Prerequisites: Using latest Sandboxie x64 on Win7. The problematic Sandbox uses the standard settings without any special restrictions.
As many others I do not fancy to run steam outside of a sandbox. Usually that never gave me too much trouble with the few games I play, after some tweaking every once in a while.
The new game Orcs Must Die! installs and runs fine in my "Gamebox", but it has no sound. I tried many of the various possible fixes by lifting Sandboxie restrictions bit by bit, but I cannot get the sound to work. Strangely enough the game even shows up in the Win7 sound mixer when run. The sound problems connected to a sandboxed use of the game seem to be known, although not really intensively and with no fix offered.
Directly installed onto a virtual machine the sound works fine.
A demo of the game is available on steam.
Any pointer into a direction on how to further explore this problem or how to fix it would be highly appreciated.

Qhorin
P.S.: Congrats tzuk on the most recent "round" final version and hopefully many more to come

I celebrated the occasion by upgrading my 1-year license to a lifetime license, thanks for the great offer!
