[gobolinux-users] /dev/dsp disappeared after upgrade

[Hi There]

One of many problems I've encountered after upgrading
to newer packages (KDE, kernel, xorg, udev) is that
sound has stopped working. I think it happened at the
KDE upgrade stage. There is no longer a /dev/dsp
present. KDE pops up a window at startup:

Error while initializing the sound driver:
device /dev/dsp can't be opened (No such file or
directory)
The sound server will continue, using the null output
device.


I thought this may have been a sound card specific
problem, so I pulled it out of my computer and enabled
the onboard sound, same error. Both sound cards worked
ok before. I have an "audio" group with proper users
as members. Correct modules seem to be loaded:

I'm using ALSA kernel modules from the kernel, and
have tried with and without alsa-oss & oss stuff
enabled.

Does udev have anything to do with /dev/dsp or
/dev/rtc? Because udev 110-r2 seems to be pretty
messed up, and I think KDE 3.5.6 depends on it.
Same error occurs with udev 105-r5 though.

If sound depends on rtc, then an error during startup
"drivers/rtc/hctosys.c unable to open rtc device
(rtc0)" may have something to do with it.

When upgrading KDE, I elected to use the new config
files, as I hadn't changed much from the old defaults.
Maybe that was the wrong choice?

]uname -a
Linux homecomputer 2.6.21.1-Gobo #4 SMP PREEMPT Sun
Jun 3 19:53:55 PDT 2007 i686 GNU/Linux

BTW, can't Compile ALSA-Driver 1.0.13-r2, it gives
kernel header file errors, looks like it's not
compatible with kernel 2.6.21.1.

Suggestions anyone?
