If you’ve been plagued by unwanted noise coming from your Sonos Arc or Sonos Beam (Gen 2) soundbars, we have good news: there is finally a fix, rolled out a few days ago, reports FlatpanelsHD.
The fix stops loud popping and crackling noises that some owners have reportedly experienced with their Sonos soundbars when streaming audio from an Apple TV 4K or Xbox Series X.
The problem had been plaguing some Sonos soundbar owners since late 2020, but the company didn’t admit there was a problem until August of this year – and even then, their solution wasn’t great. The fix is available now. To get it, just make sure your Sonos mobile or desktop app is up to date, then download the software update for your subscription.
Sonos apologizes for ‘rare bug’
The issue appears to be related to audio from the Xbox Series X and Apple TV 4K, both of which transmit Dolby Atmos over PCM uncompressed with metadata. This is supposed to be a good thing – other devices transmit data as a compressed bit stream – but in this case it wasn’t, because Sonos’ Dolby decoder handled the errors in an unfortunate way.
As Sonos explained to The Verge: “Sometimes a Sonos product receives a corrupted audio segment from an external source and needs to filter out the unwanted audio. The bug we identified allowed our Dolby decoder to play audible errors on some home theater setups. rather than hiding them. »
I wasn’t personally affected by this one, but my best friend was – and it completely ruined the joy of new technology that you expect from high-end audio products. She spent countless hours trying all kinds of solutions, but none worked. The suggestions he was given were to turn off CEC device control to make setting it up less convenient or to switch from Atmos to Dolby Digital 5.1 – not ideal for a product purchased specifically for its Atmos capabilities.
Sonos apologized for the delay: “We apologize for the disruption caused by this bug and would like to thank you for your patience while our team developed a fix.” But the problem is not so much that there was a problem, but that Sonos said there hadn’t been one for almost three years…
