With VLC I can control the volume with the scroll wheel and go to 200%. Thing is, we’re watching on the couch, not near the PC. With Jellyfin I’m constantly fiddling with the KB or hunting with the mouse to raise and lower volume. Any way to both bind the scroll wheel to volume and push it past 100%?

Kodi with jellycon is really good!
That’s good to know. I’ll be setting it up to give it a whirl soon then.
kodi + jellyfin (or emby) is absolutely amazing!
