Hello!

Nearly a year ago I made this bug report, and as of the latest patch; it's still an issue.

The Apple Cinema Display (in my case), along with other USB audio devices (according to cursory internet searches) causes the game to fail to launch. Disabling the built-in speaker fixes the issue. The issue persists with both DX9 and DX11 clients. It persists 100% of the time, regardless of account, server, etc. The game crashes immediately upon pressing 'play'.
