5.1 surround sound in VLC with OSS4

I found switching to OSS4 works great with superb sound quality. But VLC 1.1.9 has only Mono and Stereo sound outputs, and no 5.1 surround sound output options when playing DVD wit 5.1 surround sound.

Is there anything extra I have to do to get 5.1 surround with OSS4 in VLC. Any help will be appreciated.
