7 Tips for Using Lossless Audio With Your Soundbar and TV

Understanding Lossless Audio Requires the Right Connections

Lossless audio delivers uncompressed sound quality that streaming services and Blu-ray players can send directly to your soundbar. However, many people never experience this premium audio because they connect their equipment to the wrong HDMI port on their TV. The difference between the right and wrong connection determines whether you enjoy crystal-clear, detailed sound or compressed audio that loses information during transmission.

Tip 1: Know the Difference Between HDMI ARC and HDMI eARC Ports

Your TV likely has multiple HDMI ports, but they are not all equal. Standard HDMI ARC ports support only about 3 Mbps of bandwidth, which works fine for compressed audio formats. HDMI eARC ports, by contrast, deliver up to 37 to 38 Mbps of bandwidth. This extra capacity is essential for sending uncompressed audio formats like Dolby Atmos and DTS:X to your soundbar. Most televisions include only a single HDMI eARC port, so identifying it before connecting your equipment matters significantly.

Tip 2: Always Connect Your Soundbar to the Correct Port

The most common mistake consumers make is plugging their soundbar into the first available HDMI port without checking whether it supports eARC. If your soundbar has only an HDMI output port and your TV provides built-in streaming apps, you must connect the soundbar to an HDMI eARC port to access lossless audio. Many budget and mid-range soundbars lack HDMI input ports, meaning your streaming device connects directly to the TV, making eARC connectivity non-negotiable for quality sound playback.

Tip 3: Upgrade to Premium Soundbars That Support HDMI In and Out

Higher-end soundbars often include both HDMI input and output ports. This setup allows you to connect your streaming device directly to the soundbar, which then passes video to your TV. With this configuration, you bypass the TV’s HDMI routing entirely, so whether your TV has eARC becomes less critical. If you are planning a soundbar upgrade and want maximum flexibility, look for models that offer this dual-port design. Blu-ray players worth buying under two hundred dollars often require this type of setup for optimal lossless audio delivery.

Tip 4: Use Ultra High Speed HDMI Cables, Not Standard Versions

Even if your TV has an HDMI eARC port, using an old or inadequate cable can prevent lossless audio from working properly. Regular HDMI 2.0 cables, even those rated for 18 Gbps, may not fully support uncompressed audio depending on cable construction and length. You should invest in an Ultra High Speed HDMI cable, which officially supports 48 Gbps of bandwidth. This specification guarantees true capability for lossless audio and video formats. Avoid cables simply labeled HDMI 2.1, since this label does not guarantee proper implementation or adequate bandwidth support.

Tip 5: Understand When Standard ARC Is Sufficient

If your sound system is modest and you rely solely on your TV’s built-in apps for streaming movies and shows, standard HDMI ARC connectivity may be adequate. Most streaming services compress their audio into Dolby Digital Plus format, which functions well over basic ARC bandwidth. However, the moment you add a 4K Blu-ray player, media server, or external streaming device to your setup, lossless audio capabilities become important for premium sound quality.

Tip 6: Build Your Home Media Server With eARC in Mind

An increasing number of consumers are creating personal media servers to store and stream their own content at home. If you plan to build such a system, ensure your TV has an HDMI eARC port. This setup allows you to enjoy lossless audio and video formats stored on your media server, delivering theater-quality sound in your living room. The best wired over-ear headphones for every budget can complement your setup for personal listening, though a quality soundbar remains essential for room-filling performance.

Tip 7: Check Your TV’s Specifications Before Purchasing

Before buying a new television, verify that it includes at least one HDMI eARC port in the specification sheet. Some budget and lower mid-range models skip this feature entirely, restricting your audio options. As of 2026, HDMI eARC should be considered a standard feature rather than a luxury addition. Manufacturers that omit this port limit your ability to enjoy modern lossless audio formats and future-proof your entertainment setup. Always confirm eARC availability, especially if you anticipate expanding your home theater system later.

Conclusion

Enjoying lossless audio through your soundbar requires attention to three critical elements: the correct HDMI port on your TV, the right type of HDMI cable, and an understanding of your specific equipment configuration. By implementing these seven tips, you can ensure that your investment in quality audio equipment delivers the uncompressed, detailed sound it was designed to provide. Whether you own a premium soundbar or are planning an upgrade, proper connectivity transforms your listening experience significantly.
