I tried connecting the Apple TV back to my old monitor and volume control came back.. Does anyone why this is happening and is there any way to fix it?
Are you controlling the volume via IR? If so, just "learn" the new device. Settings > Remote and Devices > Volume Control > Learn New Device...
If the volume is set to Auto and it's doing it via HDMI, I am not sure. Did you try restarting your Apple TV while connected to your new monitor? Or, maybe turning Volume Control Off and then back to Auto?
It's on Auto and my monitor doesn't have its own remote control. I've also tried restarting and reconnecting everything.
I can actually set the volume but only through "Settings > Audio and Video > Volume"

The sad truth about HDMI-CEC is that although its a standard it is far from it. Some devices work and some don't. You can train the Apple TV remote to do IR volume if you have the TV's remote, but it sounds like you don't? I think I saw in one of the beta TVOS threads that apple is working on better support so it may get resolved with an update.
