We have then to devise a way to discard the first enumerated device without
breaking everything.

Could you try to add the statement

      allegro_message("lpGuid = %p", lpGuid);

line 200 of src/win/wdsound.c ? Then recompile, reinstall and try for
example the dxwindow.exe test in tests/win. What values for lpGuid are
displayed ?

Or some compatibility problem in DirectSound. Here's what the DirectX 7 SDK
says about lpGuid obtained through enumeration:
"lpGuid
Address of the GUID that identifies the DirectSound driver being enumerated.
This value can be passed to the DirectSoundCreate function to create a
DirectSound object for that driver"

There seems to be no condition on the use of lpGuid once it is obtained.
