white analog audio cables. Many older TVs and some modern ones still include these ports for audio output.
What You’ll Need:
- An Onn soundbar with RCA stereo audio inputs (usually red and white female ports).
- A TV with RCA stereo audio outputs (usually red and white male ports labeled “Audio Out”).
- An RCA stereo audio cable (red and white male connectors on both ends). Some soundbars may come with these cables.
Step-by-Step Connection Process:
- Identify the Ports: Locate the red and white audio output ports on your TV, typically labeled “Audio Out.” On your Onn soundbar, find the corresponding red and white audio input ports.
- Connect the Cables: Match the colors: plug the red RCA cable into the red output port on the TV and the red input port on the soundbar. Similarly, plug the white RCA cable into the white output port on the TV and the white input port on the soundbar.
- Power On and Select Input: Turn on both the TV and the Onn soundbar. Use your TV’s audio settings to ensure the audio is directed to the RCA outputs. On your Onn soundbar, select the “RCA” or “Line In” input option.
Tips for RCA Connection:
- Ensure a Secure Fit: Make sure the RCA connectors are firmly seated in their ports. A loose connection can result in crackling or no sound at all.
- Analog Limitations: As an analog connection, RCA can be prone to interference, potentially affecting sound quality.
Troubleshooting Common Issues
Even with the right connections, you might encounter a few hiccups. Here are some common problems and their solutions:
No Sound at All

What are the primary alternative connection methods to HDMI for an Onn soundbar?
The most common and widely supported alternative connection method for your Onn soundbar is through an optical audio cable, also known as a TOSLINK cable. This digital connection transmits audio signals directly from your TV to the soundbar, offering a significant improvement in sound quality over analog connections. Another viable option is the 3.5mm auxiliary (AUX) cable, which is a more universal analog connection found on most modern televisions and soundbars.
These alternative methods are particularly useful if your TV lacks an HDMI ARC (Audio Return Channel) port or if all your HDMI ports are already occupied. While HDMI ARC offers convenience and sometimes CEC control, optical and AUX connections provide a straightforward and reliable way to get superior sound from your Onn soundbar when HDMI isn’t feasible.
How do I connect my Onn soundbar using an optical audio cable?
First, locate the optical audio output port on your TV. It’s usually a small, rectangular port with a protective flap, often labeled “Optical Out” or “Digital Audio Out.” Simultaneously, find the corresponding optical audio input port on your Onn soundbar, typically labeled “Optical In” or “Digital In.” Ensure both ends of the optical cable are free of any plastic protective covers.
Carefully insert one end of the optical cable into your TV’s optical output port and the other end into your soundbar’s optical input port. You should feel a slight click as it seats properly. Once connected, you’ll need to go into your TV’s audio settings and select “Optical” or “Digital Audio Out” as the audio output source. Finally, switch your Onn soundbar to its optical input mode, usually by pressing a button on the remote or the soundbar itself labeled “Optical.”
What is an AUX cable and how do I use it to connect my Onn soundbar?
An AUX cable, also known as a 3.5mm stereo audio cable, is a common analog audio connection. It features a 3.5mm jack on both ends, resembling a headphone plug. To connect your Onn soundbar using this method, you’ll need to find the 3.5mm audio output port on your TV. This port is often marked with “Audio Out” or a headphone symbol. Locate the 3.5mm auxiliary input port on your Onn soundbar, usually labeled “AUX In” or “Audio In.”
Plug one end of the 3.5mm AUX cable into your TV’s audio output port and the other end into your Onn soundbar’s AUX input port. After establishing the physical connection, navigate to your TV’s audio settings and select “Headphone” or “Audio Out” as the audio output device. Then, select the AUX input mode on your Onn soundbar using its remote or buttons.
Will I lose any sound quality when using optical or AUX instead of HDMI?
When comparing optical and HDMI ARC, the difference in sound quality for standard stereo audio is often negligible to the average listener. Optical cables transmit digital audio signals, which are generally uncompressed for stereo sound, delivering a clear and robust audio experience. However, HDMI ARC is capable of transmitting higher bandwidth formats like Dolby Atmos or DTS:X, which optical cables cannot.
Using an AUX cable is an analog connection, and while it provides a significant upgrade over your TV’s built-in speakers, it is generally considered to have slightly lower fidelity compared to optical or HDMI, especially for complex audio. The quality of the AUX cable itself can also play a role in the overall sound reproduction.
Are there any specific settings on my TV I need to adjust for these connections?
Yes, it’s crucial to configure your TV’s audio output settings correctly. For optical connections, you will typically need to navigate to your TV’s sound or audio menu and select “Optical,” “Digital Audio Out,” or a similar option as the primary audio output. Some TVs may also offer a choice between PCM and Bitstream for digital output; PCM is generally recommended for wider compatibility.
For AUX connections, you’ll usually need to select “Headphone,” “Audio Out,” or “External Speakers” from your TV’s audio settings. It’s also important to ensure that the TV’s internal speakers are disabled when using an external audio device to prevent sound from both sources playing simultaneously. Always consult your specific TV’s user manual for the exact menu paths and options.
What if my Onn soundbar doesn’t have an optical input?
If your Onn soundbar lacks an optical input port, your primary alternative connection method will be the 3.5mm auxiliary (AUX) cable. Most modern televisions, even those without HDMI ARC, will have a 3.5mm headphone or audio out port. This is a universally compatible analog connection.
In this scenario, the process is straightforward: locate the 3.5mm audio output on your TV and the 3.5mm AUX input on your soundbar. Connect them with a 3.5mm AUX cable, and then select the AUX input source on your soundbar. Remember to adjust your TV’s audio settings to output audio through the headphone or audio out port.
Can I control the Onn soundbar volume with my TV remote using these alternative connections?
Generally, when using optical or AUX connections, you will not be able to control the Onn soundbar’s volume directly with your TV’s remote. This functionality is typically enabled through HDMI ARC with Consumer Electronics Control (CEC) technology, which allows devices connected via HDMI to communicate and control each other. Optical and AUX connections are primarily for audio signal transmission and do not support this command protocol.
Therefore, you will likely need to use the separate remote that came with your Onn soundbar to adjust the volume. Some universal remotes might be programmable to control both your TV and soundbar, but this would require an additional setup process. It’s important to manage your expectations regarding remote control integration when opting for non-HDMI audio connections.
