Does Lumin U1 work with Logitech Mediaserver when using the upnp bridge?

[Schoeppi]

Hi,

 

I try to find out if the Lumin U1 transporter is able to work in usual DLNA / UPNP mode or is only useable with open home compatible apps like Linn Kazoo.

 

I'd like to use the U1 with my Logitech Mediaserver and the iPeng app. If the U1 can also work in normal UPNP / DLNA mode it should be possible to connect the device via the upnp bridge plugin.

 

Has anyone tried this before or does anyone have anU1 and can try to connect it to the Logitech Mediaserver for a quick test?

 

I know there is a deticated Lumin app and Linn Kazoo should be also useable, but because I am blind and I need an app which is useable with my screen reading software I do not have much possebilities. Linn Kazoo is accessible and the Lumin app seems also to be useable, but the best useability in my special situation is still iPeng with the good old Logitech Mediaserver :-(.

 

It would also be helpfull if anyone could say if the U1 can be used with MConnect or BubleUPnP or any other app, everything is interesting.

 

BTW.: Roon is not accessible at all, so please no hint for Roon :-(.

 

Cheers and thanks a lot for any hint,

Yes, the question is, is the Lumin firmware not only OpenHome compatible and will it work also with normal UPNP standard..., whatever this standard is. I've not yet found an answer to this queswtion...

Hi,

 

just for the records....

 

I was able to connect the Lumin U1 with the UPnP bridge plugin to my LMS.

 

Http mode has to be set to fixed and transcoding has to be set to PCM. Playing gapless and also listening to hires material is possible with this settings. Transfering meta data beteween LMS and the player and also the behaviour when a playback is paused is not so good currently, because a track starts from the beginning when paused in the middle.

 

But at least it works and music is not downsampled and that are the most important points for me....

 

Cheers,

Yes, I also was not happy to read that the implementation of the http stack of the Lumin devices seems to be not that good :-). But I also think that is related to the OpenHome extension and to the fact, that Lumin is interested in the best integration with their own app first.

 

In the end it matters how good the device is sounding and if it can  be used with an app that is also accessible to me and has all the features I need.

 

I had an Aries G2 from Auralic before and I was only able to use this device with Auralic Lightning app, Linn Kazoo or the Lumin app. All this apps are not very good to use for me in my special situations and all apps had areas that are not accessible and are very complicated to use. The Aries G2 is a good device and I liked it very much for its sound, but when I am not able to use it and using means stress for me this is no good solution.

 

I've tried many things to get the Aries G2 connected to the LMS, but in the end it only worked with the AirPlay bridge and that means that listening to hires material was not possible. So this was not what I wanted...

 

Now, with the Lunin U1, I have a also very good sounding device, I'd even say it sounds better then the Aries G2. I can also use Linn Kazoo or the Lumin app, but aditionaly I can also use LMS and iPeng, which is the most accessible solution still.

 

And over the wekend I've found out, that also Audirvana and its remote app for the smartphone is also very good to use and also very accessible and it is also working with the Lumin streamer.

 

So in the end every thing is fine for me, no matter if the implementation of the UPnP or http stack is bad or not. The most important thing it is working and even mor important...., it is sounding good!

Just trying to provide an explanation of what's happening, not denying we may have an issue regarding this part of HTTP functionality:  We require the use of HTTP Content-Length and range requests, which may not work well with chunked transfer encoding in some situations.

So maybe you can try to make the http stack more standard conform in future firmware releases, if possible. that will make the Lumin devices more compartible to the rest of DLNA / UPnP capable apps and programs.

 

Like said, its no problem for me currently. I am happy that the device works at  all and this is much more then with the Auralic device I had before. I can use more apps and the sound is equal or even better...., so every thing is fine. And ofcourse I hope this will be also the case for future firmwares....

 

BTW.: Is it possible to roll back a firmware on a U1 if a new release will not longer work? If turned on automated firmware updates, maybe I should disable it to be save that my current setup will work stable?

 

I'd like to have new firmwares ofcourse, but I also have to make sure that my system is accessible and works for me in my special situation as a blind user....

 

Cheers ans thanks,
