Connection with external Audio Devices UPnP / DLNA

I run Audirvana version 3.5.42. on a MacBook Pro under MacOS Big Sur. The Audirvana® (latest version from Apple App Store) runs on an iPhone iOS 14.2.
I’m using the Remote for sending my high resolution files, stored on the MacBook Pro inside my Home Network to at least 3 different DLNA/UPnP devices on different floors in the house. The sound is beautiful and I really enjoy listening.
In my opinion there are two major issues with the remote which makes the usage very inconvenient in my system-environment
Firstly, for every start on the iPhone the Remote needs to newly connect to the Audirvana running on the MacBook first, which takes 1-2 seconds, before you can use the remote. Some times it takes a bit longer. Is it a bug or a feature? :wink:
Secondly, the more bigger issue in my opinion is definitely a bug.
If you’re playing an album and you want to jump to the beginning of the next song - that’s what I would like to do very often - it jumps to the 2nd. next song. And since then, the system gets totally confused until you stop playing using the STOP button. So it’s impossible to jump back and forth for playing individual songs of an once loaded album. You need to reload the album again and start playing with the next title.This is totally annoying for me.

I hope this major inconvenience can be corrected soon.

Cheers Michael

Hello @Massai,

Can you send me a copy of the “Debug Info” while you get this issue? You can get it in Audirvana Settings>General>Debug Info

Note: By clicking on the Debug Info button, Audirvana automatically copies all its content, all you have to do is paste it in response to this message

Hi Damien3,

Thanks a lot for picking up the topic immediately. :wink:
Three takes of debug info have been sent in a MS Word doc. via e-mail in order to focus here on the conversation only.

What did I do for taking the 3 takes of the debug info:
I started Audirvana on my Mac. Then I started Audirvana Remote (AR). I started to play an album via AR. Then I took the first debug info.
Then I pushed the >> button on the AR and it jumped as expected to the 2nd next song. Here I took the 2nd debug info.
Then I let play for a while until the end of the end of 2nd next song. After that Audirvana started playing the before skipped song!
During playing the before skipped song I pressed >> on the AR again and it jumped again to the song after the next song. At this point I took the 3rd. Debug info.

Best Michael

Hello @Massai, sorry for the late response. The issue you have is due to this :point_up:. It means there is no gapless playback when you use your DAC in this mode, you then need to ask PS Audio if they have a firmware update for your DAC to enable this functionality.

7

Hi Damie3,
Thanks for your response. I assume your statement is based on the entires in the debug info file I was sending.
DLNA 1.5: Yes
Gapless playback: No
Missing events workaround: No
Can play native DSD: No
Number of channels: 2
Use as stereo device only: No

For 2 of these entries I definitely know they are wrong at least for the PSA DACs:
Can play native DSD: No
Use as stereo device only: No
So maybe the Gapless playback entry is wrong too?

Honestly, I don’t believe the mentioned reason for the misbehavior of the Audirvana Remote (AR) is correct. Can you please explain technically how the “gapless playback” function influences the “Play next title” function of the player. I’m interested to understand and learn how this is technically related.

Best Michael

Audirvana Remote do not have an impact here, it’s the device you try to play with Audirvana that have the issue. If you try with your TV selected in Audirvana for example, it will have different capabilities than your DAC.

Based on the description you made here:

I started Audirvana on my Mac. Then I started Audirvana Remote (AR). I started to play an album via AR. Then I took the first debug info.
Then I pushed the >> button on the AR and it jumped as expected to the 2nd next song. Here I took the 2nd debug info.
Then I let play for a while until the end of the end of 2nd next song. After that Audirvana started playing the before skipped song!
During playing the before skipped song I pressed >> on the AR again and it jumped again to the song after the next song. At this point I took the 3rd. Debug info.

It’s a symptom of not having gapless playback implemented over UPnP in a device. This is why we asked you for your debuginfo.

The information are given by the selected DAC, they are not changed by Audirvana, this is how we can determine that there is no Gapless playback for your DAC in UPnP.

Gapless playback may have been only implemented for wire (not ethernet) connectivity, it can also be a choice made by the manufacture, a bug or a feature that is available with a more recent firmware.

Does Audirvana behave properly if you jump tracks using the Mac ui?

10

No, it behaves similarly via the Mac ui.

11

Thanks a lot for the information Damien3.

Nevertheless, An interesting fact is that the PSA Dacs have no problem with jumping back and forth if I use JRiver Audio Player including its remote. Would it perhaps be possible that the Player itselves could take over responsibility for managing gapless playback properly?

12

Hi @Antoine.
Hope you will find the time to answer my latest question.
Thanks in advance.
Best Michael

13

JRiver is a UPnP server and Audirvana is a UPnP media renderer which are really different in UPnP. In the case of Audirvana we rely on the capabilities of the DAC if a capability is not embed in the DAC then we can’t use it. In the case of JRiver, as it’s a UPnP server, the manufacturer may have forgot to add the gapless functionality for media renderer software. The best way to find this out is to contact the manufacturer of your DAC as said previously.

14

… Although I did not get an precise answer to my precise question …
I understood that Audirvana is a renderer and expects gapless playback to be managed precisely by the DAC it is playing to if requested by the renderer.
Also I understood that Audirvana for the same reason will not implement gapless playback into their renderer, even if that would be possible.
That in my opinion would rise to question the functional product philosophy of Audirvana.

Anyway, I already picked it up with PS-Audio and await an answer shortly.

Best Michael

Surprised to see you call Audirvana a DLNA renderer.

It is not a renderer. Renderer is a device where the media is pushed to for playback by a controller. For example a networked dlna player device.

IMHO Audirvana is acting as a control point when it plays to a renderer. Audirvana is also a media server as it exposes an http server to the renderer

16

But it’s not a UPnP/DLNA server as the end device that is DLNA compliant can’t browse the Audirvana library, nor can a control point software. Also Audirvana can’t browse third party UPnP/DLNA servers, like a control point software should.

Technically it’s a dedicated control point software that can play to UPnP devices from local library.

17

Yes you’re right. I should have said Audirvana implements parts of control point (DMC) and parts of a media server (DMS) sufficient to push media to a media renderer (DMR) from its own library.

My point was that it doesn’t seem like Audirvana itself is a media renderer in the DLNA realm.

18

It sounds like a layman explanation.

Whatever dude. ¯_(ツ)_/¯
It makes sense if you understand basic DLNA terminology.

Hi @Antoine,
PS-Audio said:
Gapless playback is a function of the music software. The DAC itself simply processes the signal and converts it to Analog. So DACs really don’t have issues with gapless playback, this would in fact be the responsibility of the music management software.
Thanks to VoyagerDude and bitracer too for their clarification on “what is a renderer ?”!
I now understand that Audirvana needs additional music software like a network player usually provides (e.g. from Denon or Auralic). That means in my puristic system I can play to the DACs via the network using Audirvana but I can’t totally control the playlists because of gapless playback is missing in the DAC.
I think if gapless playback would have been implemented in Audirvana directly in order to control the playlists locally on the PC Audirvana is running on it would be an advantage for all the puristic systems of audiophile people like me who don’t have music software on their DAC.
I’d like to rise the question now whether it would make sense to implement gapless playback in Audirvana directly in order to expand a good product for new more puristic customers.
What do you think?
Best Michael
