How to fix terrible TV speaker sound: 5 settings that actually make a difference

At a glance:

• Sound Mode: Switch from "Standard" to "Theatre," "Movie," or "Cinema" for better bass and immersion
• Dolby Atmos: Disable it on built-in speakers to avoid hollow, unnatural audio
• Auto Volume: Enable for consistent levels or turn off for natural dynamics

When Tanveer's 5-year-old soundbar died unexpectedly, he was forced to rely on his TV's built-in speakers for several days. The experience reminded him why he originally bought a soundbar in the first place—the default audio quality was simply unusable for anything beyond casual YouTube videos. With time on his hands and a new soundbar on the way, he experimented with the TV's audio settings and discovered that a few simple toggles could make the speakers significantly more tolerable.

Most people dismiss TV speakers as beyond help, assuming the hardware limitations are insurmountable. However, the software settings layered on top of those speakers can either mask or amplify their weaknesses. By adjusting key parameters, even modest built-in audio can become more listenable for everyday content.

Sound Mode: Start with the right preset

Every TV includes several audio profiles designed for different types of content. The default is typically "Standard," which aims for neutrality but rarely delivers optimal results for built-in speakers. Tanveer's Hisense TV offered multiple modes including Theatre, Movie, Cinema, Music, Speech, and Sports. Switching to Theatre mode enhanced bass response and created a more immersive soundstage, making it ideal for movie viewing. The exact naming varies by manufacturer—"Movie" or "Cinema" modes serve a similar purpose. For dialogue-heavy content, the Speech mode reduces bass and emphasizes mid-to-high frequencies, while Sports mode boosts crowd noise and commentator clarity.

These presets apply basic equalization and processing tailored to specific content types. While they cannot overcome fundamental hardware limitations, they can significantly improve the listening experience within those constraints. Experimenting with different modes is the quickest way to find a baseline improvement.

Dolby Atmos: Keep it disabled for built-in speakers

Dolby Atmos creates a three-dimensional soundscape that requires specific hardware to execute properly. This includes dedicated multi-channel speakers, up-firing drivers, or physical rear channels. When enabled on systems lacking this hardware, the TV attempts to simulate spatial audio through software processing, often resulting in unnatural or hollow sound. Tanveer had Dolby Atmos enabled on his Hisense TV and noticed the improvement after disabling it.

Some TVs offer Dolby Atmos via software simulation that may provide better results than no spatial audio at all. If the built-in speakers are the only option, testing both enabled and disabled states can reveal which setting produces clearer audio. However, for most built-in speaker setups, disabling Dolby Atmos prevents the system from attempting processing it cannot deliver effectively.

Auto Volume: Balance consistency with dynamics

Auto Volume Control (also labeled as Audio Leveler or Volume Leveler) compresses the difference between quiet and loud audio segments. This prevents jarring transitions when watching movies, where whispers and explosions exist in the same scene, or when commercials interrupt programming. The feature also helps during late-night viewing by maintaining consistent volume levels that won't disturb others in the household.

The trade-off is that Auto Volume flattens the natural soundscape, reducing the dynamic range that gives audio its sense of space and impact. On high-quality sound systems, this compression can make audio feel lifeless. Tanveer chose to keep this feature disabled to preserve the natural audio experience, though he recommends enabling it for regular content consumption.

Dialogue Enhancement: Prioritize speech clarity

Dialogue Boost or Video Enhance (as it's called on some systems) isolates and amplifies vocal tracks while reducing competing background sounds and music. This addresses a common complaint about modern media content, where dialogue is often mixed at lower volumes than action sequences and musical scores. The feature acts as a band-aid for poorly balanced audio mixes in contemporary movies and television shows.

Not all TVs include this setting—Tanveer's Hisense model lacked it, while his Apple TV 4K 3rd generation included an "Enhance Dialogue" option that provided decent results. When available, the feature can make content significantly more intelligible, though it may reduce overall audio quality by suppressing other elements.

Virtual Surround Sound: Expand the soundstage

Virtual Surround Sound processes stereo audio to create the illusion of multiple speaker positions, effectively expanding the soundstage. For built-in speakers, this artificial enhancement can make audio feel fuller and more immersive than the native output. Tanveer recommends enabling this feature when using TV speakers exclusively.

However, when a dedicated soundbar or speaker system is present, virtual surround should be disabled to avoid unnecessary audio processing that can degrade quality. The implementation varies significantly between manufacturers, with some using proprietary formats or Dolby Atmos-based processing. Results depend heavily on the TV's speaker quality—lower-end models may experience distortion rather than improvement.

Mid-range and high-end TVs typically implement virtual surround more effectively, making it worth testing to determine whether the processing improves or detracts from the listening experience. The key is finding the right balance between enhancement and authenticity for your specific setup.

Finding the right combination

Tanveer's experiment revealed that even modest adjustments to audio settings can yield meaningful improvements in TV speaker performance. The exact optimal configuration depends on content type, speaker quality, and personal preference. Testing different combinations of these settings allows users to find their preferred balance between clarity, immersion, and natural sound reproduction.

For those awaiting new audio equipment or working within budget constraints, these software adjustments provide a practical middle ground. While they cannot transform poor hardware into premium audio, they can make the difference between barely tolerable and reasonably acceptable sound quality for everyday viewing.

The process of experimenting with settings also builds familiarity with the TV's audio capabilities, creating a foundation for future upgrades. Understanding how each parameter affects the listening experience proves valuable when eventually investing in dedicated audio equipment.
