--- Comment #11 from Adam Bolte abolte@systemsaviour.com --- It's not a duplicate actually. IMO, bug #26808 is about games expecting XAudio2_7.dll to be installed, when it's not getting installed automatically and causing certain applications to error out.
Wolfenstein: The New Blood had no issues installing XAudio2_7.dll. It didn't complain about a missing DLL during startup, and I even compared the md5sum that it did install to the same DLL from Windows 8.1 installation (which matched).
So this bug is about the DLL not working perfectly when it is provided - *not* about the DLL missing altogether. Isn't it supposed to work, or is that not supported?
