· I have a Roon Nucleus One attached to a Marantz AV10. The Roon Ready Av10 plays through ethernet. I have heard that there are some limitations to playing through ethernet. If I wanted to have it play through the HDMI cable attached from the Nucleus One to the AV10, how do I activate it?

· Router is an Asus RT-AX86U. I have several switches for all the ethernet devices. I do use a VPN except when it interferes with Roon.
Simply connect an HDMI cable between the Nucleus One and a HDMI port on the Marantz. Go to Roon’s > Audio screen and enable the relevant port in the Roon Server section. On the Marantz switch the input source to the HDMI port that the cable is connected to.
Open up the Roon Device Setup screen on the relevant port; for example:
In the Roon Device Setup screen, you want to scroll down and open the Advanced Settings section (note: no scrollbars are shown, but it is a scrollable window). Then scroll down further to show the Channel layout setting and set this for multichannel working. For my Denon AVR this is 7.1:
@Geoff_Coupe for context, we have been through this in another thread, but as far as I can tell @Gary_Cardinale‘s Settings > Audio doesn’t show any HDMI device, so he can’t enable it:
I found another old thread that looked similar and support had this other user delete a cache folder on the Nucleus (or something similar), but I didn’t want to mess with this and so I suggested that @Gary_Cardinale opens a Support case, which is now this one.
OK, thanks for this - indeed no HDMI outputs are showing for the Nucleus One of @Gary_Cardinale, so lets wait for @support to pick this up after their weekend break…
Thanks for sharing your report, we’re unable to see the Nucleus tied to your account, so we’ll need to request a set of manual Roon Server logs from you to review what might be going on behind the scenes.
Can you please use the directions found here and send over a set of Nucleus Roon Server logs to our File Uploader? Once logs have been uploaded, please let us know so that we can check the server for your files, thanks!
Thanks for sending over a small subset of your Nucleus logs. We can see that the Nucleus One’s own HDMI audio port (hw:CARD=PCH,DEV=3), operating as a local ALSA output. It is connected and available.
We’re only seeing the AV10 connected via ethernet though, not over HDMI.
Could you share a screenshot of your Audio Settings page?
I assume you have already tried:
In Roon → Settings → Audio, enable and select the "Nucleus One HDMI Output" zone
On the Marantz AV10, manually switch the input to the HDMI port the Nucleus cable is connected to
Um, I suspect that the Nucleus One ALSA entry is in fact your HDMI output. Why don’t you try scrolling down to reveal your Advanced settings as I suggested earlier?
Look, as I said a week ago, you need to scroll down on the Nucleus One HDMI Output screen to reveal the Advanced settings - and there are no scrollbars on the screen to indicate that it is a scrollable window…
Here is what I have done. I have my Roon Nucleus One device attached to the Marantz AV10 via HDMI. When I play roon I have 2 choices, 1) use the AV10 as the device or 2) use the Nucleus One. Here are the results:
AV10 as the source… the music plays fine through what Marantz calls HEOS. The music is always 2 channel even if I play one of my 5 channel SACDs. It can play through all my speakers but it is always 2 channel. I get a nice display of album art on my Sony TV however. And since I am playing through the AV10 the music is not coming over the HDMI cable from my Roon Nucleus. I can uplug the cable and it makes no difference. It is communicating with roon via ethernet I presume.
Nucleus One as the source…the music will play an actual 5 channel SACD that I have put into the roon library as 5 channel SACD. This was setup in roon. The music definitely plays from the HDMI cable. When I unplug the HDMI, the music stops playing on my system. The downside with using the Nucleus One as the source is that I don’t get any nice album art displayed on my Sony TV. All I get is some ugly white lettering that tells me what version of roon software I have. Is there any way to configure roon so that I actually get album art showing up when I choose the Roon Nucleus as my source?
The “source” of your audio is always the Roon Server in your Nucleus One. You have two audio devices available to choose from, both of which are connected to the AV10 but by different routes: HDMI and ethernet/RAAT (Roon Ready). Think of the Audio Devices as being equivalent to Zones - you have here two distinct Zones with different characteristics (one supports Multichannel, the other supports only stereo).
BTW, you can edit the name of an Audio Device to name the Zone into something more meaningful - e.g. change “Nucleus One HDMI Output” into “AV10 - Multichannel”.
The HDMI port on a Nucleus is used to send audio only, it does not display album art. Since the Nucleus is designed as a “headless” device (i.e. no monitor or TV is needed to be attached for its operation), only diagnostic information will be displayed if a monitor or TV is attached - and that is what you are seeing when you have the Sony TV turned on and connected to the the HDMI output of the AV10. This is stated in the Nucleus manual, but it’s in condensed form, so you may have missed its significance.
If you want to see album art and “now playing” information on your Sony TV, you probably have two options.
Most modern “Smart” TVs have a web browser built-in - you can use that to display the information. Go to Roon’s > Displays screen to do that (you’ll find a link to a Help article on that screen).
A Chromecast Ultra can be used, connected to your TV, to display “now playing” information from any Zone.
I use option 2 in my setup with my Denon AVR and Samsung TV…
This was VERY helpful! Thanks. I have used option one and connected to the TV, and it works fine. The problem is it makes things a little messy when I want to use the TV with another input. For some reason the sound does not work and I had to fiddle a bit to get the sound back on. Other than that this all is alot clearer. Thanks again.
> Audio screen and enable the relevant port in the Roon Server section. On the Marantz switch the input source to the HDMI port that the cable is connected to.
