HDX skipping tracks with NAS (sporadic but frequent bug)
Posted by: Yvan on 26 February 2015
Hello,
Since months now I'm struggling with my Naim HDX and my Synology NAS (DS412+). My HDX is running on version 1.7b. For a description of the stores I'm using, see the end of this post.
Here's my problem:
1) I can play perfectly my music streamed from the NAS to the HDX during one or two days sometimes, and sometimes just an album and then...
2) suddently during the play of any album, the HDX starts skipping from track to track and plays only 10 to 20, sometimes 30 secondes of each tracks. 
3) at this step, if I try to play any of the albums from my NAS through a simple player on my Win7 computer, it stops reading also after few seconds, saying that there is a problem with the file description. (so this is pleading for a problem on the NAS huh ? 
)
4) but if I lounch a rescan on the Main store, and on the network shares (host scan) through the Naim Desktop Player, it's usually (though not always) solving the problem without having to restart the NAS at all (so this is rather pleading for a problem on the HDX now ! 
.
If this was happening only with some of the albums, and if it was occuring the same way before and after a rescan, I would say it's the concerned album that has its files corrupted or badly ripped. But as the problem doesn't occur again on an album that was skipping tracks, after a rescan... I guess I can say the files are OK.
My connection between HDX and the NAS hasn't change and is wired in RJ45 Ethernet, double armored. (HDX <-> modem <-> NAS).
Can anyone help me please ? Unfortunately I still haven't found a way to trigger the bug, therefore I'm left with no trail to follow. And it's really painfull to have this wonderful player of Naim that's sporadicly skipping like this when one wants to listen to some great albums ! Is there a way to log the events on the HDX ? or any other idea ?
Thanks in advance !
My stores and network shares are organised as following:
1 folder on the NAS (332GB - 854 folders - 9584 files) used as main store from the HDX with only the ripped music from the NAS on it.
3 network shares: one with (17.88GB - 83 folders - 2208 files), another with (168GB - 943 folders - 9447 files) and the last one with (4,67GB - 20 folders - 123 files).

Thanks Paul !
First, your post made me understand the utility of that Naim NAS simulation tool... With that name I was thinking that they've made a tool to simulate a NAS for the Naim device... and didn't understood the utility. But it's rather a Naim NAS testing tool !
I made a first test and during it, the 'simulator' said multiple times that the specified network name was no longer available. This made me think about fixed IP on the NAS. I was not sure to have a fixed IP adress for it. On my Internet router, I had 'Static IP' writen beside the IP of the NAS. But surprisingly that IP was changing from time to time. So finally I dug into this and found out how to force my NAS asking for a fixed IP (at first I was thinking I had to set the router to give a fixed IP... but it seems like it's the device that has to ask for it, not the router).
I also suspect a custom connection I've made for an analogical old phone (impulses dial) in parallel to my frequency modern phone devices. So I did disconnect that old phone for now. As my phone network is also connected to the router, I might have put some bugs into the router from the old phone connection. This could explain why I had a sporadic failure. I mean when someone was calling us, or when we were calling someone, it could have made a problem on the router and that one was redistributing IP addresses. But the HDX wasn't able to retrieve the NAS because it has changed it's IP adress. And with a hostscan it did retrieve it.
That's my hypothesis now. Since I made the change for the fixed IP on the NAS, everything's fine. I did retest with the Naim NAS 'simulation' tool, and it did pass after 12 hours test. I cross my fingers now.
I'll keep you posted...
