Understanding the Core of Soundbar Connectivity

Before we directly address the Sonos-specifics, it’s essential to grasp the fundamental ways soundbars connect to televisions. Historically, analog audio cables like RCA or optical cables were the primary methods. However, the advent of digital audio transmission, particularly through HDMI, revolutionized this.

HDMI, or High-Definition Multimedia Interface, is more than just a way to transmit audio. It’s a unified digital connection capable of carrying both high-definition video and multi-channel audio signals simultaneously. This integration offers several advantages:

Simplicity: A single cable handles both video and audio, reducing clutter.
Superior Audio Quality: HDMI can transmit uncompressed digital audio formats like Dolby Atmos and DTS:X, delivering a richer and more immersive sound experience compared to older analog or compressed digital formats.
Enhanced Features: HDMI supports technologies like Audio Return Channel (ARC) and Enhanced Audio Return Channel (eARC). These are crucial for seamless integration between your TV and soundbar. ARC allows audio to be sent back from the TV to the soundbar using the same HDMI cable that sends video to the TV. eARC, an evolution of ARC, offers higher bandwidth, enabling the transmission of more advanced audio codecs like Dolby TrueHD and DTS-HD Master Audio, which are often found in high-fidelity Blu-rays and streaming services.
CEC (Consumer Electronics Control): This HDMI feature allows devices connected via HDMI to control each other. For instance, your TV remote can often control the volume of your soundbar when connected via HDMI ARC/eARC.

Does the Sonos Arc Require HDMI?

Yes, the Sonos Arc fundamentally requires an HDMI connection to function as intended and to unlock its full potential, particularly its Dolby Atmos capabilities.

The Sonos Arc features a single HDMI eARC port. This is not a mere convenience; it’s the primary gateway for the high-bandwidth audio data necessary to deliver its advanced sound features.

eARC for Dolby Atmos: To experience Dolby Atmos, which is a significant selling point of the Arc, your TV must support HDMI eARC and be connected to the Arc’s HDMI eARC port. This allows the uncompressed Atmos data to flow from the TV to the soundbar. If your TV only supports ARC, the Arc can still receive compressed Atmos signals, but it won’t be the full, lossless experience.
CEC Control: Connecting the Arc via HDMI also enables CEC, allowing your TV remote to control the Arc’s volume and power. This is a highly desirable feature for a streamlined user experience.
Setup and Updates: While the initial setup can often be done through the Sonos app wirelessly, the physical connection for audio playback is via HDMI. Future firmware updates are also managed wirelessly.

Crucially, the Sonos Arc does not have an optical audio input. This means if your TV does not have an HDMI ARC or eARC port, you will not be able to connect the Sonos Arc directly.

Does the Sonos Beam (Gen 2) Require HDMI?

Similar to the Sonos Arc, the Sonos Beam (Gen 2) strongly benefits from and primarily utilizes an HDMI connection, specifically HDMI ARC.

The Beam (Gen 2) also features a single HDMI ARC port. While it can process Dolby Atmos, it does so through virtual surround sound processing and upward-firing drivers. To receive the best possible audio signal, including virtual Dolby Atmos from streaming services, an HDMI ARC connection is essential.

HDMI ARC for Sound and Control: The HDMI ARC port on the Beam (Gen 2) is the primary conduit for audio from your TV. It also facilitates CEC control, allowing your TV remote to manage volume and power.
Optical Adapter: A significant advantage of the Sonos Beam (Gen 2) is that it includes a Sonos Optical Audio Adapter. This adapter plugs into the Beam’s HDMI port and provides an optical audio input. This means that if your TV does not have an HDMI ARC port, you can connect the Beam (Gen 2) to your TV using an optical audio cable. However, it’s important to note the limitations of optical audio.

Limitations of Optical Audio with Beam (Gen 2):

When using the optical adapter, you will be limited to stereo PCM audio or compressed surround sound formats like Dolby Digital.
