Hi all,
I have a K6/166 with Red Hat 5.2 installation and its 2.0.36 kernel
sound driver. Under windows 95 I can sample from external sources
with an acceptable quality. When I try to record (for instance with
wawrec) something under linus I notice a slight noise.
Seems to me that the anti alias filter remains wrongly selected.
How can I modify by hand the anti-alias cutoff filter frequency?
I think I can send an ioctl to /dev/dsp.
Mike

I have a similar problem, and was wondering whether you found a solution
already.
I have an intel AL440LX mainboard with integrated OPL3-SA3. I am using the
opl3sa2 driver from 2.2.0-pre6, which detects my card correctly. I get a loud
background noise whenever I try to record something. In win98 it works OK.
Greetings,
Ruud de Rooij.
