Very Computer

I bought this card knowing that all its features were not supported
under Linux, but expecting basic sound support to work, and also the
MIDI wavetable connector and joystick port to work.

When I play mp3s, I hear crackling and popping noises. I have an
es1371 Ensoniq PCI card that plays them fine, though, so I know the
problem is the card drivers, not my system.

I am running kernel 2.4.18-pre9 on a BX motherboard. I have rearranged
my PCI cards so the SC doesn't share an IRQ. I was running 2.4.17 with
the preemptible kernel patch before .18pre9, I switched to this kernel
(w/o preempt) since I noticed some cs46xx updates in there. No change.

In addition to this pop/crack problem, I cannot get either the
joystick or the MIDI daughtercard to be recognized. Didn't see any
explicit support for these in the cs46xx source code, are they
supported? Anyone gotten them to work in Linux?

Suggestions on where else to post this would also be helpful.

I have a Yamaha DB50XG wavetable daughtercard, and a InterAct PC
Arcade joystick that I want to use with the Santa Cruz card. The
joystick requires a custom option line to use all six joystick
buttons, but that works fine with the es1371.

/etc/modules.conf:

alias sound-slot-0 cs46xx
options cs46xx cs_debuglevel=9 powerdown=0
alias midi opl3
options opl3 io=0x388
pre-install cs46xx modprobe -k ac97_codec
alias char-major-13 joydev input analog
options analog js=0x00f3

Using opl3 for midi like I did for the SB16 fails:

# modprobe opl3
/lib/modules/2.4.18-pre9/kernel/drivers/sound/opl3.o: init_module: No

Hint: insmod errors can be caused by incorrect module parameters,
including invalid IO or IRQ parameters

The facts, although interesting, are irrelevant.

I have the same card and running Slackware 8.0 (Kernel 2.4.5) and KDE
2.0.  I had the same problem you had at first.  The pop/crack problem
when playing mp3s.  I use XMMS to play mp3s. Anyhow, I turned off my
aRTs sound server and toyed with the mixer settings and it ran fine.  I
only had to alter rc.modules and add /usr/sbin/modprobe cs46xx.  I
didn't have to mess with modules.conf.  THen again I don't have a midi
daughter board and am not using th midi/joystick connector.  Oh yeah, I
also had to chmod 666 some /dev files (such as /dev/mixer and other
sound related dev files) to allow sound for users other than root.

That probably didnt help much but that was all I had to do to get my
sound working.

Just WHERE do you get the daughtercard for the Santa Cruz (which might be
compatible with other soundcards that have a wavetable card header)?  I've
read so much about that expansion but never found it.
