Describe the issue

Playing a playlist created in Roon with around 70 tracks from both Tidal and Qobuz, the songs from both services will be randomly stopped. While it stopped, from UI on my phone, it looks like my endpoint just disappeared for a second. It will comeback, but I have to press play button again to continue playing.

I ran roon server on a PC with i5-11400, 32G ram, lots of SSD and HDDs.
Everything is wired with Ethernet cable.
The endpoint is a ChromeCast Ultra

How FW/SW are up to date.

Describe your network setup

Router Xiaomi Router BE3600, wired connection to1Gbps to HPE 1810 24ports, Wired to Chromecast Ultra.

Hi @POCHUN_YEN,
Welcome to the Roon community. I’m sorry an issue is what brought you here for the first time. From what you describe a disconnection is happening between your server and the Chromecast endpoint. As a first troubleshooting step can you please restart the machine hosting your Roon server, your router and the Chromecast device?

Additionally can you test whether this is happening with local content as well. If only streaming content is affected then something else is likely going on.

Hi Daniel,

Thanks for the quick response.
I have done all the rebooting and checking before writing the first post.
I have also replaced all Ethernet cables in my house.
But the problems remain.

As for local content, I do not have sources for those files…
I just use roon with streaming services.
So I am not sure how to proceed with this one.
Do I have to buy cd and rip it or go buy music files online?

Is there any other way to check?…or maybe somewhere in the UI where I can see error messages when the problem is happening? ….it is difficult to deal with this without enough info

Brent…

Hello @POCHUN_YEN,

Thank you for the update.

We’ve gone ahead and enabled diagnostics on your account. Based on the logs, we’re seeing frequent disconnections of the Chromecast Ultra device—approximately every 5 minutes.

As a quick test, could you please run the following command from a computer on the same network and let it run for 10–20 minutes? This will help us verify the stability of the connection:

ping 192.168.31.123 -t

Let us know if you see any packet loss or timeouts. This will help us determine if the issue is network-related.

Looking forward to your results.

Hi Vadim,

I have tried the test u suggested
Results are
0 packet loss, out of 1869 packets…
Max ping time was 15ms, and average time is 0ms

I hope this helps…

Hello @POCHUN_YEN,

Thank you for the update.

Would you kindly try to wire Chromecast ultra and Roon server to the main router exluding “HPE 1810” the from the setup

Let’s try a fresh database and see if your issues persist:

  • Create a Backup of your current database
  • Exit out of Roon + RoonServer (from taskbar area)
  • Navigate to your Roon Database Location
  • Find the folder that says “Roon Server” and “Roon”
  • Rename the “RoonServer” folder to “RoonServer_old” and “Roon” to “Roon_old”
  • Reinstall the Roon App from our Downloads Page to generate a new Roon folder
  • Verify if the issue persists on a fresh database before restoring the backup

Here is the process outlined from a Windows machine:

All Roon_old on Windows

Hi

Just to clarify, before I start to mess around my cabling…haha
Do u mean I re wire Chromecast to my directly and also try a fresh database at the same time?

Or you mean do these 2 tests separately?

Thanks…

Just a quick update,
I have connected Chromecast directly to my router, the issue remain…
Will try to do the fresh database method later…

Thanks…

Hi @POCHUN_YEN ,

Thanks for the update, please let us know how the fresh database test goes!

Hi,
Just did the test, the problem remains….

Thanks
