either something is missing in Windows for the DX9 emulation to work properly, or something may be going on with your drivers. The DX9 issue has a fairly easy fix: re-install DX9. Not your current DX11, but the legacy DX9 redistributable. It's a glitch that goes back to Vista where some DLL's are missing, and the off-line redistributable installer fixes it.

If that doesn't resolve the DX crash, post your system specs and perhaps someone else has the same sound and/or video cards and can suggest driver versions to try.
