Easiest & Safest way to downgrade udev 0.89-1(etch) to 0.56-3(sarge) (including all that depends on it) WAS Re: etch udev not working with bttv capture card nor via82xx sound?

Hello all, again.

Sorry that I keep posting to my own messages.

I could deal with no Sound for a month, but I really need them damn video
capture to work. I guess I could try to manually add the device with mknod
and then not reboot, but that is indeed a hack.

forcing the downgrade of udev will force the downgrade of hal which will
will force the downgrade of gnome-volume-manager which will force the
downgrade of gnome-desktop-environment. This is all ok if it works
properly. (My problems with gnome before were stickies always opening in
the wrong position & size, and more anoying nautalis crashing periodically
leaving me with no main menu, no desktop etc..)

What is the most painless way (using apt I hope) to downgrade my
gnome-desktop-environment and all it depends on back to sarge versions?
(most importantly udev itself)

(manually dpkg --force-downgrade for each dependancy sounds very painful)

Thanks all.

.b.

Hi again,

So after a little more digging I see that my third video capture device
(bttv) is also not working, in fact according to the kernel and dmesg it
is registered to /dev/video2, but there is no such device file.

So I bet udev is not working right, not creating the correct devices for
sound, nor for this video card.

So I guess gnome-desktop-environment depends on a new version of udev.

How can I get back my old sarge udev without breaking the other
packages?

Or fix etch udev so that it works (at least for my video capture and
sound).

Help!

Thanks,
B.

Hey all,
I'm running debian sarge (i386) with a couple unstable/testing packages
on an AMD64. I had sound working fine on my via82xx with the same
kernel
(2.6.13-ck5) under oss before upgrading gnome.
All I did today was change my gnome-desktop-environment to testing
(etch) as it was buggy with my old sarge/unstable mix of packages. I
upgraded using:
apt-get install gnome-desktop-environment
I had to manually reinstall libgconf2-4 (from etch) using dpkg to get
apt to install gnome without package errors.
Now those old bugs are gone from gnome, but now sound is no longer
working (from any application, through OSS or ALSA)
I've only changed the packages gnome directly depends on, I'm using the
very same kernel (compiled with both oss, and alsa as modules). I
installed alsa to give that a try (via apt-get install alsa-base
alsa-utils), which seems to have disabled the oss stuff (I don't see
any
oss modules in lsmod output) and I do see the appropriate alsa modules.
alsaconf finds the card and tried to configure it, all seems well
until:
bbogart@insitu:~$ sudo /usr/sbin/alsaconf
Unloading ALSA sound driver modules: snd-seq-dummy snd-seq-oss
snd-seq-midi snd-seq-midi-event snd-seq snd-via82xx snd-ac97-codec
snd-pcm-oss snd-mixer-oss snd-pcm snd-timer snd-page-alloc
snd-mpu401-uart snd-rawmidi snd-seq-device.
Building card database...
alsa finds the correct card...
Configuring snd-via82xx
Do you want to modify /etc/modprobe.d/sound
(and /etc/modprobe.conf if present)?
Yes.
OK, sound driver is configured.
Ok.
Running update-modules...
Loading driver...
Setting default volumes...
Saving the mixer setup used for this in /var/lib/alsa/asound.state.
/usr/sbin/alsactl: save_state:1163: No soundcards found...
===============================================================================
Now ALSA is ready to use.
For adjustment of volumes, use your favorite mixer.
Have a lot of fun!
So It autodetected the right soundcard, adds stuff to the modules.conf
and then can't access the device any longer.
Stopping alsa gives me:
bbogart@insitu:~$ /etc/init.d/alsa-utils stop
Shutting down ALSA...warning: 'alsactl store' failed with error message

I used the same configuration from the stock debian kernels as a
starting point for my custom ck kernel.
What got installed with gnome-desktop that killed my sound?
Any suggestions?
(Is there a debian-alsa list? I could not find one on the debian site)
Thanks all.
