I have a separate PC set up as Core and I use Roon remote on my office PC with my office audio set up. The office PC is running Windows 10 and I use the latest version of Chrome for my browser.
Streaming videos on FB and YouTube work fine prior to using Roon, but after stopping Roon playback or exiting Roon completely, unless I reboot my PC, no videos from any website will stream. I can even have started to stream a video, pause it, start Roon and exit and then try to start the video again and it won’t stream. Play buttons work fine, but no steaming video.
My PC is an i7-3770K CPU w/ 32 GB of RAM running Windows 10 64 bit.
