NDS Stops playing

Posted by: Dustysox on 17 December 2016

Hi all,

Before I send my NDS to Naim i wanted to "pick" your fine brains!

My NDS recently "acquired" a wee problem in that it stops playing from Asset Vers 5. I have a Mac Mini with an external hard drive connected to it. In the last 4/5 days the NDS stops playing the music. 

I still have my old Logitech Transporter which uses Logitech Media server which doesn't seem to suffer the same problem i.e. connecting the external hard drive on the Mac Mini and playing music.

I have rebooted (i'll whisper this bit...!) BT Hub 5 router. This didn't solve it. I then carried out a full factory reset of the router, this did not solve it. I swapped ethernet cables..this did not solve it. What is strange is that switching NDS to radio station it does not suffer the same problem. So, with my detective hat on I can only conclude that either the Mac Mini and or Asset are my problem. I have uninstalled and reinstalled Asset and this has not effect. I ran a check on drives in Disk Utility last night which did  find some errors and corrected them. This has made the Mac Mini a bit more snappy! I am going to reload Miniserver to see what results that brings. 

When I open Naim app it does seem slow to find UPnP.

I have unplugged ethernet cable to NDS and now running NDS in wireless mode to rule out ethernet connection on NDS. 

Before you all shout get a Uniti Core, can any one suggest what i can do next? I'm running out of ideas.

Hi Adam,

Can you elaborate? What would you advise?

By the way, using a NETGEAR GS116UK 16-Port Gigabit Unmanaged Switch.

Just cut out with Minimserver. DAM.....Guess this rules out Asset.

either the Mac Mini or router?

Did buffer underrun cause the dropout?

Dusty,

Do you have any spare ethernet cables? If so, try swapping a new one in between the switch and the NDS just in case it's the cable playing up.

Good point, it's always possible that a damaged cable is the culprit. I keep a long one spare for checking this - you can buy basic Cat5e cables online for next to nothing.

Hi SJB,

im not sure what this means? It does advise when cutting out Please wait initialising input on NDS screen then finds UPnP?

I did try this without success. 

What is curious about this the Transporter looking at same Mac & external hard drive doesn't suffer the same fate.

any thoughts?

Im hoping with Qnap arriving tomorrow this will answer some questions and add to back up of my music at best.

Hi Adam,

Just a short re-cap of a typical streaming network set up. Please forgive if I'm stating the obvious, but in this case I feel it's good to lay out some basics, so that we can work from a 'known state of affairs'.

Please have a look at this picutre (courtesy of Mike-B):

* Your Internet-Service-Provider modem connects via CAT5 (or higher) to a switch.
* Router should be running DHCP (so that it assigns IP addresses automatically to all network components)
* All components connect to a switch in your case Netgear) via CAT5 or higher cable.

The above is a fundamental wired network, which works well with NAIM streamers.

If you could list where your network differs from the above model, we can try to identify areas to be checked.

Once all of those steps have been tested, we will need to check your NDS.
Before you start I would also advise that you perform a factory re-set on your NDS.

You said above "buffer was full". I think you can have the display showing the buffer level while playing and then you can see if the buffer is the issue with the cut outs.

A 16 port switch suggests you have quite a complex network setup. 

Might be an idea to temporarily simplify the network by having only the router, MM and the NDS connected to your switch to see if that makes a difference. I take it that you've also tried swapping the port that the NDS is connected to.

Hi all,

Right, I have ordered QNAP TS-253A-8G-6TB-RED QTS-Linux Combo . It would seem sensible to have a system in place to make things a bit more stable. Is this model ok?

The 253A is good, and is what we use.

Sorry to hear of your issues Dusty.

One can never be sure. I suspect the NDS is blameless.

Might the dealer come out and test your setup and network? They must deal with these sort of issues from time to time.

I concur that using a NAS is a reliable and logical move which may resolve your issue in the process. QNAP runs Minimserver just lovely. It will run Asset too. I use both (plus another one for video to my telly) and nothing trips over anything else.

Here's hoping.

Hi Adam,

Thanky you for this info. I have seen this before and tried a back to basics approach . "Rewired a very basic connection path from the router to the switch/Mac Mini & switch to NDS. Still no joy, so frustrating.

I'm giving up for today until Qnap arrives tomorrow. I can then load Asset on this and see what results I get. 

I really am hoping there is something wrong with the Mac Mini Ethernet etc rather than the NDS.

I am still keen to "beef" up the network side of things + back ups etc.

im no expert in all things networks, your wise words are most welcome. A fresh approach from a third party may well see the woods from the trees that seems to be bypassing me at the mo.

Glad to hear that you're getting it sorted Darren.

Best wishes for Christmas and the new year.

A good strategy, irrespective of your current problems, which you may find disappear without ever being diagnosed, as is so often the case with these issues. Fingers crossed!

I haven't read the whole topic in detail, but your initial post is symptomatic of degraded performance of the Mac Mini thingy.  And if a disk scan pulls up errors (even corrected errors), this would be reason enough for me to abandon its use completely.   A move to a dcent NAS drive seems the most sensible way to go from here Dusty.  I noticed a few suggestions as I skimmed through - me, I use Netgear, but I also have high regard for QNAP.

Go ahead, bite the proverbial bullet, invest in a NAS and give the Mac to SWMBO, the grandkids or a local charity... hey it's Christmas after all; treat yourself.

Dusty, let us know how you get on with the NAS, I really think it's unlikely it's the network, it is possible of course.. but there are more likely suspects... I think isolating your Mac is the best thing to do.. networks can only work as well as good their hosts... garbage in, garbage out...

Good luck

Simon

Cheers Roger, good advice...please forward your bank details...seeing as it's CHRISTMAS!!!!

Im suspecting the Mac Mini which to be fair has done a sterling job.

Sure will Simon.

Sat with glass of red and tree all nicely decorated and music...no..it's stopped...it's started....no it's stopped!!!!!

Roll on tomorrow. I will report back.

Hi,

Qnap turned up all safe and sound.

After initial set up, now copying music across from external drive on to "new NAS"!! 

Installed Asset and now playing music. I will monitor to see if it stops playing....fingers crossed!

More to follow.
