Airplay 2 Support

No my 64bit comment is a question. Do we 'know' those devices aren't 64bit? [...]
We are outsiders, so obviously we do not know, but presumably they aren't. I imagine, a few years ago 64bit chipsets weren't common outside of computer systems.

I think the relevant processing power required is clearly described in the Sonos announcement and it 'somewhat' ties in with the link provided by smilja. I’m afraid I don’t see the actual point you are trying to make sjw?I'm not trying to make a point. I've asked a question (Does anybody have any actual information on what these requirements are that are so above the requirements they currently satisfy in allowing all of the above multi room functionality? Is there cpu intensive encryption and decryption going on? What is the reason?) and the reply was that the hardware needs to support 64 bit processing. So I asked if we 'knew' that those Sonos systems weren't 64bit capable. It now appears to be a presumption that it is because 64bit processing is required and that the Sonos players are not.
The Sonos reason is that they just don't have the processing power (1/16 etc.) - which was why I asked in the initial question if anybody knew what was so cpu intensive in AirPlay2 as to necessitate this power. My guess it that the 1/16th figure is pure marketing and they maybe have a 1/16th of the RAM so are only 1/16 as powerful..

sjw,

Clearly the latest apple devices are 64 bit and I can't say for certain if the CPU's in the latest Sonos hardware are 64 bit or not but presumably the CPU's will need to be faster than the older Sonos hardware devices.

I do know that AirPlay-2 not only supports 2 channel stereo but it also supports 5.1 surround sound and it looks like the audio will be in perfect sync with video on iOS devices like iPhone and iPad (at least).

So I guess that will add to the processing power requirements but obviously no one knows what parts of AirPlay 2 Sonos intends to support. They may only support 2 channel stereo streaming perhaps? Not even sure if that will sync with the video output on the iOS devices?

We shall have to all wait and see. Those are my thoughts at the present time.

I mentioned the 64 bit Apple hardware as that shows the iOS devices are quite capable of shifting around a fair amount of data and Sonos will need to keep up with that for the implementation of AirPlay 2.

Hw spec can be found online. The play 1 speakers has a 64bits motherboard. Play 3 has a 32bit. But it is most likely the requirement of airplay2 with what apple has release so far it is a heavy SW application. I suspect it is more an issue with available ram and processor power that can crunch that hw requirement of airplay2.

I don't think it's anything at all to do with 'shifting around a fair amount of data' - the data you can move around between Sonos now or from a phone (inc. Android) is far in excess than that required from some music files and doesn't need support of particularly quick CPU's - as evidenced by the Sonos system itself and how well it runs on 10year old equipment.
Which is why I was wondering why the demands/requirements for AirPlay 2 are so high and my asking if there was maybe on the fly encryption/decryption taking place. It may well be as simple as Apple require 64bit CPU's and the older (still being sold) ones are not. I asked if anybody 'knew' the answer as there are plenty of people that have taken these things apart so may well know - not speculation.

I suspect it is more an issue with available ram and a processor power that can crunch that hw requirement of airplay2.I do too - and was just wondering why so much 'crunching' is needed.

Airplay 2 has a video aspect maybe you can not separated the 2. Like for YouTube airplay 2 support. Need to see the final airplay2 release by apple to really know.

Good point about video. Although one would assume Sonos only needs to deal with the audio mainly, there may well be some overhead for AV sync maintenance.

We can only speculate till we actually see the end result from Apple and Sonos, but I, for one, will be happy if the AirPlay-2 audio implementation by Sonos syncs with the video on all my iOS devices.

I'm hoping that will also include Apple TV. It may even include 5.1 surround sound, but that's just more wishful thinking.

I am extremely disappointed that Play:1 doesn't support Airplay 2 which I got a pair of Play:1.

Sonos did not clear the differences between Play:1 and One before besides the mic and voice control only. It would be better if you promote as 'advanced hardware' than Play:1. Now I have to get a Sonos One just to get the support of Airplay 2 but only the pair of Play:1 can work as stereo. :S

Nope, Sonos.
