I like to use my TV as a second monitor, but without the ability to change the audio device that ESO uses, I'm stuck with both gameplay and what should be TV audio both coming out my computer. I know I could download some applications for Windows that allow for manual switching of which programs use which audio devices, but I'd really not like to, especially since this is the only game I think I've ever seen without this option built in.
I mean, it's certainly possible this is already in there and I just overlooked it, and if so I'd love to know where it's hiding out.
