JPLAYStreamer(JPLAY6 RC1)/MinimServer/BubbleUPnP

JPLAYStreamer(JPLAY6 RC1)/MinimServer/BubbleUPnP
I am running JPLAYStreamer(JPLAY6 RC1)/MinimServer/BubbleUPnP. There seems to be connectivity issues. The setup will largely work but when I click on the ‘Playing Now’ screen on BubbleUPnP, I get no album or track details, no cover art and no elapsed time/time remaining clock. At JPLAY Forum I am being advised that this is likely to be a network issue but all of my other networked PCs and printer/scanner are clearly visible on the network and work fine. If I install Kazoo (Windows Version) on the same laptop as I am using for JPLAYStreamer(JPLAY6 RC1)/MinimServer/BubbleUPnP, everything works fine and I can remote control from another laptop or desktop PC using TeamViewer.

This sounds like a problem with the way your network is transmitting multicast messages between your laptop and the Android device running BubbleUPnP. What router do you have and does this router provide the wireless signal for the Android device? Also, does the laptop running JPLAYStreamer and MinimServer connect to the router using a wired or wireless connection?

I have a BT HomeHub4:

This router provides the signal for my Android tablet. My laptop running JPLAYStreamer and MinimServer connects to this router using Ethernet cable.

There is a known issue with 5 GHz wireless connections to the Home Hub 4 (see this thread). The solution is to make sure all wireless devices connect to the Home Hub 4 via the 2.4 GHz band.

RE: JPLAYStreamer(JPLAY6 RC1)/MinimServer/BubbleUPnP
Thanks Simon. I was unaware that the issue with 5GHz on BT Home Hub was a known issue but I think I discovered that for myself. I hasten to add that I have no tehcnical knowledge on networking whatsoever. I just folow the instructions of others!

I posted the following on the JPLAY Forum yesterday:

Still haven't cracked it yet. Sometimes I can browse my collection and play music. At other times I can't play a thing.

Having tried out a few things, it would seem reasonable to assume that the problem might lie with network communication with JPLAYStreamer. I have problems whether I use BubbleUPnP on Android Tablet or Kazoo/Kinsky on iPad. I will stick with BubbleUPnP as that is the one I would like to get working. I like the UI! If I select the local renderer, playback through my Android tablet works reliably. When I select JPLAYStreamer as the renderer of choice, then playback is much less reliable. Sometimes a simple restart of JPLAYStreamer in the Task Manager solves the problem. At other times, rebooting my single PC or restarting BubbleUPnP will cure the problem. This evening, trying to get any playback was akin to trying to raise the dead! I just couldn't get any response. if I try a couple of hours later, then it is just as likely as not to work reliably. The fact that the problems occus when JPLAYStreamer is selected would perhaps account for the fact that playback reliability is restricted when using Kazoo on my iPad. It looks very much like network communication with JPLAYStreamer is the issue. Installing the Windows version of Kazoo on my single PC and controlling remotely with teamViewer works a treat but there is a slight degredation in sound quality when using this option. Would experimenting with my JPLAY settings make reliable JPLAYStreamer playback more likely?

Josef recommended that I restrict my router to the 5GHz band and while this suggestion seems appropriate, it actualy brought about the least reliable performance experienced. I now have my router restricted to 2.4GHz and while one might expect this to work, it seems to give a higher level of reliability. Neither band provides full reliability.

It is often the case that when trying to play an album or track, it will transfer to the playing stage and will display track details and cover art in the 'Now Playing' screen of BubbleUPnP. It just won't play back with JPLAYStreamer selected as the renderer.

A friend of mine who is very clued up on networking feels sure that it is a networking issue. He he said he will come over and take a look when he has time. he mentioned something about ports in the router ... It made no sense to me!

In the meantime and pending my networking friend's arrival, is there anything else I could try or anything that I might have missed?"


Marcin (Co-author of JPLAY with Josef) responded as follows:

Yes, network connection is dropping thats why control point loose jplaystreamer renderer. You can install inssider and check if there is not too much networks on the same channel in your area.

Apologies if posting all this is unhelpful. I figured that the more information I could provide, the greater the chance of someone more knowledgeable than me being able to provide a solution.

As always ... With thanks

From the information you posted, it sounds like there might be two different network problems:

1) The Home Hub 4 has a problem with miulticast over 5 GHz. The solution is to completely avoid the 5 GHz band for audio traffic.

2) There might be a problem with overlapping nearby channels on the 2.4 GHz band that is causing unreliable performance in your location. If this is the problem, the solution is to use inSSIDer to find an empty 2.4 GHz channel as Marcin has suggested and switch to it.

If doing the above doesn't solve the problem, there might be some other network issue and it would require someone with specialist network knowledge (your friend) to debug it.

This would happen if the format of the stream you're trying to play isn't WAV because JPLAYStreamer is limited to playing WAV streams only. What format does BubbleUPnP show on its Now Playing screen?

RE: JPLAYStreamer(JPLAY6 RC1)/MinimServer/BubbleUPnP
Thanks for the very prompt reply Simon. I am now aware of the limitations of the Home Hub 4. Another friend recommended it to me as a dual band router and said that it is optimised to work with BT Internet. It would appear that it is not optimised to work over 5GHz! My friend told me this so I disabled 5GHz capability and reveretd solely to 2.4GHz. This didn't solve my problem. I couldn't get Inssider to run on Windows 2012 R2 Server. It crashed on startup and although I tried Windows 7 and Windows 8 compatibility modes, it was having none of it.

I found a very positive review WiFi Analyzer, which I installed on my Android tablet. That worked fine and suggested that the optimum channels for me were 11,12, 13. My router was currently working on auto to find the best channel. When i went into router settings, it was running on Channel 1 so I changed the settings so that the router now runs exlusively on Channel 11.

I have had that running for the past 40 minutes. I can view my album collection and change albums without any problems although, apart from the first album that I played, the Now Playing screen is not functioning at all. On the single occasion that it did work, it gave the format as PCM and correctly identified the resolution at 16/44. I am able to view the tracks on an album in the Library view and I can change track. If I do this, playback stops as soon as the selected track has finished. I would expect this as it appears that in Library view, any track selected is not added to the playlist. Although I can play an entire album by selecting it and clikc the Play button at the top of the screen, I don't get the bar near the bottom of the Library screen, confirming the track that I am playing.

Maybe I will try changing channel again in an attempt to get the Now Playing screen functional.

UPDATE: I have been trying different channels and monitoring with WiFi Analyzer on my Android tablet. The app recommends channels that I should use but as soon as I change to one of those channels, the app immediately drops its rating for the channel and recommends something else! When I change channel, it seems that my neighbours channels change to the same as the one that I am trying to use. I'll now change to automatic setting and monitor that

In the 2.4 GHz band, there are only three non-overlapping channels. These are channels 1, 6 and 11. It isn't a good idea to use any other channel because the frequencies used by this channel will overlap with either 1, 6 or 11.

The 5 GHz band doesn't have this problem. In the 5 GHz band, all channels are non-overlapping.

RE: JPLAYStreamer(JPLAY6 RC1)/MinimServer/BubbleUPnP
I think I'm starting to get this ... It seems best, as a rule of thumb, to avoid overlapping channels so on 2.4GHz this leaves a choice of 1, 6 and 11. I didn't have much luck on Channel 1 as this is the channel that most of my neighbours are using. I will try 6 and 11 at some point.

I have setup my router aacording to the advice on this webpage:

http://www.pcadvisor.co.uk/how-to/broadb...mum-speed/

My devices now see two networks, one of which is dedicated to 5GHz. I have also disabled smart setup. Whether or not it might make a difference I don't know. At present, everything is working. Playback is being activated and the Now Playing screen is displaying and updating correctly.

Am I right in assuming that to connect at 5GHz would be the best option ... but now with the BT Home Hub 4?

I believe it's the opposite. The Home Hub has an issue with multicast over 5 GHz, so it would be best to connect all your devices to the 2.4 GHz network on the least congested channel out of 1, 6 and 11.

With your current working setup, are your other devices connecting using the 2.4 GHz network name or the 5 GHz network name?
