Synology Plex Media Server problems

Server Version#: 1.23.2.4656
Player Version#:
I’ve instaled PMS on m Synology 710+ NAS to replace native media server. Now I see two problems:

  1. server stops after some period of time. I have to login into DSM and manualy start it. Didn’t found anything in logs or setting about idle time, inactivity period etc.
  2. in logs I found
MDE: Moxica and the Horse: Direct Playing due to no transcode profile
Jul 14, 2021 21:10:13.508 [0xf5a2cd90] DEBUG - MDE: Moxica and the Horse: no direct play music profile exists for http/flac/flac
Jul 14, 2021 21:10:13.508 [0xf5a2cd90] DEBUG - Moxica and the Horse - audio.bitrate limitation applies: 746 > 288

What is and why audio.bitrate limitation? How to set it? I want to listen to my FLACs without any downsampling. There are no such settings in Plex setting page (I use web interface).

It might be helpful to post the entire log for the shutdown issue and how are you playing back your FLAC files? Which player? Those together should help get you to an answer from community or devs.

The DS710+ is not officially supported by Plex, as it does not meet the minimum requirements to run Plex Media Server. Both the DS710+ and its Atom D410 CPU were introduced in 2010 and are basically just too old & slow. While Plex Media Server might install and run, it may not be stable given the limitations of the DS710+.

See the NAS Compatibility List support article for a list of supported NAS.

You could run Plex Media Server on a desktop/laptop if you’ve one available. You could leave the media on the NAS and mount the desired shared folders on the PC. This would let you run the Plex server on a more capable system while leaving the media on the NAS.

Running server on other device is not an option.
I attach logs with shutdown event. It seems to be correlated with broken internet connection this time, but other days there was no connection issues when server shut down.
Plex Crash Uploader.log (1.1 KB)
Plex Media Server.1.log (7.2 MB)
Plex Tuner Service.1.log (3.4 KB)

And I do not use transcoding. Server serves as DLNA server :slight_smile: just allowing other devices, like network players or smart TVs to access media libraries. Any decoding work is done by players, so weak CPU doesnt matter. Playing FLAC files makes no more that 9% CPU load, including other processes running.

If supported on your system, the Synology Media Server may be a better fit.

As long as you provide binaries to install Plex on unsupported devices there will be users who install and use it on unsupported devices. That is so simple.

I switched to Plex because Synology’s media server freezes on playing FLAC files and manual restart was required. I was looking for an alternative and Plex looked most promising.

Since Plex isn’t officially supported on that device (the binary for it in the Synology Package Center is likely the Synology hosted “last supported version” not the official Plex supported version) it might be worth working with Synology directly - or their active forums\subreddit - to see about getting the Synology Media Server (DLNA) fixed up. It’s such a simple protocol that doesn’t really require hardly any resources (mostly just a file sharing metadata function) that it really shouldn’t be crashing on you.

I took binaries from official Plex download page, Synology hosted packet was outdated and won’t update so I installed it manually. It’s not DLNA part problem, whole server is switching off. I reviewed logs but I didn’t find obvious error or even event showing shutdown procedure. It just stops.

Are you saying the entire NAS turns off when you’d play a Flac via Synology DLNA/Media Server or that the Media Server package itself would crash? Just wanting to confirm because the former is definitely crazy and would point to broader issues with the NAS and the latter is kinda what I was saying in the first place. I was using “DLNA” and “Media Server” interchangeably.

Either way, both of those instances is odd and maybe Synology folks could help there.

Plex binary in the package center being out of date kinda points to “last supported version” from Synology. Sucks when support is dropped, but for Flac file playback should be able to get something working… either fixing the built in DLNA/Media Server or maybe an alternative media package (like Jellyfin or Emby or other alternatives… not up on audio options myself).

I think it’d be worth the time to hit up Synology community on the native stuff not working.
