I have an Arc and I play Atmos content and I’ve never encountered this. I don’t doubt that some people have problems but, then again, there are plenty of Apple bugs that haven’t been fixed that I’ve never encountered either. Welcome to the world of tech.
Me too. I've had Arc for towards 4 years now and never had one pop. So I believe this is one of those Apple-like "affecting a small number of (total) users" as even the comments to that story include people saying they've never had the problem.
However, in fairness, I helped a friend set up an Arc and two 300s about 5 weeks ago. Due to some third party noise in the area, we couldn't use the Sonos "Trueplay" for auto-tuning the setup immediately, delaying that for about 3 hours. Everything sounded great for those 3 hours. When the third party noise ceased, ran Trueplay and this problem immediately manifested. It sounded like the speaker was loudly popping regardless of what was played including non-ATMOS stereo music or even the sound effects made by using the buttons on top of Arc.
What changed? We ran one bit of software. So, I factory reset their Arc and set it up again without running Trueplay. Fantastic Sonos sound from the
SAME sources since (CEC and ATMOS settings on, same sources, same cable, etc. In other words, no other variable changes). Since that day, it has sounded exactly as Sonos users expect. No pops.
My assumption is very Apple-like: a bit of software has some bug(s) and they may be "one software update away" from fixing whatever it is. Obviously, my guess is that it is in the optional Trueplay run... which I've run myself on my own Arc several times and never had a problem. That makes me think maybe it's in using Trueplay with select combinations of speakers. For them, it was Arc + twin 300's. For me it's Arc + Move.
If it was a hardware thing and/or affected ALL Arcs, you & I would be experiencing it with our Arcs too. And if it was a hardware flaw affecting my friend's Arc, it would have repeated
after the factory reset because all other variables remained the same. It did not. To me, that simply screams software bug, affecting only
some units.
If someone wants to buy, buy. If you get one that pops, replace it... exactly what you would do if you buy something from Apple and it isn't working right. While I am no burning fan of SoundBars myself (believing the traditional Receiver + true (at least) 5.1 setups maximize home theater sound, Arc is generally rated best or near best in most objective head-to-head comparisons. And my objective ears certainly agree that it sounds great.
Especially for Apple people since Sonos so readily works with
Apple Music and
Airplay and
HomeKit (so Siri commands work), it's a great option instead of HPs, minus the heavy lock-down, with much more flexibility for all of the many wishes HP owners have that Apple may never act upon like:
