Can you not output audio directly from your TV using SPDIF/TOSLINK and input that in to your NDX2?
Your AV amp might also have a digital output you could use to achieve the same goal.
I’ve owned an NDX2 from new, you’ll want to give it more than a few weeks to settle in, might be obvious but make sure the firmware of the NDX2 is up to date and current.
Thank you. The NDX also has a USB socket, which I used once or twice, so I don’t see why the Naim app for the NDX2 has to show something that is not required … especially as it takes first place (i.e. above “Asset UPnP” and “Minimserver”
It’s not even listed alphabetically! 
Once you are using your Qnap you don’t need to use the screen that shows local servers, so it’s hardly an issue. It’s there should you want it.
It was probably the “upgrade” from Chromecast Audio to Ultra.
I looked to buy the Audio widget (nearly 2 yrs ago) but they’re no longer available,
Eh? When the user commences streaming the NDX 2 screen shows the various input options, UPnP being the one I normally choose … sometimes TIDAL (whilst I have the service), sometimes BluRay or CD … maybe even Internet Radio.
Once I have chosen UPnP I’m faced with the list of Servers, of which Local Music is the first.
Hence I don’t understand your comment.
I tried the option, last year (and queried/reported my findings on another thread), of using the AV’s Optical Out:
It didn’t work.
Thank you all for these replies but I’ll call an end to this Chromecast issue now … it’s a subject for another thread … I wanted and did highlight the fact that the NDX 2 does not accept Chromecast AV signals.
Cheers
The USB implementation on the NDX2 is completely differently to that on the old model. It appears in the Server input because it can be accessed by a built in UPnP server that runs on the streamer, giving a better browsing experience than via the USB input and allowing other devices to access the music too.
Just because the NDX had a USB socket does not mean that it could serve these files via UPnP to other streamers and to itself, like the NDX2 can.
On the NDX2, going through Server > Local Files provides a full-featured UPnP browsing experience with metadata, which going through the USB input option does not (the USB input option only gives a folder/file view)
It would be neater if Local Files was only displayed if a USB drive is connected, I don’t know why this is not the case
I’m sorry, you are quite right. I’m so used to it I just don’t notice it. I do agree that it would be good if the local server option could be removed when one is not connected. Maybe @Will could add this request to the list. Thanks Will!!
Thank you, ChrisSU and Duedkiez, for this valuable information - I certainly hadn’t picked up on this (and neither had my Dealer when I asked him). I may use the facility one day, but agree:
Okay, end of … move on 
The NDX 2 has the Standby function - which I’ve left at 20 mins, max’m appears to be 2hrs. This appears to be very sensible even if 20 mins passes very quickly!
But when woken from Standby the App displays the Source Input Screen … UPnP has to be chosen even though this is my default source. I have ordered the inputs as I want so that UPnP is top left … i.e. first choice.
Query: is it possible to have UPnP automatically selected when coming off Standby?
Added to which, the last album played is still showing at the bottom of the App screen. So whilst the App appears not to remember what the last Input Source was, it does remember the last album streamed … weird!
Further, when we look at the NDX 2 screen, UPnP (my default choice!) does not show and is not selectable (not even via the Screen Input options), yet e.g. Spotify, which I do not use, is.
Are there technical reasons for these anomalies … or just not properly considered?
Has own source UPnP become second-class behind pure streaming?
Cheers!
There are, I believe, some technical reasons why UPnP, Tidal and Qobuz can’t be controlled from the remote/front screen. (Neither can Spotify really, you use Spotify Connect from its own app.)
On the face of it this does seem a backwards step from the old streamers, but that’s the way it is.
Again, thank you for enlightening me. At present Spotify which appears to be selectable shows my son-in-law’s login name … he used it briefly a few weeks ago with his subscription.
Clearly we’re guided towards using the App (I used the front screen a lot on the NDX) and the NDX 2’s screen is of limited use. Choosing inputs such as CD, AV and Internet Radio change the NAC 282 input accordingly (this works very well) but the primary one, for me … i.e. UPnP … isn’t available … oh, well.
Taking this issue further … more queries:
We often queue several musical works but find:
Is there a setting I’ve missed which will re-instate this useful (and desired) facility?
Surely these must be firmware/software programming issues - or, again, have I failed to make a necessary setting change?
Many thanks - in advance.
NDX 2 … the screen:
I’ve read numerous postings suggesting the screen ~ album art ~ is not particularly useful; once you’re used to the change from the NDX, etc. … what’s the point? Those who chose the ND5 XS2 cite the screen as not being required.
And, yes, I’ve noted that in all things the User is driven towards the App … so why bother with the screen?
I can state: I love the screen … I enjoy casting my eye towards it for nearly every album that streams. And, in this regard, I spend (an inordinate amount of) time seeking artwork to attach to music files (i.e. not just the cover which adorns the CD purchased). For collections of older recordings (such as 45rpm singles) I like to use the vinyl label or picture sleeve; for re-issues I often look for the original release artwork, etc.
But, there is something else I’d like: the Hand-control has a button to access the track details but this secondary screen (small image + details) stays on for about 5 seconds.
Can this not be adjusted to say - 10~15 seconds? Okay, many won’t be bothered but if, e.g., I want to identify what track is playing on an album such as Harp Music of France [Laskine] (my title) and it’s Caplet: Conte fantastique d’après une des Histoires extraordinaires d’Edgar Allan Poe “Le Masque de la Mort rouge” (Légende) … it takes far longer than 5 seconds to read 
That the information does not scroll across the page is also disappointing … again could this be re-instated (or have I missed the relevant optional setting)?
Perhaps an extreme example but if it’s possible to extend the display time / re-introduce scrolling … please!
As for the Hand control … the less said the better. Awful tactile feel, of little use beyond set-up. I know … use the App.
I’m not sure if this issue is specifically related to the NDX 2 but it’s occurred only since we replaced the NDX … almost 5 weeks ago.
App: Random play
On a number of plays we’ve found the music queued is played in random order and, yes, the Random icon is lit … but we’ve not selected it. We did have one or two occasions when the Repeat facility was engaged, too, without intention.
Probably thick-thumb syndrome but it raises the question: as useful as these facilities may be, why are they placed in such a dominate position on the App front page? Are either used regularly by most users? For me, in 8+ years of NDX streaming I’ve employed random no more than a dozen times, repeat … never.
I’ve no desire to see either facility removed but do suggest:
The app is long overdue a revamp of its button layout in my view, especially on small screen devices. For years the forum has been scattered with posts from people tearing their hair out because they can’t figure out why their play queue is playing in random or repeat mode, amongst others things.
The shuffle setting is ‘sticky’ in that if you turn it on to listen to a playlist, it’ll still be on when you go to listen to an album (even, it seems, if that’s in a different listening session altogether) but I think this was the case on the old platform too. I’ve got used to checking this, but it still catches me out occasionally. I don’t know whether there’s something that turns shuffle on automatically - but there shouldn’t be.
Personally, I’d like two settings for shuffle - one for playlists and one for albums.
Thank you, both, for your replies.
We don’t use Playlists (I’ve never found out how to set one up which shows my ignorance) but accept your warning should I ever do so.
I referred in my second post to having a telephone conversation with one of Naim’s technical staff (initially regarding Chromecast but we covered a few other issues) and he agreed with me that the Random (Shuffle) and Repeat Buttons require attention … indeed this matter was already scheduled.
I hold out hope
Yes it’s annoying, I would have thought shuffle should default to off when you change album / playlist or whatever.
