The other good news is that Sweex supplies the "official" datasheet from C-media which I think is quite interesting and may very well be useful to resolve the last few issues.
I'm afraid I am largely unfamiliar with USB audio but this I do find to be interesting (sweex is a cheapo Dutch brand you can grab on each street corner over here). By "supplies", do you mean you requested it specifically or did sweex just put it up on a server someplace, or something else?
The interesting part is that the IC's datasheet is actually on the CD-ROM, in the directory with manuals. The only other manual to be found there is a "joke", it is sort of a leaflet in eight languages and tells you how to "install the driver". This is how I know Sweex, Trust and similar brands.
