Naim Uniti Core keeps suddenly shutting down. And a few other things. No response from support.

Sounds like you have a lemon that needs an RMA.

Check the core set up and change the power off setting to never, to see if this helps with the shutdowns. The other issues sound like network related matters.

I having core issues also, music stopping via SPDIF, however, will play via upnp....I too have contacted Support via email three times but no response... 

I raised the issue of the Core going to sleep when playing through SPDIF with support back in May. The RnD department were able to recreate the issue - the Core does not always recognise there is a signal on the SPDIF and goes into standby according to the Auto standby time set via the app. I chased a fix for this last week and had a response on the 19th informing me Naim are in the process of testing the update.

My solution was to change the auto standby sleep setting from 20 minutes to 6 hours.

That sounds easy!  Thanks.

I am new to digital; perhaps I could be called an analog dinosaur ????.  So I need a little help interpreting some of the many digital acronyms, like SPDIF. My Naim Uniti Core is connected to my DAC via BNC to Coax.  Is Coax the same as SPDIF?

There was a similar issue with the Atom going into standby when some inputs were selected, specifically Qobuz via Chromecast, which could be resolved by setting auto-standby to Never. Not sure if this was ever fixed, as I ditched Qobuz after the free trial.

Yes, a coaxial cable with BNC connectors is what you use for an electrical SPDIF connection. As opposed to an optical SPDIF connection, aka Toslink.....or a network connection via Ethernet cables.

I had the same issue with my Core. I've playing mine via SPDIF into the nDAC with auto standby set to 10 minutes without any problems. However, recently it has started shutting itself off after 10 minutes during playback. Interestingly, this coincided after I updated the Naim app so I'm guessing this isn't a coincidence.

My solution was to also change to auto standby sleep setting from 20 minutes to Never. I just turn it off manually which obviously isn't ideal. I'm looking to get a streamer soon so I expect I'll be using the Core in uPnP mode rather than SPDIF. 

Hmmm....  I e just changed mine to 12 hours.  Maybe never is a better idea.

I am also wondering if my problems with graphics on the app coincide with updating the app.  My updates are done automatically, so I’m not aware of when it happened, though I know it was updated recently.

From Wikipedia: "S/PDIF (Sony/Philips Digital Interface)[1][2] is a type of digital audio interconnect used in consumer audio equipment to output audio over reasonably short distances. The signal is transmitted over either a coaxial cable with [BNC or] RCA connectors or a fibre optic cable with TOSLINK connectors. S/PDIF interconnects components in home theatres and other digital high-fidelity systems."

Typically, S/PDIF (electrical, optical) is used to denote the interface. BNC, RCA (electrical) and TOSLINK (optical) denote the connectors. DACs can have S/PDIF interfaces, USB interfaces, Ethernet interfaces and others. DACs that have Ethernet interfaces are often calles "streamers". Devices with Ethernet inputs and S/PDIF or USB outputs are often called "network renderers". They are "digital transports": they do not convert digital signals to analogue signals (or vice-versa), they just convert between different digital formats.

Best to call Naim Salisbury and NOT the Uniti BOT line for an automated "human" response

NBPF - Your reply was very helpful.  Especially helpful was discriminating  between the interface and the connector and learning the appropriate terms.  The terms make more sense now.  Thanks.

Rather than emailing support try phoning them, that's what I did when I had Core problems. They walked me through several trouble shooting sessions. Rich 

My Core has just recently started playing albums on Tidal from the 2nd or 3rd song on and stopping 5-10 seconds before the end. Quite annoying... This seems to have gotten worse after upgrading to the new App version! I have rebooted the system, did all tricks I thought it would help but the problem is still there. When I play Tidal on my iPad this is not a problem. Any suggestions?

Your Core plays Tidal? A few people here might be jealous!

What Chris means is that the Core won't do Tidal so it must be your streamer that has these problems with Tidal, not the Core.

Does the same on the analogue input.

Mine doesn’t! I have standby set to the minimum, and it only overrides playback on Chromecast. 

Sorry. I meant to say Uniti Atom. This is my equipment and it plays Tidal... Still, it is not working properly!

Do you use AV Fixed Volume? I do, and it turns itself off. It's random sometimes it's fine other times not. It's changed every firmware upgrade and I'm on my 2nd unit. So its a feature bug.

I don’t know what AV Fixed Volume on an Atom is! I do occasionally use the HDMI ARC input from a TV, which is the only input it has with a wired connection. It’s been a while since I had this issue with Chromecast, so I’m not sure if it has since been addressed with a firmware update.

AV Fixed Volume is for analogue input and sets it as a pre amp in to take a preout from an AV amp so you can drive the same speakers for the front two channels of your 5.1 system. So AV amp does the rear, sub and center atom powers the fronts. 

I have tried all possible tricks and with the recent App upgrade and current firmware version now the system does not recognize Chromecast. It keeps starting an album from the second or third song and it stops before it ends. Shame on you, Naim! And I have read several threads that talk about problems whenever there were upgrades. And Naim's customer service does not respond to my emails.

This is my second unit of the Atom (the first simply froze and it would not work anymore - it was changed at the dealer) and I am very frustrated with all that.

Should I go back to factory settings and try to restart the system?

You would probably get more responses if you started a new thread with a relevant title about Atom rather than posting on an old thread which is about UnitiCore.

Getting a reply to an email to Naim support is a bit hit and miss currently unfortunately. You could telephone them and at least talk to someone but their advice to anything that the person you speak to doesn't understand will be "go and talk to your dealer".

You certainly could try a factory reset of your Atom, but others who have an Atom and use Chromecast (I don't) may have other suggestions.

Renato, as David advises above, I think it's best you start a new thread regarding the difficulty you are experiencing with the Core.  And before you do so, please do make sure you have involved your dealer. I will close this thread now so you can start a new one.
