Description:
There's a problem with some Dolby Atmos signals that's causing unwanted artifacts on the Sonos Arc.

FULL STORY ======================================================================

The Sonos Arc is one of the best soundbars you can buy today, which makes it all the more frustrating when it experiences issues you just don't expect audio problems on a soundbar that costs so much money. But some users have encountered just that, and they've been trying to get Sonos to take them seriously for some time now.

I haven't experienced this myselfmy surround setup is based around an AV receiver but my best pal is a serious Sonos fan and she's encountered the
same problem as others. When the Sonos is connected to an Apple TV 4K or Xbox Series X, the soundbar emits loud popping sounds. And by loud I mean really loud.

The problem appears to be down to the way those devices transmit Dolby Atmos
: while many devices transmit the audio information as a compressed
bitstream, the Apple TV and Xbox send it over HDM as uncompressed PCM audio with metadata. That, apparently, isn't too popular with the Sonos soundbar
and appears to be the cause of the problem. It doesn't affect everyone but it seems to have affected quite a few users.

So, how do you fix it? Sonos is still searching for a fix

Like many other Sonos users, who've been trying to get this solved for over two years now, my friend was told of two workarounds: disable HDMI CEC or disable Dolby Atmos. But both of those workarounds mean losing functionality: CEC control in the former and Atmos audio in the latter.

Sonons has now issued a statement to The Verge acknowledging the issue.
That's the good news. The bad? There's no fix yet.

According to Sonos, the firm has been finding it hard to reproduce the issue. That's echoed by KeithFromSonos, a Sonos employee who's well-known on Reddit for answering customer concerns: "I hesitate to say a fix is in the works. Only because I dont want anyone to get tied to the idea that something is coming soon," he writes. "The team has been and is actively working towards a solution, the biggest issue we have is reproducing the loud pop.

The news that Sonos is at least trying to find a solution is good, but of course that's not much consolation to anybody who's shelled out on an expensive soundbar only to have to limit some of its key features. For the time being, if you want to experience full Atmos on your Apple TV 4K or Xbox Series X, it might be wise to consider one of the best rival soundbars instead.
