Synology NAS high res music - help

Hi Paul

Are you using the NAS as a upnp server. I have a 212j in this way without issue, so maybe able to help. If your using it in another manner then im sure some one else will be along shortly.

Hi Foxman,

Thanks for quick reply.  To be honest I am not sure what I am using it for.  I have a Unitiserve, and want to stream HiRes from the NAS. Both are hard wired to my router. I am not sure whether or not this is UPnP?  The music does play, but not in high res.

I have found one setting in the NAS to " enable transcoding" to other formats, and I have tried with this setting enabled and disabled.  The result is the same,standard res music.  There is no issue with the music files, they play fine when a put them on a USB stick and plug this into the Unitiserve.

Cheers, 

Paul

Sorry for the obvious question, but why do you want you want to stream hi-res from the NAS when the UnitiServe already does a fine job?

If you are running DSM ver above 3.2 then transcoding does not work on Syn NAS for Hi-Def. But this is only needed if you are converting flac to wav.

Are you using the built in "media server" app on the NAS. If you install this it will create 3 folders one of which is called "music". All you do is copy your music into this folder and your streamer should pick it up. I have this connected to an ND5 without any issues

Paul, I assume that your uServe is connected to your NAS via a DC-1 cable or similar?

In this setup, the NAS is merely external storage for the uServe (providing "music shares") -- it is NOT acting as a server and is not using its "Media Server" app.  There are no relevant settings in that Synology DSM interface that you don't like   This is how my Synology212j / uServe / Naim DAC has been set up over the past year, and the hd light on the DAC does light up when hi res downloads are played.

Other settings on the NAS apps shouldn't make a difference, as the apps aren't used in this mode.  Just be sure that everything is set up this way -- that the folders on the NAS are being viewed as "shares" by the uServe.  You can look at the Network Shares via the web interface.

Hope this helps.

Hi Folks,

Thanks for the replies, but I get more confused with each reply - just goes to show my ignorance of the whole business of digital audio.

I have high res FLAC files which are stored in a folder on the NAS which the Unitiserve sees as a "device". Both the US and the NAS areconnected by Ethernet to my router.

All I want to do is play the files (located on my NAS) using the Unitiserve. Whether this is " streaming " or not I don't know. The files do play on the US, but not at high res. So there is no connectivity issue.

Thanks,

Paul

Paul,

Presumably you went through the US web app and set up the Network Share?

If YES:

You are not streaming the data, a la NDX etc via UPNP.

The directory is accessed via SMB as a share by the US.

....and you state have connectivity.

As you have played the flac as HiDef from USB you are satisfied these ARE HiDef files (>= 9624).

My immediate thought would be to take one of your HiDef files, un-flac it and access the WAV file and see if that plays as HiDef.

M

M,

Have checked it out,indeed the folder on the NAS which contains the hi-res music is seen by the US as a Network Share and it is enabled - confirmed by the little green light.

Sorry to appear dumb, but how would I convert the FLAC files to .WAV ?

I am sure that it some setting buried,somewhere on tbelieved NAS, but I can't find it.

Cheers, 

Paul

For what you've paid, your dealer should come to your house and help you.

Paul how are you connecting your uServe to your Naim DAC?

Am I right -- that with the usb stick plugged into the back of the uServe the DAC's hi res light went on, but when played from the NAS "share" it doesn't go on?

H Bart,

Exactly right, high def light on when played from USB, but no high res light when same files arevplayed from NAS. The DAC is connected to US with the Naim DC1 (or is it BC1 ?) co-ax cable. Would be great if the dealer could sort it, but I have since moved country and there is no naim dealer in the country I live. The files are FLAC. If I look at the files on the NAS using my Mac, this confirms that they are FLAC format, and by the file might high res.

Not sure where to go next.

Paul

Paul,

Download and install flac.

Pull a flac file onto your PC.

Unflac it, either through the GUI or on the command line.

Upload the WAV file.

Rescan your shares.

M

Might work but shouldn't be needed.  IMHO something is wrong somewhere . . . the question is where.  What Paul is trying to do DOES work for folks, just not him.

Bart,

This is how I would troubleshoot the issue.

Address and isolate potential issues.

We can all postulate.

M

Agreed; he has to start trying one variable at a time. 

Bart, M,

Thanks - will try out wav files playback this weekend and report back.

Presumably if wav files play in high res without problem, then I have some sort of transcoding problem with the NAS ?

Thanks, Paul

Transcoding is not occurring, it would only be happening if you were using a streaming client (NDS, NDX, ND5XS, Uniti, etc) from the Synology NAS UpNP server and you had setup its UpNP server function to do so - but you are not.

The UnitiServe is a server that can handily index music held on a network share (SMB share to be precise)...not sure is you have an SSD serve or one with on board storage but the function is the same. The synology is acting as a file server only when used with a serve and it's UpNP functions have no effect on its file server functions.

The serve does not act as a streaming client even if there are other UpNP servers are on the same network.

Purehifi,

Thanks - after your post I did some more investigation and I am now more bewildered than ever. Out of some 30 HiRes albums on the NAS, I have now discovered that only 2 will not play in in high res (they do play, but at standard res, as per the nDAC light status). The two albums are both early Stones albums, and play fine off the USB stick plugged into the Unitiserve (hard disk version), but only in standardbdefinitionmfrom the NAS.

So.....thinking that the files may somehow be corrupted,  I deleted the files from the NAS, and then recopied them across from the USB stick.  Result - no change ! When  I look at the files on the NAS, the offending Stones albums are definitely FLAC format, like all the rest of my high-res music, and by the file sizes they are definitely high res.

I am utterly bewildered by this, but can't waste any more time on it. Isn't digital audio fickle ?

Mick will have to stay on the USB stick.

Cheers, Paul

Paul -- that was some good troubleshooting.  It's nice that it doesn't happen with every file . . . but why just those two??  That's a head-scratcher.
