@Antoine Yes, the core solution is free, as Veyon is open-source, but some advanced features or enterprise support may require additional costs. You can use the main functionalities without paying, but addons or custom integrations might come at a price. Regarding audio monitoring, Veyon does not support direct audio listening from remote PCs, including VoIP calls. It primarily focuses on screen monitoring, remote control, and classroom management. If you need to monitor audio, you may have to look for third-party solutions designed for that purpose. Hope this helps!

@AbrBahen I was in a similar situation with my website, and I managed to resolve it. The best approach is to check if there's a password recovery option on the login page—most platforms have a "Forgot Password" feature that allows you to reset credentials via email. If that doesn't work, try contacting customer support directly. Provide them with details about your organization, such as the email address associated with the account or any proof of ownership. In my case, I had to verify my identity and ownership through billing details or domain registration records. If your previous staff member used their personal email, you may need to request an update from support. I recommend reaching out as soon as possible to avoid any delays. Hope this helps!

Hello, (I'm just a user like you.) To do that with Veyon, you have to purchase the Internet Access Control plugin.

I have the same issue but my PCs have the latest veyon, 4.9.3, win 10 and file key authentification. Some PC have a duplicant screen from a working machine, some only gray all time. I tried clean reinstall windows, doest help, all settings same. Host names are unique and the veyon ports are open.

Hello, This would also be an interesting feature for me but as for now I have not found an option to diasble it. Anyone an idea?

Hello, on Linux the Screen Recorder add-on is provided in separate packages to avoid unneccessary FFMPEG dependencies when using one of the other add-ons only. You therefore need to install the appropriate package from https://github.com/veyon/addons/releases (Click on "Show all 26 assets" to see all files). Best regards Tobias
