Can people stop complaining about DTS?

It isn’t just you, I do the same research before spending my hard earned dollars.
So when you research a brand new car, you specifically make sure that it has a left-hand turning signal or don’t you just assume a brand new car does those basic things?
Not a valid comparison. In most countries a functioning left turn signal is a legal requirement for road-worthiness.

But if, say, I wanted a satnav then of course I'd check the specs.

It's a shame, as it is a reason people will move away from sonos in their "theatre/main room", and then it's not whole house sonos anymore.
Still if gives good techy reasons for playbar2 🆒

Users with a serious need for a "theatre room" most probably won't have gone down this PLAY* path anyhow. They'll have a receiver with passive speakers dotted around the room, quite possibly hooked up to a CONNECT/ZP90/ZP80.

Amen!! Another rational person who lives in the “real” world. :D

If you only knew who you were replying to . . . 😉

My theater room accommodates Sonos just fine. I use a Connect (actually a ZP80) outputting to an actual A/V Receiver instead of a compromised soundbar. Then again, I also research before I spend $700 on a piece of electronics.

I see it both ways. I definitely agree that it's rather wise to do research before buying any tech these days. You just can't assume features. At the same time though, if I see an optical output on my tv, and an optical input on the PLAYBAR, I expect that they're compatible. I sort of feel that an average customer shouldn't have to know more than that before making a purchase.

In a way, this is an industry problem more than a Sonos problem. On one hand, it would be great if a new codec came with a new type of connection. That way there would be no doubt about compatibility. Of course, the downside would be all new cables and such for the customer to buy, as well as no firmware upgrades to support a new codec. It's growing pains.

Although I already have my setup, I have thought about upgrading to a 4K. If I start looking, it's going to be annoying that I'll have to limit my choices by what will work with the PLAYBAR, or possibly have some complex work around that limits the ease of use. Essentially, I'm fine now, but I certainly would be in favor of making the Sonos as compatible as possible.

Been waiting for this since about a year after the PlayBar came out. We thought the PlayBase would be it and were all geared up to get a PlayBase for the living room and move the PlayBar to a bedroom, but no not to be!

Exactly!! Serious users know what they want (DTS) and would know to look for it. It is not an unreasonable assumption for a normal user to think that all Sonos units would just accept all standard inputs (as the ZP100/ZP80/Play 5s at the time did), after all one of the original (back in the day) Sonos USPs was how simple a set up the system was.

I remember all the forum traffic on this DTS issue as well as the lack of HDMI inputs when the PlayBar came out. There were lots of cleaver workarounds that users came up with just to get the PlayBar into their Sonos setups. Why bother? Because if you want; better "stereo" than your TV came with, want to be able to send TV's sound around the whole house and are not too fussed if the surround sound is not up to true theatre room standards then the PlayBar setup does a good job and we love ours.

We purchase our PlayBar, Sub (matt black is best!) and Play 1's knowing full well of these two issues. Many people thought that Sonos had dropped the ball, me included (and I have not changed my mind in the intervening years!) but we all hoped that at some point Sonos would bring DTS to their system.

I have no idea why this has not happened, there might a valid technical reason but I am not qualified to understand these things! Or it might be that Sonos just do not want to go back on their decision and be seen to have lose face. Whatever the reason I for one still hang onto my hope that DTS (and HDMI?) will make it to the Sonos system at some point either in an update or a PlayBar 2.

Of course I may end up in a "sod's law" position, that the upcoming OS update in April brings both DTS support and at the same time the death of the CR100, then what will we do?? :?

Yet another Sonos buyer who can't handle any criticism of their choices. Talk abut thinking. You posted a topic complaint you don't like seeing criticisms. Is the irony totally lost on you?
Nobody is forcing you to read the very justified complaints about Sonos Home theater gear not support modern formats or connectivity.
This is Sonos' market to lose and judging by the complaints and returns they are being very slow to respond. There are many alternatives now.

A £50 Samsung Blu-ray player solved it for me (on the fly DTS to DD conversion), but I knew I'd need to buy that before buying the Playbar.

For what it is and what we use it for the Playbar in 5.1 works perfectly well.
