My headless (and sound card-less) Almalinux 8.9 virtual private server is now accessible via an xrdp connection. My XFCE desktop is visible without any issues. [Since my host uses Nodeworx, I had no choice but to run xfce.] The sound on YouTube videos playing in Firefox on the headless system is really difficult for me to hear, and I'm just starting out with Linux. The PulseAudio Volume Control, which is installed on the VPS, indicates that Firefox is producing audio. The "Dummy" output device is being used. Even with my Windows Remote Desktop connection, which is set up correctly to play sound on my end, I am still unable to hear anything through my headphones. I don't think the PulseAudio plugin on GitHub is compatible with AlmaLinux; it only works with Ubuntu. https://dinosaur-game.io
