Streaming (audio) issues
« on: September 12, 2019, 10:10 »
Just thought it would be good to raise this for information and sharing.

I am using a Synology DS214play NAS and streams to my Naim NDS with a wired connection throughout. I have faced numerous problems before but generally it is working fine.

However, once in a while, the NAS will fail to 'serve' the files to the NDS and I cant see the files from the phone or the NDS screen.

So what I will have to do is to go into the Synology assistant and uninstall and reinstall the "Media Server".

Initially when I couldnt find out what was wrong, it drove me nuts. But just curious, why would this happen, i.e. why would the "media server fail"? Is there a way to prevent this from happening?

Leave the media server as is. Install MinimServer for music streaming to DLNA streamer.

Yes, I stream via Synology NAS as well and use Minimserver.  Took me some time to realize that Media Server must be running.

A long time ago, I used minimserver. I cant remember why, but I actually prefered the use of the media server. Somehow I remembered using the minimserver was "troublesome".

Just curious. Before reinstalling, did you try re-indexing?

Now for my next problem. Not so much a problem with streaming per se, but part of the process.

So I have to rip my CDs and copy the files over to my NAS. So what I do is I will rip the CDs with my Sony notebook that comes with a built in CD ROM. Then I will transfer the files over to the external HDD then plug the HDD into the NAS via USB.

What used to happen was that I can use my Windows notebook to see both the NAS and the HDD via Windows Explorer and I could copy the files over. Slow, but manageable. Then after a while, there were times my notebook just cannot ‘see’ the NAS. I can still see it in the network (as in when I double click on it, it will open the Synology Assistant). However, the notebook cannot see the NAS like a drive. I have to reboot the notebook a few times and then sometimes it will see the NAS like a drive.

However, recently, it totally cant see the NAS like a drive. So the only way for me to copy over the files from the HDD was to go through the ‘File Station’ in the synology assistant which is a total PITA. It is super laggy and I cannot (or don’t know how to) open 2 File Stations side by side. It was total disaster when I want to copy my Chinese files (which I name in Chinese chars) over to the NAS, cos I wont know if e.g. 李is before or after 陈, if you know what I mean. And scrolling through the folders using the file station was super laggy.


Then I thought this is all because my notebook was accessing the NAS wirelessly through my home network. My NAS is connected to a CISCO switch, and so I connected to the notebook I am using to the switch as well using a LAN cable. So NOW, I can see the NAS as a drive in Windows Explorer, BUT… I can only read files from the NAS but I cannot copy files into the NAS (seems like no WRITE ACESS). I was totally about to give up. I thought must be some dumb setting in my NAS.

So as a final resort, I thought why not try using my pretty old macbook air and see how it does.

AND GUESS WHAT… using the macbook air is a treat. The Finder just sees the NAS a driver and the scrolling through the folders is a total breeze. So now I just open 2 Finders, one for the NAS, the other for the HDD and just copy and paste over.

So it is NOT a problem with the NAS’ settings?

Any clues what is happening, guys?

Media Indexing

I had not used NAS for a long time. Not sure if the following info is correct.

Can try this link: https://www.synology.com/th-th/knowledgebase/DSM/help/DSM/AdminCenter/application_mediaindexservice_general

In addition, not sure if this is useful:

Drive mapping

The solution maybe dependent on Window version.

Another other reason UPnP servers can "disappear" is to do with the Ethernet switch doing funky stuff with multicast traffic (which UPnP uses to advertise its availability to UPnP renders).

Whats your wired LAN network like? There are a couple of UPnP diagnostic tools that can help you trace what's really going on, like "UPnP Analyzer" on the Mac... I doubt your root problem is the "Media Server" software crashing... could be, but I doubt it.  ;)

Both my SingTel router and NAS are connected to a CISCO switch. From the switch, it is connected to a wall LAN point which is wired to my hifi room. From the hifi room, there is another wall LAN point which is connected to my Naim streamer.

However, I faced the exact same problems before I added the switch, i.e. the NAS was connected to the singtel router and from the singtel router to the wall LAN point.

And are the "wall LAN" interface passive cables or is there anything active there?

Your setup sounds pretty straight forward, but I'm pretty sure the Synology Media Server isn't that buggy... I've got a Synology at home, I'll give the Media Server a spin when I get back to Singapore this weekend and see if I notice anything ;)

By the way, are you running the latest Synology diskstation manager/OS?

Actually, its difficult to pinpoint what is the exact cause or causes. There maybe one or even more causes that cause the phenomenon that TS is experiencing. So, the solution may not be just be one single solution. For example, the first "non-responsive" event maybe due to cause A, while the second "non-responsive" event maybe due to cause B, so on and so forth. So each event may require a different solution. But hopefully there is only one cause and thus only one solution is required.

So one way of solving it is to gather possible solutions and then having TS trying it when it occurs. So its better to have more ideas/solutions. He can start trying the simpler and free solutions, then progress with more complicated and non-free solution.

Definitely agree with you that Synology is relatively trouble-free.

If yes, then how?

...

I gave Media Server a try… I have to take my words back :P... Synology’s Media Server is definitely a little dodgy, behaves inconsistently and doesn’t always respond to SSDP M-SEARCH broadcast. That said, once I changed its “SSDP advertisement interval” down to 30 seconds (from its default of 920), it started to behave more predictably.

Give it a try; from “Package Center”, with Media Server running, click on [Open], and change “SSDP advertisement..” down to 30;



In case it craps out again, Stopping and Restarting the Media Server should work rather than having to uninstall and reinstall. Just make sure once you restart it, it’s actually running (I noticed it doesn’t always seem to run). You can verify it through Task Manager, and look for Media Server and it’s two processes, “dms” and “lighttd”



By the way, be sure your Cisco Switch is not blocking multicast traffic, and specifically that UDP port 1900 is open (used by UPnP to search and advertise UPnP services).

On your other problem of accessing the NAS from Windows; assuming your Synology is properly running SMB and/or NFS file services - they’re on by default unless you stopped them, just make sure from Control-Panel -> File Services, that “SMB” and “NFS” are selected - then the problem is likely your Windows Network Discovery & Sharing settings… Google how to turn on Network Discovery on your version of Windows. Once you do that, from Windows Explorer, you should be able explore “\\Your-NAS-IP-Address” and it’ll pop-up a window for your NAS login credentials, and then straight to your NAS shared folders from within Explorer.

Good luck!  ;)

A couple of ways, but the simplest “dirty” way is via Audio Hijack on a Mac… Record the digital output stream (even MQA decoded streams ;));
