Sonos has been busy expanding its premium audio lineup, introducing new hardware that pushes the boundaries of spatial audio and multi-room connectivity. From high-end soundbars to updated personal listening gear, the company is focusing on deeper integration within its ecosystem, though these advancements bring new technical considerations for home theater enthusiasts.
Sonos Arc Ultra Users Report Audio Balance Fluctuations
The flagship Sonos Arc Ultra is currently under scrutiny by owners reporting inconsistent volume levels and balance issues. According to user reports on the Sonos community forums, the soundbar exhibits noticeable fluctuations during music and live sports broadcasts. The detail that matters here is the balance between vocal and instrumental tracks, or commentary and crowd noise, which reportedly shifts unexpectedly rather than maintaining an equal level.
One specific case involves an Arc Ultra connected via the eARC port to a five-year-old LG 55-inch Ultra HD TV. Despite attempts to stabilize the output using Trueplay tuning and manual EQ adjustments, the user reported that the volume level constantly drops during certain programs. Community members suggest monitoring signal type changes within the Sonos app and submitting system diagnostics to support to identify if the issue stems from the hardware or the TV's audio processing settings.
Enhanced Immersion with the Sonos Beam Ultra
Beyond the flagship Arc, the Sonos Beam Ultra is entering the market as a significant upgrade to the Beam Gen 2. Users transitioning to the new model report that the Dolby Atmos effect is more pronounced, creating a more convincing sense of height and space in a compact form factor. The manufacturer has also improved dialogue clarity and expanded the available settings for fine-tuning the listening experience.
While the Beam Ultra updates the audio performance, it changes how users interact with voice assistants. The soundbar does not natively support Amazon Alexa, a departure from previous generations. However, a workaround exists for home theater setups: Alexa can be used if it is enabled on surround speakers, such as the Sonos One or Era 100, before they are bonded to the soundbar. The Beam Ultra remains compatible with the Sub Mini, Sub 3, and existing Sonos satellite speakers for full surround configurations.
Bridging PC Connectivity for eARC Soundbars
On a different front, Sonos users are exploring ways to integrate the Beam Ultra into desktop environments that lack native eARC support. Standard PC optical outputs paired with Sonos adapters typically only support PCM stereo, which results in no sound when attempting to play surround formats from platforms like Plex. To solve this, community members are identifying HDMI eARC audio extractors as a necessary bridge.
Devices such as the FeinTech AX310 and AX340 are being used to provide the required eARC signal to the soundbar. According to community contributors, these extractors can enable formats up to Dolby Atmos, provided the PC's sound chip is capable. Testing indicates that the AX310 maintains reasonable audio sync, making it a viable option for users who want high-end living room audio at their workstations.
The company is also making waves in the personal audio space with the Sonos Ace Ultra. cup-side up or down, whereas the original Ace only rotated in one direction. Internally, the headset features improved Active Noise Cancellation (ANC) and a wider sound stage with enhanced low-end frequencies for music reproduction.
The most significant technical addition is Audio (Music) Switching. This feature allows you to move music from compatible Sonos speakers to the Ace Ultra and back via Wi-Fi. The system utilizes hypersonic sound transmitted by the speakers to facilitate this handoff. Notably, the Ace Ultra functions as a dedicated room within the Sonos app, meaning it counts toward the standard 32-component system limit.
As Sonos continues to iterate on its "Ultra" branding, the focus remains on tighter software integration and spatial audio performance. While new features like Wi-Fi music switching and enhanced Atmos drivers offer clear benefits, the reported volume fluctuations on the Arc Ultra suggest that firmware stability will be a key area for the company to address in the coming months.
