New firmware update

Hi Clive, that’s what Tech Support is there for.

Now that I am pretty sure that it happens for me after a long session over HDMI, tonight I will switch inputs first before putting the headphones in as a test. If it no longer does it, I will be pretty sure it is related to the HDMI. And work was done on HDMI ARC in 3.5 according to the release notes.

If it is amplifier related it should always do it after a long session with any input.

Mine was definitely after a short ‘session’, so I would say consider that that the length could not turn out not to be a factor. Unless it is different issues of course.

Both could very well be true. Just that I have not been able to reproduce it willingly and only after a long session it happened. Could be that I do something to trigger it that you do in a “short” session.

But these things are the worst. Issues that you cannot properly reproduce.

I would be happy being sure that it is firmware related and not a hardware thing cropping up. But the fact that you are getting something similar AND that it only started after the update makes me lean towards firmware at this stage.

If you’re referring to random reboots, than you won’t be able to reproduce them willingly (at least not easily).

Random reboots are often due to improper memory management or to buffer overflows.

From a software engineer point of view that’s the kind of bug you don’t want to be confronted to… meaning this is the kind of mistake to avoid!

We’re talking about a different issue, noise from/after using HDMI. Although our experiences do not exactly match the issue sounds similar.

My Nova has done the weird “bzzzzt” thing again when powering on yesterday and today.

I’ve been using HDMI ARC but I switch the unit to an analogue input before switching off the Naim. (To prevent it from coming on unnecessarily next time the TV is turned on.)

Three different experiences but it does sound like it could be related indeed.

Going to see tonight what switching to analogue input does for me.

Can’t test that in my scenario as it shut off while on HDMI, so turning it on will automatically activate the HDMI again

At work we once ran into such a situation. Appeared that the software vendor had put ‘on error resume next’ into the code in several places. Let’s assume Naim has done a much better job when coding the software, so it should be traceable and solvable.

Not cool…

Designing/Writing software can be considered as an art. Unfortunately not all software engineers share the same view.

A long time ago, I participated to the OpenBSD project. State of the art coding!

Luckily I am not facing that… yet.

I am talking about a zzzzzt type noise I head sometimes on plugging in the headphones. Technically that could also be related to pointers and buffers as well.

Did this happen when you were streaming lokal from nas/pc or when streaming Qobuz?

In my case the nd5xs2 is solid on nas streaming but I’ve never been able to play a compleet album through Qobuz without stops after one or more tracks. This is going on as long as I have device, august2019.

Streaming from my local NAS.
This may be related to your internet connection. However, you should report this to Naim Support.

Thank you, yes guess I have to.
After I 've done some total rebooting on the network devices, and start up with just a modem streamer canle connection . If its still there I will contact Naim .

Gerben.

Update-

So I’m listening to City and Colour “Woman” and ND555 has just had a reboot. Please add my “Naim” to the list please.
Working again now, and I suspect Naim will be full on working on a fix.

Not the end of the world.
Choose music, and press play Dusty!!

Sorry to hear/read that. I happened to me too, and my Naim is already on the list.
Have you emailed to support?

Hi Thomas,

Only happened few minutes ago, so will probably email in the morning.

Hope you’re well, I don’t spend as much time as I used to on this fine forum but I do so enjoy reading about your journey, keep up the good work!

I had a email from Naim advising that setting the standby time to never fixes the stutter and reboot issue until a proper fix is released:

“ We have had a couple of reports about the stutter, apparently, changing the auto standby time to “never” resolves this until a fix is released.”

See Richard’s post number 745.Please do report your random reboot incident to Naim Support, otherwise there’s a risk they won’t realise how widespread it is.
