Disappearing OH renderer

[Marmite Sandwich]

Hi,

Been a long-time user of all bubble software and they are great :-)

I am now trialling a new renderer - Cambridge Audio CXNv2, which does not support OpenHome, so I have set it up in the Bubble Server which is running in Windows (0.9-update40). The problem is, it doesn't show up in all control points all the time. The worst offending control point is BubbleUPnP on Android, where it sometimes shows up, sometimes not. Other OH renderers (via the server) show up reliably, but not the CXN. It appears in Android/Kazoo and Windows/UPPlay, and one instance of Android BubbleUPnP, which is running constantly. Other instances of BubbleUPnP show the non-OH CXN renderer, but usually not the OH CXN.

In UPPlay the control point sometimes loses track of where the renderer is in the track or queue, but I am guessing that is an issue with UPPlay.

There is one slight complication which might be relevant. The CXNv2 ships with an on-board "Chromecast Built-In", which shows up on the server as a regular Chromecast. But it has the same IP address and friendly name as the CXN, which cannot be changed AFAIK.

How to make the CXNv2 OH renderer show up in BubbleUPnP every time I open the app?

Cheers,

Marmite.

I'm a bit confused (a regular state of affairs).

You say "I am now trialling a new renderer - Cambridge Audio CXNv2, which does not support OpenHome"  

but later say "How to make the CXNv2 OH renderer show up in BubbleUPnP every time I open the app?"

If the CXNv2 doesn't support OH, you presumably won't be able to do so.

Don't worry, I'm often confused too.

The point of using the BubbleUPnP Server (well, one of the points) is that it emulates OpenHome for a non-OpenHome renderer. Then you can create and edit the queue from any OH control point, and the server maintains the queue as if the renderer was OH compliant.

Problem with UPPlay solved by updating to latest version.

Ah, I get it now. Thanks.

Still having trouble with disappearing OH renderer. For reference, the renderer and the server are both connected to the network by ethernet. The android BubbleUPnP devices are connected by Wi-Fi.

I have updated the BubbleUPnPServerLauncher.jar file as per the changelog, and the server is behaving better, media servers are appearing where there weren't any, and the OH renderers are appearing in all instances of Android BubbleUPnP. However, I think this renderer is misbehaving when it comes to UPnP interactions. I don't think it is really meant for the UPnP world. Is there some way I can test this and refer it to the manufacturer? (Cambridge Audio)

Forget this request. I have decided not to continue with my assessment of this device as a UPnP renderer. It does not support OpenHome and does not work well with BubbleUPnP Server, and therefore it is of little interest to me. However I should say that the quality of the inbuilt DAC is extremely good.

It's real a shame it's not OH compliant, and can't otherwise be made to play well with BUPnP.   

I use a Cambridge Audio CXA60 amp, and stream to it from Logitech Media Server, via a Logitech Duet* connected to its internal DAC.  The CXA60 has the same Wolfson WM8740 DAC as the CXNv2 — albeit only one of them, to the CXNv2's two — and sounds excellent.

* a RasPi-based set-up works just as well, given that Logitech haven't made hardware players for nearly a decade.

Best way to troubleshoot this renderer would have been to use Android BubbleUPnP to control it via pure UPnP (no OpenHome) to

check for any problem and record a log file. But I suppose it is too late now.

The search is now on for a DAC to match the CXNv2. The strange thing is that I am comparing it to my existing DAC - a Cambridge Audio DacMagic from several years ago, which also claims to sport dual Wolfson WM8740s. Plus a lot of other signal processing and filters which probably degrade the end quality. Because of this I am reluctant to base a decision just on what chip(s) are in use. And they vary hugely in price!

Dead right, yes.

That's the thing many people overlook about DACs — the actual chip is only part of the equation.  The implementation — the digital input and analog output stages, and the power supply — has a huge influence on the sound quality. As a result, the same chip can sound fantastic or terrible.

Hope you find the DAC your ears are looking for :-)

Update: I have received some help from bubblesoft in analysing the UPnP performance of the Cambridge Audio CXNv2, for which I am very grateful, and I have continued with attempts to use it with BubbleUPnP Server. As a result I will install this device and continue to investigate ways to improve UPnP performance. I am still experiencing some intermittent minor glitches, but I will attempt to find ways round these in the future. Looking forward to update 41 of the Server, which might help in this endeavour. Having OpenHome functionality makes a big difference and I am very grateful to bubblesoft for making it possible.
