When shopping for a television with flexible audio routing, start by examining the available output options. Look for HDMI ARC (Audio Return Channel) and eARC (enhanced Audio Return Channel) capabilities, as they enable two-way audio between the TV and your sound system. Verify that your soundbar or AV receiver supports the same standard, and note whether the TV can send high-bandwidth formats such as Dolby Atmos or DTS:X through these paths. Beyond HDMI, check for optical digital and analog outputs, since some setups rely on older gear or dedicated DACs. A practical setup criterion is to ensure the TV can independently route audio to the external device without forcing you into complex workarounds or firmware workarounds that degrade sound quality.

Beyond raw connectivity, a smart TV should offer intuitive sound settings that persist across power cycles. Favor models with a clear, organized audio menu that lets you designate the preferred audio output per input source. This matters when you switch between streaming apps that may default to TV speakers versus a connected system. Look for configurable lipsync, HDMI passthrough toggles, and the ability to assign different volume controls to the TV and the external audio chain. A robust setup also includes consistent volume levels across devices, so quiet scenes don’t become thunderous wall-rattlers when you switch inputs. If possible, test the interface by following on-screen prompts with your actual soundbar or receiver connected.

The first practical step is to confirm the TV’s HDMI ports align with your soundbar or AV receiver inputs. An HDMI ARC or eARC connection should appear in the spec sheet, and you should verify that the TV supports the corresponding standard for your region. If your equipment already uses an external preamp or processor, ensure the TV can bypass internal processing when needed, so the signal remains unaltered. In addition, review the TV’s firmware update history for audio-related improvements. A device that receives regular, non-disruptive updates is more likely to stay compatible with newer audio formats. When you test, use a trusted source of high-quality audio to judge clarity, timing, and channel separation.

Another essential factor is the ability to route audio to the external device even as you navigate apps at different bitrates. A capable TV should provide per-input passthrough settings so streaming apps don’t force delivery through the TV’s built-in speakers. If your soundbar or receiver uses multi-channel playback, ensure the TV can pass through lossless formats without downmixing. It’s also helpful when the TV supports fixed-volume control for external outputs, allowing you to keep the soundbar’s or receiver’s loudness independent of the TV’s own volume. Finally, confirm whether lip-sync adjustments are available for every input, or at least for those most frequently used, to prevent audio delays that mar the viewing experience.

With the hardware basics in place, explore how the TV handles device discovery and control compatibility. A model that supports CEC (Consumer Electronics Control) can simplify remote operations, letting you power everything on or off with a single command. While CEC is convenient, test whether enabling it introduces unexpected volume or mute behaviors across devices. Some brands implement oversimplified control that causes audio to switch unexpectedly or fail to return to the proper channel when sources change. Favor brands known for stable CEC behavior and reliable pass-through. Documentation that clearly explains how the TV negotiates formats with external gear is a strong indicator of long-term compatibility.

Another practical consideration is how the TV negotiates audio formats via HDMI. Pay attention to whether the TV negotiates Dolby TrueHD, DTS-HD Master Audio, or Dolby Atmos through ARC/eARC, and whether this negotiation is consistent across apps and channels. Some TVs automatically downmix to stereo if the incoming stream doesn’t match the external device, while others pass the signal intact. If your setup relies on precise channel mapping, opt for models with explicit format support and the ability to lock the preferred pass-through mode. It’s also worth checking for a “pass-through” or “raw output” option that bypasses processing entirely, which is invaluable for enthusiasts who demand pristine signal integrity.

Consider the internal audio processor’s impact on passthrough. Some televisions perform aggressive post-processing that can degrade a high-quality external signal, even when you’ve selected passthrough. If you intend to use an external AV receiver to decode audio, the TV should minimize its own ionized processing or at least provide a mode to disable it. The ideal scenario is a disabling path for internal decoding, so the receiver handles bass, surround, and height effects. In practice, this means checking for “ passthrough” modes, “bitstream” selections, and independent volume controls on the TV. You’ll want to avoid menus that quietly re-encode or re-sample audio without your awareness, which can ruin the intended sonic experience.

Finally, consider the practicalities of setup time and ongoing maintenance. A television that supports straightforward firmware updates, a clear set of audio features, and easy toggling between soundbars and receivers makes life simpler. If you anticipate frequent changes to your home theater configuration, prefer a TV with documented, accessible diagnostics for audio paths. Some manufacturers publish detailed troubleshooting guides that address HDMI-ARC/eARC behavior, lip-sync issues, and pass-through stability. While no device is perfect, a model that prioritizes long-term compatibility with third-party audio gear will reduce frustrating reconfigurations. Before purchasing, read user reviews focusing on real-world audio routing experiences and how often firmware updates address reported issues.

When you finally test in-store or at home, simulate common viewing scenarios to verify end-to-end audio routing. Start with a streaming app sending audio to the TV via HDMI and confirm it passes through to your soundbar or receiver without unintended changes in format or volume. Then switch to a game console, a Blu-ray player, and a smart home audio source to confirm consistent behavior. Note whether changing inputs preserves the preferred passthrough settings or requires reconfiguration. If you experience inconsistency, check the audio output configuration for each input and ensure the CEC and HDMI-CEC settings align across devices. A smooth, repeatable experience saves time and reduces the likelihood of buyer’s remorse.

Additionally, consider room acoustics and how much headroom your system provides for dynamic ranges. The best TV-audio paths preserve dynamic nuance, so dialogue remains intelligible while action scenes retain impact. If your room employs dense furnishings or panels that affect reflections, you may benefit from a stronger central channel focus or a well-tuned soundbar with dedicated rear channels. When evaluating, take note of the TV’s baseline noise floor and how it responds to quiet passages through the external system. A well-balanced combination can elevate even modest setups, delivering clear dialogue and immersive ambience without demanding excessive listening volume.

As you compare models, compile a short checklist of must-have features versus nice-to-have enhancements. Prioritize HDMI ARC/eARC compatibility, robust pass-through, independent volume control, and reliable lip-sync adjustments. Document for each candidate how the TV negotiates formats with your specific soundbar or receiver. If possible, request a live demonstration showing at least three different input configurations, confirming that your preferred pass-through path remains stable. Pay attention to the user interface’s ease of use; a confusing menu can negate otherwise solid technical capabilities. A product that offers clear guidance and straightforward controls will empower you to tailor sound to your room and preferences.

In the end, the right television for flexible audio routing is one that harmonizes with your existing soundbar or AV receiver without forcing compromises. Seek a model that delivers consistent pass-through, preserves high-resolution formats, and provides intuitive per-input controls. Ensure your setup supports bidirectional audio with HDMI ARC/eARC and retains stable lip-sync across sources. Don’t underestimate the value of good documentation and responsive firmware updates aimed at audio compatibility. By focusing on these criteria, you’ll choose a TV that remains adaptable to evolving audio gear, future formats, and changing viewing habits, delivering reliable performance for years to come.
