No LFE channel (subwoofer) in Ubuntu.

[Urkle]

You might want to try posting to the OpenAL mailing list ( http://opensource.creative.com/mailman/listinfo/openal ) or ( http://opensource.creative.com/mailman/l...enal-devel ) and asking there for information about support or even how to GET support into the OpenAL drivers.

I did find this page about surround setup in linux (and makes reference to LFE). so it might help getting things working. And of course it is rather hilarious that searching for OpenAL LFE on google yields THIS forum post as the 2nd result!
