Many of the biggest upgrades to TV audio come from treating your room, not buying expensive speakers or soundbars. The good news is you don’t need professional acoustic treatments or a big budget to make a noticeable difference.

Simple changes using items you already own — or can pick up inexpensively — can help your TV sound better. Your TV may also have a few overlooked settings that can further improve audio quality.

To help you curate the best space for creating clean, rich sound, I’ve put together a list of simple hacks that don’t necessarily require you to open your wallet. 

Soft materials and surfaces

Sound waves love to bounce off hard surfaces like walls, floors, and ceilings. This can cause annoying echoes, tinny-sounding music and dialogue, and generally muddled audio as sound waves move around the room and collide. Thankfully, you can easily combat this simply by filling the room with your favorite furniture and decorations — preferably made of soft materials.

Cloth, leather, and other fabrics absorb sound, rather than reflect it, helping reduce the number of sound waves bouncing around the room. Couches, rugs, throw pillows, and blankets can all play a vital role in the acoustics of your home theater or living room. Even canvas art on the walls can help absorb sound.

With just a little rearranging in your house or apartment, you can massively improve your TV audio for free.

Sound-deadening curtains and studio foam

If your living room or home theater isn’t the problem, noise from outside your home can seriously affect how your TV sounds. If it has to compete with traffic or loud neighbors, even the most expensive OLED could sound terrible. Sound-deadening curtains are an affordable way to help block at least some of the noise coming from the outside. 

Made from layers of heavy materials, they won’t completely eliminate outside noise, but they’ll at least reduce it to a more manageable level.

Sound treatment options like acoustic foam have become much more affordable. You can pick up packs of foam tiles or a pair of corner bass traps for fairly cheap on sites like Amazon to help create strategic reflection and absorption points in your home theater, for perfectly tailored sound while streaming, watching live sports, or console gaming. 

You often don’t need any special tools for foam installation, just a can of spray adhesive, so you can sound-treat your room in a few minutes.

Built-in calibration settings

Many new smart TVs let you set up specific sound configurations for wall mounting and for use with a TV stand. Since many TVs are built with rear- and downward-firing speakers, it’s important to tell the screen which ones to prioritize while producing sound. 

With the wall-mount sound mode, the rear speakers get a volume boost for more powerful sound reflection off the wall behind the TV. In stand mode, the downward-firing speakers are boosted to reflect sound from the table or shelf surface.

For Fire TV

  • Settings > Display & Sounds > AV Sync Tuning

This test calibrates the visual and audio syncing of wall-mounted Amazon Fire TVs, helping reduce latency issues caused by reflecting sound.

For Hisense

  • Settings > Sound > Sound Mode Settings > Wall Mount setup

For LG

  • Settings > Sounds > Additional Settings > Installation Type: WALL MOUNT

For Samsung

  • Settings > Sound Settings > SpaceFit ON

OR

  • Settings > Sound > Expert settings > Auto Volume ON > Optimized Mode ON

If your Samsung TV features adaptive audio, SpaceFit activates the built-in sensor that automatically monitors ambient sound and adjusts settings and volume for the best listening experience.

For Sony

  • Settings > Display & Sound > Sound > Acoustic Auto Calibration ON

If your Sony TV uses the Acoustic Surface Audio+ system, toggling on the auto calibration system will activate the built-in sensors to monitor ambient noise levels and how well sound reflects from surfaces behind or beneath the TV.

For TCL

  • Settings > Display & Sounds > Audio > Mount Configuration: Wall

For Roku TV

  • Settings > Audio > Optimize for wall-mounted TV

TL;DR

India debates sovereign AI after the US forced Anthropic to kill Fable 5, with proposals for a $5B fund and calls to embrace open-source models.

When the US government ordered Anthropic to shut down Fable 5 and Mythos 5 on 12 June, the export control directive was aimed at restricting foreign nationals from accessing America’s most capable AI. In India, Anthropic’s second-largest market, it landed as a warning shot about what happens when your AI infrastructure runs on someone else’s politics.

The suspension cut off Indian developers and enterprises from Claude’s most advanced models overnight. India’s Claude run-rate revenue had doubled since October 2025, and Tata Consultancy Services had announced a partnership just one day earlier, on 11 June, to train 50,000 employees on Claude and build a dedicated Anthropic business unit. That deal is now in limbo.

The timing has turned what was already a simmering debate about AI sovereignty into a full strategic reckoning. Proposals that sounded ambitious a week ago now sound urgent.

Mohandas Pai, former Infosys CFO and one of India’s most prominent tech investors, has called for a ₹50,000 crore (roughly $5 billion) annual sovereign AI fund. He has also proposed a ₹2 lakh crore (approximately $21 billion) credit guarantee to finance cloud infrastructure, hardware procurement, and semiconductor development. The figures dwarf the government’s existing commitment.

India approved its IndiaAI Mission in March 2024 with a budget of ₹10,372 crore, approximately $1.25 billion. The programme has deployed around 38,000 GPUs so far. Pai’s proposal would quadruple annual spending and add a credit backstop an order of magnitude larger.

Sridhar Vembu, the founder of Zoho, has gone further. He argued that India should embrace smaller and open-source models, including Chinese ones, rather than depend on American frontier systems that can be switched off by executive order. “Technology is the ultimate weapon,” Vembu said. “Globalization is dead and Bharat must find her own way ahead.

The argument has teeth because the suspension demonstrated exactly the vulnerability Vembu is describing. Amazon’s CEO reportedly triggered the government crackdown by telling Treasury Secretary Scott Bessent that researchers had used Fable 5 to obtain information that could be used in cyberattacks. Anthropic called the action disproportionate, but compliance was immediate and global.

Policy expert Prasanto Roy put it bluntly: “American AI models are bound to American geopolitics.” For Indian enterprises that had built workflows around Claude, the lesson was that access to frontier AI is a privilege that can be revoked without notice, without consultation, and without regard for the commercial relationships it disrupts.

The Indian startup ecosystem is already adapting. Sarvam, a Bengaluru-based AI company, released 30-billion and 105-billion parameter open-source models at the India AI Impact Summit in 2026. Krutrim, founded by Ola’s Bhavish Aggarwal, has pivoted from building foundational models to providing cloud and AI infrastructure services, reporting ₹3 billion in revenue for fiscal year 2026.

Neither company is close to matching the capabilities of Fable 5 or Mythos 5. But the argument for sovereign AI was never about matching frontier performance immediately. It is about ensuring that the floor does not fall out when Washington makes a unilateral decision about who gets to use which models.

Aakrit Vaish, founder of the AI startup Activate, said the suspension “completely changes things” for the sovereign AI debate. Vijay Rayapati, CEO of Atomicwork, raised concerns about what the precedent means for Indian companies with multi-country teams that depend on American AI providers. If the US can shut off model access to enforce export controls, any country that relies on American AI is one policy decision away from disruption.

Not everyone agrees that India needs to build its own frontier models. Hemant Mohapatra, a partner at Lightspeed Venture Partners, argued that talent and compute access matter more than capital for building competitive AI. India has the engineering workforce, but the compute gap is significant, and closing it requires either massive domestic investment or continued access to foreign cloud infrastructure.

Anthropic opened a Bengaluru office as part of its India expansion, and the TCS partnership was designed to be a cornerstone of its enterprise strategy in the country. Whether those plans survive the suspension intact depends on how quickly Anthropic can restore access and whether Indian enterprises still trust a provider whose most capable models can vanish overnight.

The broader pattern is unmistakable. The US has spent four years tightening controls on AI technology, from chip export restrictions to model-level interventions. Each escalation pushes more countries toward the conclusion that dependence on American AI infrastructure carries political risk. India, with its 1.4 billion people and rapidly growing technology sector, is now asking whether it can afford that risk, and what it would cost to eliminate it.

The Opendoor layoffs in June 2026, which shut the company’s India office and affected roughly 250 employees, added another dimension. CEO Kaz Nejatian cited AI-native teams as the reason, suggesting that some US companies are using AI to reduce their reliance on Indian engineering talent at the same time that India is debating its reliance on American AI. The relationship is becoming less complementary and more competitive.

For now, the sovereign AI proposals remain proposals. Pai’s fund has no legislative vehicle, Vembu’s call for open-source adoption has no coordinated policy framework, and the IndiaAI Mission’s GPU deployment is still in early stages.

But the Anthropic suspension has done something that years of policy papers and conference speeches could not: it has given the sovereign AI movement a concrete, recent, and viscerally felt example of why dependence on foreign AI is a strategic liability. The debate is no longer theoretical.
