So, music was playing, stopped mid track. I went into the app and it couldn’t find the ND555 as a room. When I looked at the unit the Naim logo appeared on the screen. After a short while it was available as a room and I could play music as normal.
I’ve had the unit since mid December and this occurrence has happened twice. Once last week (Thursday I think) and again tonight.
Spontaneous reboots, often preceded by stuttering, are a well-known problem that has plagued streamer users for some months, some more, some less or not at all. It was partially addressed by firmware updates but not completely. Another update is expected soon that will hopefully fix it for good.
From the long-running firmware thread, already some time ago:
I wouldn’t overreact. The forum attracts reports, and some members are clearly affected more, but e.g. my dealer was not aware of the reboots, so it’s apparently not that many. I had one instance in several months. Follow the instructions and chances are you will not see it again. Should not happen, of course, and it lasted far too long, but it also does not really diminish my joy with the NDX2. Fingers crossed for the next update, should not take much longer
I received my ND555 last September, at that point it ran 3.5.0 firmware - In the short time I ran that before 3.5.1 became available I had no random reboots. Since running 3.5.1 (pretty much on day of release) I think 5-6 random reboots in that time. That seems to be right in the middle of others experiences. I have not once bothered doing a hard restart/reboot. I did report to Naim and was told to hang on for the next update. Does seem to be imminent by the chat on here.
As others have mentioned, there’s a Fw update that is imminent that should fix this. What would be interesting to know though is whether your dealer experienced the same thing. I would have thought not otherwise they would perhaps have not lent it out on extended demo. It could point to it being specific to certain networks or network setups, which might also explain why so many users seem to be unaffected, while some others can be affected by it. However, it will be interesting to hear back from your dealer as to whether they ever experienced such things at their shop or elsewhere.
If it reboots and then is ready to start again, there is no need to restart routers and reset the player. It’s not a network thing but rather about how the player handles data inside itself. There is new software in beta that should resolve the issue and hopefully it will be available as a general release soon.
