Minimserver unable to stream 192kHz on DSM 5

Posted by: Sorren on 12 March 2014

Hi everyone. I'm hoping someone on here can help.

I have been using Minimserver (and Minimstreamer) for a few months now on my Synology DS212j and haven't had any problems. Since updating to version 5 of DSM last night I can no longer stream 24/192 music as there are frequent pauses/drop outs. 24/96 music streams fine and the built in server on the Synology is also unable to stream 24/192 files without dropouts.

I'm sure it's not the network as firstly it worked OK before the update and secondly the UQ2 and NAS are connected using CAT7 cable through a gigabit switch so hires streaming shouldn't be a problem.

Does anyone have any idea what might be causing this problem and maybe have a work around? Minim was also updated last night but as Synology's server also displays this problem I don't think it's a fault with Minim. Nothing in the NAS or Minim logs jumps out at me so ...

Any help would be greatly appreciated.

Perhaps a change in the Ethernet frame size?

I see that you have already done what I would have suggested. (post on the MinimStreamer forum). Please keep us informed if you get an answer there.

Have you also raised a support request with Synology?

As Bananahead said this sounds most likely to be some sort of interaction between your NAS operating system and UPnP DLNA server program with respect to I/O that was introduced with the upgrade and best raise on their respective support channels.

DSM 5 beta, I think.

While I often am anxious to get the latest, I passed on the 5 beta a while ago and would rather the bugs be worked out before I adopt. In this world of streaming, "If it aint broke don't fix it" really applies. I understand why folks can be loathe to update when something works.

DSM5 is out of beta now

DSM5 also now supports streaming DSD. Not that there are any Naim devices to receive it.

I am running dsm 5 build 4458 and playing 192, transcoding from flac to wav with no drop outs. However, the cpu is at 99% on my 212j and any other load on the 212 does cause drop outs.

Thank's for your input everyone. We had a power cut this morning and when everything came back up the 24/192s are playing as normal with a CPU load of 40-55% while transcoding FLAC to WAV so I have no idea what was going on last night. I restarted the NAS box several times while trying to get it working so it shouldn't be that.

Anyway all working now so I'm happy (for the moment anyway).
