Computer updated and now Roon is blocked

You may want to try the dealer that you bought it from.  I had a similar issue and had to go into my settings on my iPhone (in your case computer) and reset a several of them.  Where are you located?

Update your graphics driver from HP or better yet the graphics vendor. I think Roon is graphics oriented.

While you're at it do the same with the HP audio driver(s).

1.Can you be more specific about what occurs when you launch Roon?  Is there an error?  What**does** happen and exactly when does it stop?

2. Just for fun i booted full roon (not running as a core tho) on my Lenovo Windows 10 machine with latest updates.  Worked fine.  I normally run ROCK and have my clients on phones and Macs.

Roon is very low stress re: graphics. I run it on all sorta of crappy systems.

Theer ar eno audio drivers per se.  Its digital out on USB or ethernet. There are USB audio profiles, but those are now part of Win10

jeffex00,

You may have some corrupt operating system files.  Open command prompt (as an admin) and run the command sfc /scannow.  From the task bar > type here to search > enter cmd > open command prompt as admin.  If the results show integrity violations, run it again.  You may have to run it several times.  More about this feature are here.

I would not update any of your drivers until you have verified that you have the latest version of Windows 10, Version 21H2.  Sometimes manufacturers will have different drivers depending on the build version of Windows.  Here is the Windows 10 Lifecycle Policy.

From the task bar > type here to search > enter winver > a window will open and show the version.  If it's not 21H2, then update your OS using the Microsoft Update Assistant found here.

Click the "Update now" button and follow the prompts (be sure your laptop is plugged in and charging).

Once you have 21H2, then use the HP Support Assistant to check for driver updates.  The latest version is Assistant 9 and can be downloaded here.

If these steps still don’t resolve the issue, then doing a complete uninstall/reinstall of Roon would be a good idea.  I prefer using Revo uninstaller (free version) opposed to the built in uninstall options of Windows.  If you decide to use it, be sure to scan for and delete the leftovers.  Revo can be downloaded from here.

If you followed all these steps and the issue is still unresolved, following the Roon recommend fixes posted by noromance would be a good idea.

Hope this helps.
