SU connected to PC

Your USB output would need to go through some sort of converter (such as Hiface2)

That's a little confusing.

If you're using UPnP, the SU won't see the Vaio's hard disk, it'll see the UPnP Media Server from the Windows OS and not see the hard disk.

How are you controlling the SU?  Often it's the control app that's not seeing the Media Server rather than the SU.  Sometimes the WiFi network can be a bit shaky with the UPnP protocols, in which case it's often the WiFi broadband router config that's the real problem.

Connecting the PC and the SU using wired Ethernet via a switch will usually increase the reliability of the connection, and decrease the reliance on the vagaries of WiFi.

Naim App with my Ipad, very bad service, often it is impossible to perform music for this I would use a cable

M2Tech Hiface" looks interesting, I read now some articles on the web and it sound great

Thank's 

How is your network connected?

I suspect that your problems are more to do with the network configuration than with the SU or the PC.

My network setup is served by a modem router TPlink TDW 8970 - download speed 15.80 Mbps - Upload speed 0.70 Mbps - Ping 26 ms  just tested now with speedtest by Ookla . Spotify  with SU works very well, streaming movies even in HD without problems so what is wrong with the UPnP function that even now can not detect the musics files on my PC.

this afternoon has only worked once then it was no possible to use it

I suspect that the issues you are having relate to your Local Network (LAN) which is separate from your connection to the Internet and the download etc. speed figures you've quoted. How are your computer and other devices on the network connected? The ideal way is to connect via Ethernet cable and to connect the router to a switch to which your computer and other devices should be connected via Ethernet cable as routers are not ideal as hubs for switching between network devices.

All my devices are connected in WI FI as my SU , I do not use ethernet cables, everything work so good: I can understand that via Ethernet cable is the best way but the only problem that I have is with the UPnP function and therefore would prefer to settle down with a USB cable connected it to the PC/SU only when I want to listen to music  from my PC and free up my living room from additional wiring such as Ethernet cables.

It would be appreciated an Naim update that would make compatible the USB input on the front panel with Windows PC

Anto, what UPnP server software do you have installed on your computer ? A lot of forum members use Minimserver which is free or Asset UPnP both of which will run on a Windows computer.

Do your UPnP servers appear and show your music files on your Naim app?

Trying to connect everything via WiFi is asking for intermittent trouble.

If you can connect the PC to the SU via USB, then why can get a switch and connect them using an Ethernet cable?  You can always unplug the Ethernet cable from the PC (I assume it's actually a laptop) when you want to move it around.  Changing to wired connection is the first step to getting a reliable system.

The USB on the front is the USB controller, not a peripheral device that can be controlled.  It simply isn't the right type of hardware to be controlled by a PC.

I have not installed anything in particular, my music files are stored in the music folder and when the UPnP works in Naim app display my windows music folder, I'm sorry but I'm not very aware of this topic, I started a few months ago, since I bought my SU.

I want to follow your suggestion about the Minimserver I hope to resolve the problem. thanks for your help.

I'm sure the problem isn't the type of UPnP server you are using, I think it's the network configuration.

My modem router is placed away from the SU, someone invented the WI fi just to avoid to complicate things

when it is possible.

Unfortunately WiFi was invented for network operation NOT for real-time streaming. 

Huge,

It seems to me that Anto either hasn't installed any UPnP software on his computer or, if he has, he hasn't configured it correctly.

sjbabbey,

The problem is intermittent, he says that sometimes it doesn't connect: That's much more likely to be network than OS config.

All Windows OSs have had a pre-configured UPnP server since Windows 7.  When you put files in the Music folder they're automatically made available through UPnP.

Maybe I'm not an expert in these matters but I'm asking why it is compatible with Ipad, Iphone and Ipod onòy, and not an Android device: I suspect instead that are marketing choices rather.

There are much cheaper amps out there that have a USB input compatible with PC, why Naim has not provided a similar feature?

I think it was a conscious market and technology strategy for Naim to be Apple certified, and having the USB input and control software able to access content from iDevices was not "usual" at the time Naim introduced it. The input is not an asynchronous USB input, however: it works with memory keys, external hard drives, and iOS devices. The Naim asynchronous DAC is the V1, and that's its main gig (ie the V1 works with USB outputs from computers, but it isn't a streamer). At the moment, afaik, Naim does not have a device that does both. 

To your point about cheaper solutions, that's also likely a market and technology strategy decision by Naim: they have chosen to implement top quality solutions even if it means foregoing convenience to maintain sound quality. If you want an inexpensive asynchronous DAC for use with the USB output from your laptop, you can get one and connect it to an analog input on your Naim gear...but that wasn't part of their philosophy and so it's not part of their approach. Not what you might want to hear, I guess, but that's how I interpret things.

Point taken, Huge and I think it may well be a local network issue also. Am I correct in thinking that Windows player now supports playback of flac files or is this still a potential issue?

I don't know about FLAC support now, it wasn't native to Windows 7, but there was a free codec available (after all that's why it's called FLAC).

I haven't used Windows Media Player with Windows 8 or 10 as Microsoft removed DLNA 1.5 support from the underlying libraries.

Huge and Sjbabbey,

I would refer you what I found out about this problem: It does not seem to be a problem between the SU and my laptop.

when I select the UPnP feature I can detect my music files on the SU display and I can run it using the SU remote control; uncomfortable but however it works.

Then the real problem seem not be my network configuration rather the Naim app in IOs with my Ipad. I confirm that it does not work even with my Android smartphone in which I installed the same Naim app.

More precisely, only it works sometimes.

Regards

Flac  is supported by Windwos Media Player  that it supports the majority of encodings: only the DSD 64 are not supported .

I have downloaded many DSD 64 tracks and I had to transfer them to memory keys to listen on SU

In that case you may have the same problem that I had.

It was caused by the configuration of my WiFi router not passing on the DLNA network discovery packets that the app has to use to find the streamer and the music server.  The filter is called "IGMP Snooping"; disabling this in the router's configuration may make this more reliable - it's certainly worth trying.

IGMP and its version is the multicast routing protocol used..and multicast IP addressing can be used by certain discovery packets  Snooping is when advanced switches or router switch ports monitor the IGMP and learn what is happening on the network with regard to multicast groups so as to switch the multicast data efficiently to the correct switch port. However sometimes the multicast routing protocol version used is not compatible with the snooping software used on the switch and so the switch doesn't correctly learn which ports are belonging to which multicast groups..this means devices can disappear from groups.. or in this case devices are unable to be discovered.. The answer to this software interoperability issue can be to disable snooping or use a basic unmanaged switch which because it hasn't the processing power to handle multicast group functionality simply blindly broadcasts multicast addressed packets to all ports. For small home networks, and certainly for UPnP discovery this is unlikely to be an issue.

Simon

As suggested by Sjbabbey I installed and configured Minimserver,  it works at the moment but I also pleasantly discovered that Minim server support DSD 64 codec,  while it was not possible with the UPnP provided by Widows Media Player.
