streaming from Synology - issue

I always reduce the complexity of a problem by making it as small as possible.

In this case I would put the NAS next to the Streamer, use another cheap switch and 2 simple cables.

Then reproduce the problem.

If the problem still exists, one of the 2 legs needs to be replaced to get closer to the root cause.

I would in this case connect another streamer/ transport to the network and see if it behaves the same.

Exclude possibilities.

I've been running an Airport Extreme inside my ISP supplied router for years and it works fine for both WiFi and Ethernet. The router just has WiFi disabled but is still my DHCP server. For me this has been a much better solution than just relying on the router do do everything and if the OPs TP Link is set up right, presumably it could do the same. 

Exactly Chris - most modern consumer devices whether they be routing  switches or switches have proper switching chipsets - often from vendors like Broadcom - the key thing is to ensure if being used at anywhere near capacity they have proper heat sinking. There was an issue with Netgear GS standalone switches a while back where they would crash or lose data due to overheating through poor cooling - and the same no doubt has happened on routing switches from ISP providers in the past too... in fact I think Mike mentioned overheating on an early BT HomeHub device.

Just a suggestion to the OP - can you log onto the TP switch and look at the ports that connect direct  to the Naim streamer ... it should read 100Mbps Full Duplex. If it says half duplex or less than 100Mbps then you have an issue - either a cable problem or compatibility issue between Streamer and Switch.

Also the NAS should have at least 100Mbps Full Duplex at both ends on the NAS and Switch.

.......  just so, I had a HH3 used as a switch the first weekend I had my NDX.  The NDX stopped playing after 2 hours (gulp) ,  found a strange smell coming from the HH3, it was so hot the plastic was soft.  It came back to life after it cooled down,  but it had a pukka switch added next morning.

The overheating & failing Netgear switches that I've heard of are the newer 2 & 6 series desktop items,  I understand its a capacitor failure.  The old 1 series run with no detectable heat,  I've measure my GS105 after running over 3 hours continuous & my Fluke t.meter can't read any change.   The power consumption is ~1W with 3 ports working so not surprised there is no detectable heat.  Maybe a few reason why Netgear guarantee the 1 series for lifetime & the newer series of SOHO units for 3 years,

Hi Simon,

I was searching for those setting at my TP-LINK but unfortunatly I couldn't find. I will also send an email to Synology support center with request to check my server ( can be done remotly, most of the support team from Synology is in Taiwan)

Kacper

I know that the consensus seems to be that your problem is network related. However, it might be an idea to copy a few of you 192kHz AIFF files on to a thumb drive and play these via the USB port on the front of your ND5 just to rule out any problem with the streamer itself.

By the way, did you manage to check the version of the streamer's firmware?

If it plays OK from the USB it will indicate it could be a problem with the network as well.   If it does still have the same problem,  it might be something related to AIFF & then the OP should try converting the AIFF to WAV.

I'm listening now  3th album in 192khz aiff and nothing wrong so it's really strange issue.

Sjbabey, firmware version is 4.4.00

Kacper

Are you listening from a USB thumb drive or via your network?

Have you made any changes to your network?

I think its unlikely to be network related, its funny how nearly everyone blames the network first - when most times its not - its not just this forum either - it happens professionally with me as well. Back to this case unless there is a fault with leads or some sort if incompatibility with the Naim Streamer - my suspicion is on the NAS. Can you try an alternate UPnP media server say from a Mac or PC as a test - and serve a file from the PC or Mac instead of the NAS? i think that will either rule out the network and possibly rule in the NAS

Via network. Only what I have done - was resetting device list in DMA compatibility settings in Media Server.

Again agreeing with Simon...you could tell the NAS to perform an AntiVirusEssentials scan now that things are going fine and see if your music streaming fails due to more heavily taxed system resources.

Yes, I have tried from my pc via Asset UPnP one album in 192khz aiff and was no problem at all. I could play with my pc, keep utorrent active during the music was playing and wasn't any disturbance whatsoever.

I will keep on testing, from my mac and the server.

My money's on the streamer.

 I found I had the very same problem, when trying to stream 192 from my QNAP to SBT.

 The reason, I haven’t upgraded to the SBT firmware needed to stream 192.

 It does stream 192. but with intermittent periods of silence.

ok, just happend first time today, the buffer meter was empty  and after couple of seconds the sound came back, wasn't the music but kind of noise which sounds like from TV which has no signal. 

I have sent an email to Synology, let's see what they can say about this problem.

Kacper

Good luck with that, I personally have found them very unresponsive towards accepting of problems when I asked about transcoding gapless.  Anyhow back to your problem,  I have the same DS214 & use the same UPnP - Synology's Media Server,  my system works perfectly & has absolutely no buffer issues with 24/192.  So whats the difference between me & you.   I play WAV, you play AIFF.    I don't use Antivirus as it serves no purpose because I don't connect the NAS directly to www,  so my question to you is why do you need it?.   I only have Media Server & Hyper Backup installed,  what other programs have you installed?   I keep my DSM fully updated, its set to auto-update,  what DSM revision number are you on?  My DSM System Heath widget & the monthly Synology system health report says my DS is working well & my HDD's are in good condition,  what does yours say?

Apart from that I have a pukka gigabit network switch -    

Just to chip in: file format should not be an issue - files are of similar sizes, uncompressed. My NAS stores a mix of WAVs (from rips) and high-res AIFF.

DSM 6.0.2-8451 Update 1. Do you think that any installed application on the server might cause the problems?

I'm also curious what this synology crew will say.

I agree, format shouldn't be a problem... but there is something.

Sometimes those people from synology are asking for permition to access the server remotly .... Let's wait and see if they will be able to help.

I only had one problem with an AIFF file last year  - my UnitiServe would not see becuse there was a dot (.) at the end of a file name.

Following Phil's Harris advice, I changed the file's name and all worked.

I checked some of my albums... all tracks are having dot between name of the track and "aif" - not after

Goedenavond Kacper,  -   6.0.2-8451 is the current s/w

I don't expect any installed application to cause a problem if it comes from (approved by) Synology.   My only thoughts are a lot of unnecessary programs installed that all collectively take up CPU & RAM resources.  Do you really need that Antivirus & what else is taking up space & power ???

I'm still not convinced this is a server problem, but hey I hope to learn something every day & you never know,  my money is still on the network & specifically a switch.    

goedenavond Mike-B,

Yeah, you gave something to think about .. I will check what can be deleted , Antivirus is already off.

cheers,

Kacper

I mentioned that to show that AIFF are generally OK. It your server sees it it can be played.

the good thing is that we seem to be narrowing possible errors down to: NAS or a switch.

Or?...

Have you ever tried taking a specific file that got an interrupted playback on it (when streamed from a NAS) loading it onto a memory stick and playing back using a front USB port?

according the advice from Phil, I will stream the same music files from my mac. The point is, I need to spend for this test maybe couple of hours/albums because the bug is really shabby :-/
