4.10 freezing when I click play or compile
Running 4.10 on OS X El Capitan.
I have a C++ project I made in 4.9.2 that is linked up with git. It was working fine the couple times I messed with it before 4.10 came out. Me, enjoying being on the bleeding edge of things, installed it right away side by side with 4.9.2, upgraded the project, and pushed the changes to the repo. I've been adding a few classes (one inheriting from actor, one from character, and one is an interface class) and working on a few levels until recently its started freezing for no explicable reason when hitting any form of play or when I try to compile, either from Xcode or from the editor.
The program becomes completely unresponsive, and I have to go to Activity Monitor to force quit the instance. I have tried 1) creating new projects, C++ and blueprint based. All new projects have this same problem. 2) Removing 4.9.2 and 4.10.0 and reinstalling 4.10.0 and it still does not work. There seems to be no rhyme or reason to this issue.
I had this same problem yesterday, and then around 2 hours later it was fine again. Compiled several times without issue. Now today it is back. I'm unsure what to do or what is causing this.

I figured out my issue. A while ago I broke my sound card by plugging in an audio interface via the 3.5mm output jack on my computer and then powering the interface with a super sketchy USB wall wart PSU. My computer, unless plugged into my HDMI monitor or into my audio interface via USB does not have any sound devices. Any action I perform in Unreal that causes it to output sound without an audio device causes it to freeze.
I just tested this with my USB headphones. I tried to play in 4.9.2 and 4.10.1 without any audio devices plugged in and it froze. Once I connected the USB headphones it resumed and ran fine. I then tried compile in both without it plugged in and it froze. I plugged it back in and it resumed. Not sure why this is an issue on OS X but not on Windows (Bootcamp), as I have ran and compiled many times without any audio devices.
