I have a 600E and had no end of trouble with the sound card.  I posted
questions to this list a long time ago and the one suggestion that
worked was to compile a kernel without the cs46xx driver.

It appears that the kernel insisted on loading this in preference to
other drivers and the sound hardware didn't work, even when I
blacklisted it and forcefully inserted the proper one.  I presume that
by that time the resources had been marked as used, or initialized in
some way that made them unusable.

Since I had that issue, I compiled a debian kernel (2.6.18), the debian
way with the debian tools, without the cs46xx driver, but with the cs4231
driver.  The sound card works just fine.

That's the exact one I have.

I wouldn't be surprised if the same driver (cs4231) would work on this
machine.  Maybe at least a subset of features?

Can't offer any specific help about the other problems...
