I forgot to write that the streamer is a Volumio primo and it is connected with a coaxial spdif to the dac.
The nuc and streamer is connected with Ethernet cable.
Roon is playing but it cant find the spdif output so there is no sound. As soon as I connect the dac with usb cable Roon finds it.
We are able to play to our in-house Volume Primo’s SPDIF output using firmware 2.649 and Roon Build 521.
Could you clarify what you mean when you say that Roon is not able to “find” the Primo? Does the Primo appear in the Settings > Audio screen in Roon when the SPDIF output is selected?
I recommend rebooting everything in your setup, including the Roon Core, Primo, and your router. If this does not resolve the issue, I would reach out to the Volumio support team for further assistance as they would be in the best position to troubleshoot this issue for you.
The primos ouputs show up in Roon but there is no sound from any of them. As soon as I connect an usb cable between primo and dac a new output shows up in Roon and when I select it the sound comes on.
It seems that there is no handshake between primo and dac with spdif.
When using SPDiF, Roon talks to the Volumino software and not the DAC. Once you have checked that everything is set correctly in Roon then the next step is to check settings in Volumino. It is possible this is turned down in its settings for some reason.
Yesterday I gave it another go with trying to get roon to find the spdif signal. There was four outputs in Roon named USB 1 to 4. Last time I tried there was no sound from none of them. As soon as I connected an usb cable between the Volumio primo and the dac a new output showed up. When I enabled it there was sound.
Yesterday I unplugged the usb cable and started over. When I enabled output #2 the signal suddenly locked and there was sound.
I really dont know why it suddenly worked but now I am listening with spdif output and it sounds really good.
The only trouble I have found is that I cant play Aiff files in 24/192 with spdif. It plays but there is no sound. I have to manually change max output to 96khz, then there is sound.
Thanks for all help.
Glad to hear you were able to get the SPDIF output working on Volumio!
Are you having the same issues with 192 FLAC files? You can download a few sample media content from 2L Test Bench if you need to test.
If 96khz works as expected, there’s no reason why 192 should have any issues, provided your DAC supports 192 via the SPDIF input. I would reach out to Volumio or Mhdt support regarding this.
Just for future reference as well, when making any changes to the Volumio configuration via the WebUI, it is suggested that you refresh the webpage as the Volumio WebUI settings might not automatically update after applying them.
The Volumio Primo is currently in the Roon Ready certification process. I’m not privy to the current public capabilities of the device, insofar as it’s ability to act as a RAAT endpoint… it could be in the uncertified Roon Ready state or it could use Roon Bridge as a plugin.
