--- Comment #16 from Roberto blackfire@blackfiregames.com 2010-04-08 11:15:48 --- I'm using OpenAL ver. 6.14.357.24. in software mode. Some cards have problems with the full HW mode enabled, so I just told OpenAL to run it in soft mode. OpenAL was integrated to Ogre3D using OggOgreSound: http://www.ogre3d.org/addonforums/viewforum.php?f=19
The game has been tested on wide range of HW and the sound worked fine on WinXP, Vista and Win7.
Let me know what other info would help. I can give you the lines of code where I init the sound, and the rest is done internally by the OggOgreSound add-on.
