cs46xx (Turtle Beach Santa Cruz), kernel 2.6 recording silence

System:
Slackware 9.0, upgraded to kernel 2.6.2, using devfs.

I wanted to replace my aging sbawe (which works fine with Alsa)
with a Turtle Beach Santa Cruz card.
I can play sound, but recording from Line-In does not work.
I just get silence.
The recording sw (RealProducer 8.5) uses the OSS emulation.
It finds /dev/dsp just fine, but there just seems to be no
data delivered on the device (btw, with devfs, /dev/dsp
is a symlink to /dev/sound/dsp.)

I tried using the latest drivers (1.0.2c), and the cvs version,
but no change.

There are no error logs.

Does anybody have an idea what's going on?

TIA,
- -Joe
