Hi all

This is my second bug report about Unigine Sanctuary. That old benchmark worked
fine (with Gallium Nine) in older Wine releases when the built-in
"openal32.dll" was present. 

However, since this file was removed somewhere in Wine 8.0 this benchmark no
longer works reliable. In my case I can confirm a reproducible hard hang of the
whole Linux environment.

Until now I was not able to find a native replacement of that "openal32.dll"
library which is on par with the former built-in one.

As a conclusion I would say that in regard to the stability and compatibility
of older Windows applications it was unwise to remove the built-in
"openal32.dll". The main argument was that no Windows version contains that
file so it is also not needed in Wine.

Well, it looks that the built-in "openal32.dll" variant is simply better than
the original native releases.

There should at least exist the possibility to download the built-in
"openal32.dll" file separately. This would allow end-users to made a manual
override by setting the former built-in variant as the native one. :-)

This was tested under Kubuntu 22.04 LTS with Mesa
24.0-git2401110600.813b19-oibaf-j (git-813b193 2024-01-11 jammy-oibaf-ppa). The
system is an old iMac 12,2 containing an Radeon HD 6770M GPU which is using the
r600 Mesa driver.

The Unigine Sanctuary benchmark can be downloaded from the original website:

Note, bug 56163 describes the problem of Unigine Sanctuary with the OGL/WineD3D
rendering path.
