Internet radio issue with "Audiophile Baroque"

I have just found it & am getting it at 100% buffer for the last 20 minutes ........  to check we have the same station, I have a family of stations called "Audiophile" tat are located in Greece (?)

But you are on the beta test team so have the same (latest) firmware, Maybe I have a link that you do not have,  try to power cycle (switch off & on) to re-establish your NDX to re-establish the vTuner links,  it might change something & worth a try. 

DrPo, this can happen because the latency or round trip delay across the Internet has increased, most likely temporarily.

Web radio uses TCP for the data transport and uses buffers at both ends. The larger the round trip delay the larger the buffers required. I have across this before where perhaps the Naim buffers haven't been able to increase sufficiently. On a PC/ Mac these buffers can grow quite large and is usually not an issue. I can't be categoric this is definitely the cause, but the symptoms fit.. and as you say it is nothing to do with local Internet access speed. if you have the know-how, a local web caching proxy server may circumvent the issue.

thanks both. The station is streaming out of Greece (where I also happen to be located but being an internet station is I would guess irrelevant :-) and in fact there are 3 siblings (Baroque, Classical, Jazz); i just checked and all 3 of them have the same issue with NDX. I hesitate to power off/on as despite all the fixes I still get the "fault 36" message requiring a lot of power cycles to disappear... as for Simon's idea I like and understand the concept but not sure I can implement it. I may play later this evening with the firmware versions ...

I'm trying it now, and it seems fine, with 100% buffer. Quite why a Baroque station is playing Mozart though......

All, thanks for your suggestions. Firmware update, power off/on, router restart were all tried, alas to no avail. I will try to check the same on my local NAIM distributor's NDX over the weekend. I don't have access to the 320 BBC stations and I am not aware of many 320kbps streaming classical stations (I listen also to the Dutch AVRO ones but they are lower resolution) so missing out on the 3 "Audiophile" stations (Internet, no adds) is really an inconvenience, getting rid of which I would be happy to accept good old Amadeus for "Baroque" (fair point by HH) :-)

I've been listening to this station off and on over the last few months, and never had your problem on Superuniti. They do have a rather flexible definition of Baroque, but I don't care, the more Mozart the better!

Here (Germany, Berlin) no problems with "Audiophille Baroque" via MPD running on a Debian system. If you can succesfully process the stream using another client it's an NDX problem I guess. Good luck, nbpf

Checked with my NAIM distributor, also has no issue. So it's either my internet connection (unlikely, 50kbps VDSL) or the unit. Thanks all for your input. In fact I was wondering today if we have on the  forum a thread with recommended internet stations. There may be thousands of them, but apparently only a handful offer 320 quality and there is unfortunately no easy way to filter them out.

DrPo, it could still be your ISP or the route your ISP uses causing TCP flow issues with your NDX. Perhaps you could use a 4G connection via smartphone temporarily or use a neighboughs wifi access on a different ISP to see if the issue goes.

As I said earlier there is a lot more to continuous throughput than access 'speed'. If the the TCP parameters in the NDX network stack are slightly constrained then this can become more acute. I have seen this behaviour before on my NDX, but not recently.

DrPo,   if your dealer has no probs,  then that proves it is available in Greece & there should be no reason why you can't get it. 

Simon's suggestion about using a neighbor's wifi is worth a try, provided they have a different ISP.   

You said you rebooted after the latest f/w (beta 4.2.8) was installed & also rebooted the router,  I would now be tempted to try a factory reset - yes its a pain as it means resetting all your preferences, but it costs nothing other than your time.  Then if that changes nothing, reboot again, but only the NDX & leave it off a few minutes before restarting -  after that,  I'm out of ideas.  

DrPro, this is my favorite station, too, and over the last year or so I posted several threads here on the story of my struggles trying to get it to play on ND5XS. I even wrote to Naim support who, after several emails exchanged, finally told me it's not their problem.

This station plays perfectly on 3 other streamers I have at home: 2 inexpensive (by Naim standards) Denon units and an old Iphone 4. So it's NOT a station problem.

The only solution for playing it on Naim gear is to use an external music server (I use minimserver running on my Synology NAS) and building a playlist. It's described in my thread on this forum a few months ago.

i've asked vTuner to investigate

well, apart from one week whereupon I had the buffering issue described on this thread everything was OK both on my original UnitiLite and now on the NDX. It seems to work  after the "trick" of deleting from favorites then selecting again...

do you know of a similar iOs or windows program? My solution so far was to select in vtuner a genre or location then list the stations by bandwith and after identifying candidates try to install them on the streamer.
