Working with Context Attributes

When creating contexts, it’s listed that I can specify an int[] of attributes to be applied to a specific context like this

ALC.Context context = alc.alcCreateContext(device,attribs );

attribs is an int[] that I set up as follows:

int[] attribs = {ALC.ALC_SYNC,AL.AL_TRUE, ALC.ALC_FREQUENCY,9600};

Am I setting up the attribs array incorrectly? Is it possible that these attributes are not implemented for JOAL yet?

Thanks,

Dustin
