I just noticed that Tidal displays “MASTER” now on MQA tracks where before it would kick down to “HIFI” - has SONAS started supporting MQA?
my understanding before was that even if you were playing the master quality music, it would downgrade to hifi and this was reflected in the display. What changed? Audio Quality or just the display?
i have two gen 2 Play 5s with the sub in my office. I enjoy the sound 😁
Thank you for any input!!!

Actually, it looks like S2 has implemented something similar to Spotify Connect or Chromecast. This is NOT Airplay, it looks legit and it is possible that the MQA stream is being used - however, to no benefit in terms of sound quality if no unfold/rendering is taking place. If there is an MQA unfold happening, an external SPDIF DAC connected to one of the digital outputs (eg the Port’s) would tell you whether there is higher resolution being outputted.
An external DAC would show 24-bits anyway, though it might show 16-bit when the volume is set to Fixed and the original content is 16-bit. It depends whether the DAC spots the empty lowest byte.
In the case of online content Sonos is not supporting 24-bit at this point, so it would be truncated to 16-bit.
Sonos does not include an MQA decoder, and I very much doubt they ever will.
I believe it is a bug in the iOS App. If you use Airplay instead of direct cast/control, it will say HiFi.
Side note/question, because I dont see many active Tidal/Sonos users in this community, could you try my most recent question I posted about and see if it replicates? It would be a huge help.

If you select the SONOS speaker in the TIDAL app, it starts playing, and if you then kill the TIDAL app, it keeps playing, indicating the SONOS zone is receiving the stream directly from TIDAL - same as Spotify Connect or Chromecast.
If you look at the Qobuz app for example, this is not yet implemented so I don’t see that SONOS speaker in the list of output devices.
The new SONOS S2 update only supports 24-bit audio for local FLAC/ALAC files - no support for 24-bit streaming like TIDAL HD service etc.
It’s like they want me to go to B&O.

The announcement says
With S2, Sonos speakers now have support for high resolution audio, 24-bit, 44.1/48kHz for FLAC/ALAC only. This support is for local music libraries shared from computers and network attached drives.
So not online services, and definitely not the folded lossy ultrasonics in MQA.
I’ve noticed under S2 it now always shows HIFI - opposite to my expectations
Now TIDAL shows "just" hifi again for me. interesting ... and I have the same problems as others, When pause/resume TIDAL jumps to the next song. Same problem If I do it in the Sonos app with a TIDAL stream.
Wow this is weird. It seems my direct control is HiFi now and my Airplay is Master. I have the Sonos beam, perhaps there are different symptoms for us as you have a different product, or this has a mind of its own and it is randomly going to show Master at times.
Even I am facing the same issue. Looks like the last update messed with this. Earlier it was exactly opposite.
Hello LuvMusic, if you have time would you mind checking out the post I linked a few comments up and let me know if you have the same issue? Seems there aren’t many Tidal-Sonos users active on here
Hello knopper, I am using iOS and not Android. Moreover, I am not facing either of these two issues you mentioned.
I am facing the other weird issue when using Tidal and Sonos together. “Earlier my IKEA Symfonisk was playing on MASTER (Direct play) and HiFi (Airplay). And then iPhone was playing on HiFi. This has reversed now with the latest update. Now IKEA Symfonisk plays on HiFI (Direct play) and MASTER (Airplay). And now the iPhone plays MASTER.”

**Edit again. This is changing abruptly as I explore it more.**

It also says “Master” when airplay is used.

I have also seen this, do not know if it is a bug. My connect gen 2 hooked up to an external DAC still shows 16 / 44.1. It looks like MQA is in the next version of the Sonos platform (S2). Doubtful though if you will hear any major difference. Have tested MQA via Roon and raspberry pi as an endpoint. It's always nice to see the DAC light up to high resolution, but as I said, I do not notice any major difference. But still it Would be nice to have MQA on Sonos :)
I've noticed the same but it only happens when I'm using an iPad. Not when using my Samsung S9.
Is there an improvement in sound quality?
I love the psychological effect of seeming “MASTER” on the stream quality - my systems has always sounded very good (2 Play 5s 2nd gen and the sub with Trueplay). Is there a difference in sound quality? I have no idea - human interpretation has some limitations. Am I enjoying it? Yes 
Has something changed in the delivery of the music resulting in the change in the display that now indicates Tidal’s “MASTER” label to the stream? That was the question which remains unanswered.
The most important question for me would be: have you noticed any difference in the quality of the sound?
Given the widely known characteristics of the MQA format I await the answer with baited breath...
+17

It will be interesting to hear as info comes out. I am sure there is a psychological impact seeing the higher rate label 😁 I have confirmed that previously it would only display “HiFi”.
Thank you all for the input! Spent the quarantined workday listening to older classics. Love the quality and easy access to so much music!
It’s conceivable that Sonos is taking delivery of a 24/48 stream from Tidal. After all, Sonos will play 24/48 files from a local library. However as of now the 24-bit file is apparently truncated to 16-bit. Maybe with the coming S2 developments Sonos will choose to handle the full 24-bit PCM depth.
Nevertheless Sonos doesn’t support the MQA encoding and, given historical comments that “the math isn’t there” for higher sample rates, it seems unlikely that they would license a proprietary MQA decoder to unpack ultrasonics from the lowest bits, particularly when it’s generally accepted that these could actually degrade the sound.
It used to show “HiFi” when you played the Tidal app through SONAS even though you selected MASTER - when I first got the Tidal app I was perplexed by this and did the research. I was told that the stream was downgraded to HiFi and that was the way it was always displayed until very recently.
The Tidal app doesn’t ‘play through Sonos’ as such. It asks the Sonos player to fetch the stream. Despite the Tidal app advertising ‘Master’ the Sonos player will request what it can handle.
That is the Tidal App playing through Sonos..
