I thinks it's not so hard to add 3D sound feature using
RoarSound

Engine info:

Open Source Direct Sound Engine without DLL.
Support WAV and OGG,WMA,MP3,MIDI formats. Extremely Easy to use.
Very good alternative to commercial sound engines.

Another free sound lib is Zeal Audio

Thanks for those links, they look interesting! Hopefully they do not add too much in size to exe-files.

ZGE is getting close to becoming open source. Then it will be easy for other developers to try integrating other libraries too.

Thats great news. I will wait for ZGE Source Code.
Maybe I will make own version for 2D games based on ZGE Source.
