I skimmed through the forums, but couldn't find good answers... I'm looking for some audio device that is supported under OSx, since my current SB X-Fi isn't and the onboard AD1988B only stereo. What I need is 5.1 support with separate outs (analogue) for dem movies and some very occasional recording of a few tracks with reasonable (not Apogee) quality. Of course it should also have Win32 support (which won't be the hard part I guess), for gaming (Mic In is needed too there).

I found this one:

though shipping to germany is a bit harsh with $100

Any other recommendations?

I would wait a few days (weeks?) more.
Since Creative published an Open Source Linux Driver (32-bit and 64-bit), there may be an OSX Version soon.

I need kext for ALC888 which will display audio details in System Profiler.

Check out this Zalman 5.1 USB external sound card
http://www.amazon.com/Zalman-ZM-RSSC-Exter...d/dp/B0001OZ2K8

Do you use that one? Is it working with OSx? I have some other USB 5.1 device around (forgot make/model), that doesn't work on OSx... And nowhere where they sell the Zalman, OSx is mentioned...

According to this forum discussion it does - I hope that it's the same one!
