streaming from Synology - issue

There is one other observation I can make:

The control point (the iOS or Android app) can also stop / pause and restart the streamer.   It can also instruct the media server to send data packets that the streamer isn't expecting just then.  So it could actually be the app not working correctly or the app loosing it's WiFi connection and then trying to recover, with the recovery interrupting the streamer. - I know this because this use to happen to my system 'til I sorted out the correct settings in my wireless router.  It wasn't a fault in the network, it was just that the default router configuration wasn't suitable for DLNA streaming.

One thing thing that I've noticed which i don't think has been mentioned already is the volume utilization of the Synology NAS.

This can be found in the Resource Meter and I find is generally more of an issue with modern NAS drives than CPU or memory utilization.

Good tip Music247,  I have the same Synology DS214 model & Media Server UPnP as Kacper.    I tend to look at the Resource Monitor on odd occasions just to see how its all going & in the all combined screen you can see it all in one view.  I've never seen the volume much higher than 1% ..........  this is Hotel California 24/192 WAV from the startup sequence peak

Mike, I think he was referring to Volume Utilisation in the Storage Monitor - i.e. disk occupancy.

This should never be allowed to exceed 80%, and ideally should be kept below 70% to allow the anti-fragmentation algorithms to work efficiently.

This is only true if someone does many updates / deletes / inserts.

Otherwise it does not matter, and since a NAS used for music / movies is not a place where old data gets updated / deleted it is less of a worry.

He might well be thinking that Huge,  but the Resource Monitor (Meter as he called it) is the one I show in the pic..   & that is labelled as Volume Utilization.    The Storage Manager is just labelled Volume & shows HDD storage utilization & status.

We don't know if he uses his NAS for general storage as well as for media streaming.

As i understand it Volume Utilization in Resource Monitor indicates how hard the volume of the NAS is having to work at a given time.

This should be extremely low as explained by Mike-B. However if the volume is heavily multi tasking then this can easily go to nearer 100%. If this was the issue then creating a second dedicated volume for the music store could be the solution.

It's just something else really simple to keep an eye on.

U-Torrent could certainly be causing heavy volume utilization. Reducing the number of consecutive uploads/downloads may be the answer.

Hi guys,

 I gave the synology support team access to my server, they did some research and-

"After some investigation, we suspected it could be one issue we are tracing.

Could we have your remote to apply a debugging tool?

That would just need to restart AFP and no harm to data." - something like that.

Because there was also other things like connection issue with Finder (OS) - (maybe those two problems are common)

When I'm back at home will try and see if it's working properly.

The best thing for a NAS drive to be used as a Media Server (a Pseudo-Real-Time task) is to use it as a Media server, and not clutter it up with non-real-time tasks.  If you want a NAS for those, use a second NAS that: One that isn't trying to do time critical tasks at the same time.

They are Apple/Mac features ........     

Just as a side note i don't believe you need to use AFP if you are running OSX Mavericks or higher. SMB protocol should work better.

yesterday I have created other "question key" regarding streaming 192 khz aiff issue, for that question i didn't get response yet. Usually it takes up to 3 days.

Those results are as expected and almost identical to Mike-Bs results, which suggests that the problem lies elsewhere.

All the resource monitor graphs look good to me including the network one. Do the graphs still look like this when you get the drop outs?

Have you tried restarting the NAS?

If you are transcoding to WAV have you tried turning this off?

Do you get the drop outs if you stream native 24/192 FLAC or WAV files?

..... 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

Any luck with this - I think it will cut to the chase quite quickly. Your static noise episode sounds disconcerting however

yes, I have done everything, no transcoding.

The last one it is actually a good question.... didn't recognize any problems with flac - only with aiff (wav I don't have it), also no probles with DSD - until now.

But it seems the bug is really tricky, yesterday I could listen almost 3 hours and nothing and almost in the end of 3th album "bam" - happend.

If the issue will keep continue with out any hope for curing this problem I will start buying wav or flac ( happily I don't have much albums in 192khz aiff)

I appreciate your help guys.

Kacper,  if the problem is only with AIFF,  why not just convert to FLAC or WAV & forget it.  I have bought in AIFF as sometimes its all thats available,  but straight away I convert to WAV with dBpoweramp.    If you decide go to FLAC - & that is many peoples prefered codec - its better if you transcode as Naim like to be fed WAV,  in that case you need Minimserver (plus Java8) as Synology do a bad job transcoding with Media Server.

yes, you are right. Next time I will try with wav. Is there any settings inside of minimserver available for users, like for example changing folder names etc?

If you change to WAV you don't need to move to Minimserver,  its your choice,   but Synology's Media Server is faultless with WAV;  there is no need to transcode as its already WAV,   & it plays gapless WAV albums perfectly.   Minimserver is the best for FLAC, ALAC & AIFF when you want to transcode into WAV & to transcode gapless.  

I have never tried to change folder names in the Synology,   you can do it in DSM File View,  but I feel more confident (because of familiarity) to change folder names & restructure/move folders in Windows Explorer (not sure what its called in Apple/Mac)

Still no update on this? We appear without it to be going around in circles?

next time I will purchase something in wav, usually I do "shopping" at HDtracks and they have multiple formats available including wav.

Well with media server from synology you can personalize some settings... for example DMA menu language or DMA menu style.
