Audirvana via Trinnov Amethyst as a renderer

Hello all,
i am experiencing some issue using Audirvana with my Trinnov Amethyst. So i hope you can help me with that.
I use my imac 27 with Audirvana latest version as a renderer (from my Nas or streaming) connected by ethernet on my local network and to the Amethyst. So in detail, whatever the length of the songs I play, the music stops just before the end of the second piece I read. Sometimes in the middle of the night the buffer seems to release its flow and I find myself with music.
The problem occurs regardless of the number of devices connected to my network (with bubble upnp/minimserver on the nas connected or not) and the music stops always few seconds before the end of the 2nd song, even though and the timer of the song don’t always start.
For info, i have tried other softwares and they worked without this problem (and also asked Trinnov), but i am here because i obviously would like to use Audirvana.

Does any of you ever had this kind of trouble?

Best Regards to all for this difficult time

Jonathan
I can provide the debug infos

Do you use upsampling? If yes, try without that.

Hi bitracer,
thanks for your suggestion, yes i generally use upsampling, but even when i disable it, it does not change the outcome.
Still blocking just before (2sec) the end of the 2nd piece, and i have just noticed that the name of the 1st song is still displayed (on desktop, in the player bar next to the control)…
cheers

You said with or without upsampling enabled you experienced this issue?

Can you also decrease your buffer audio memory to 3000MB or 2000MB?

thanks for looking at it. Yes i can confirm : the outcome is the same whatever the upsampling options are, and to be sure i have just made 2 another tries just now with your recommendation regarding the buffer, and i have the same issue, with the same symptoms.

Just to be more specific on the context maybe to orientate the search, before asking, I have tried to eliminate all other possible troublemakers in the music chain, i have also changed and tested all the RJ45 cables, tried to have the renderer in direct without router etc… in the past i used the usb output on an Ayre device with no issues at all. So this seems too be very specific to the communication with network connection…

You said previously that you contacted Trinnov, what did they said about the issue you are facing?

It was last year or something like that, they said, they couldn’t see how the symptoms could come from the Amethyst. They advised to run some tests with other softwares and then, if it wasn’t working they would investigate further.
But i did not contact them again, as i have found the following : i tried Jriver and Roon, both worked normally, (even though i had some little glitches with Jriver after long listening sessions but was globally ok).
Then i started to use bubleupnp et minim server directly from my nas, so i came to the conclusion that the trinnov was working normally and i had a decent option to listen to streaming and all as this wasn’t my priority.
Now i am considering a tweaked macmini as player and as i like the overall app and Audirvana interface, i would like to be able to make real tests and to enjoy all of it.

Hello @Jonathan_Copiatti, can you run a test of the gapless of your DAC to see if you the issue? If it’s the case that would mean there is an issue with the gapless feature of your DAC. This problem may not appear with Roon since they a proprietary protocol which is not UPnP.

Hello Damien,
thanks, so to be more specific, the system is as follow, mac/audirvana+ RJ45 to Trinnov Amethyst + (Aes to) an external dac + amps etc.
So the dac is appart from the equation as the communication is via AES and works perfectly from the amethyst to the dac with all sources.
The issue is just in the communication between the mac/audirvana and the Amethyst in RJ45 network, and talking about upnp, i had no issue with Jriver from the mac or bubble upnp directly from the nas, which both uses upnp to communicate to the Amethyst… so i don’t think there is an issue with the gapless there, but why not testing, how could i do that? i can not find anything on the manual : hhttps://www.trinnov.com/PDF/Amethyst_English_Manual_V3.8.pdf
From other user experiences there is no flaws in the protocol in general, and to be on the safe side that’s why i’m also not using wifi for instance. But i will ask now on another forum with trinnov users.
Please let me know if it still makes sense to run a gapless test.
Best Jon

You can try gapless by using bubble upnp and using a live album and if you have pause during transition that mean your DAC have a gapless issue.

Hi Damien,
thanks for your answer, it’s tested, no gapless issue at all, going from one live piece to the next totally smoothly.
I have contacted Trinnov this afternoon as well, and they ran a first test on my machine which was totally normal, they will have a look as well later on to see if they have the same issue on their own.
Best
Jon

Hi @Damien3 for info,
the test made by Trinnov on another Amethyst revealed the exact same symptoms, (display blocked on the first piece infos (precisely just 2 sec before the end of the countdown) and the music stops at the end of the 2nd piece)
They will investigate as well, any lead on your side?
many thanks
Jon

Hi,
so i assume there is no new leads ?
cheers
Jon
