Music doesn't play and progress bar bounces back and forth

I’ve been using Roon for several months with no problem. I recently moved to another address and approximately 2 months lapsed since I set up my system in my new house. Everything was set up exactly as before. However, when I attempted to use Roon, I cannot hear the music and the progress bar bounces back and forth. Everything else appears normal but it cannot play music.

When I go to ‘Settings’ >‘About’, the Core attempts a download but fails and returns “There was an error checking for an update”.
The remote app says: Roon version 1.8 (build 952) stable
The Core says: Roon version 1.8 (build 931) stable
I suspect the discrepancy in the versions is the issue but I don’t know how to resolve it.

In order for Roon’s support team to better assist you, can you please provide a brief description of your current setup using this link as a guide.

Make sure to describe your network configuration/topology, including any networking hardware currently in use, so they have a clear understanding of how your devices are connected. Thanks.

What PC is running your core?

The Roon core runs on an Intel NUC 10 with i5 processor which is connected to my router in the office. My system/streamer is located in another room and is connected via an ethernet cable to a TP-Link AV2000 Powerline adapter plugged into a wall outlet. I can connect to Qobuz and play music over the internet with no problem this way, and Roon connects with no problem and appears as it always has. In my previous house the streamer was connected directly to the NUC 10 via ethernet cable. I didn’t use the powerline adapter in that situation.

And the OS,. Windows, ROCK, Linux?

Linux on the NUC 10.

If you using RoonServer on a basic Linux like Ubuntu then you can just download the latest Linux install package from Roons download page and installi it. That way core and client will be in the same version.

I may have mis-spoken. When I did the installation, I followed the instructions from your “Knowledge Base” for “Roon Optimized Core Kit” which I believe uses Linux. So, the OS would be ROCK. Sorry for not knowing the correct nomenclature if it makes a difference.

It appears to me that this is the problem. There is no indication of what is causing an error. After reading everything that I did for the initial installation, it seems like a lot of work to reinstall ROCK. I would think there should be a simpler way to do an automatic update of ROCK since it is built into the software.

Hi Jim,

Just a fellow user like yourself. Yes, ROCK is RoonOS which is different than the popular Linux versions, which is why I mentioned Ubuntu. And, Yes, it does make a difference as my response now is different.

Go to the ROCK Web UI page, and then manually run a re-install on the OS. This will grab the latest version. Here is some docs on getting to that page:

Other ways of accessing the Web Interface:

The Web Interface can also be accessed by:

  1. Typing in the IP Address of the RoonOS Device in a Web Browser

  2. Typing the hostname, for example http://rock , http://nucleus , or http://nucleusplus

  3. Typing the .local suffix for the device, for example http://rock.local , http://nucleus.local , or http://nucleusplus.local

Well, I just read your reply, but I had already attempted a new install (not a re-install) which of course wiped the disc on the NUC. I followed directions using the ROCK install guide. I extracted the codec file ffmpeg.
Instructions say:
2. Connect To Roon OS - Roon OS exposes a shared network folder called Data. You can access this SMB share by following the instructions here.
When I follow the link “here”, it says to open explorer and enter \ROCK\ or substitute ROCK with the ip address which is But the result is “file not found”.
So, right now my problem is adding the codec file but I can’t access the Roon OS.

That would be File Explorer on a Windows PC. And I enter \\rock and I get this

Under which you will find the Codecs directory. You just past the ffmpeg file there.

That was what I needed! Everything is back up and running as it should. I installed my last backup from April and I’m back where I left off. Thanks for your help!

On a side note, I don’t understand why the Roon Remote and Core builds could be so much out of sync.
