OpenAL 1.0 vs 1.1

[PawelO]

Hello,

I need replacement for DXSound which I was using in Delphi, and I'm trying with OpenAL and examples from www.noeska.com/doal . It works fine, but only with OpenAL32.dll 0.9.5.1. When I replace library with OpenAL32.dll 6.14.357.24 or similar, there is no sound, and no error messages (also in alGetError) - just nothing happens. I tried with OpenAL header from noeska.com, which is supposed to support OpenAL 1.1 (so dll 6.14.357.**), as well as Free Pascal header - with the same effect. Checked on Windows XP and 7, I'm using Lazarus 1.2.6.

What can be the cause of problem? Is there a possibility to make it work with OpenAL 1.1 to avoid confusion with dll versions?
