The linux-sound-base package ships both sets of blacklist files (for
OSS and ALSA) but, by default, only symlinks the OSS one.  Why was the
ALSA one symlinked in /etc/modprobe.d/ in your install?  Did you
modify the debconf template or dpkg-reconfigure linux-sound-base?
Either there was manual reconfiguration or a script or automated
program did something, because in a default (clean) install and in an
upgrade from Lucid, noOSS.modprobe.conf will be the (correctly)
symlinked one.

Why do you want to remove pulseaudio?  Note: "It doesn't work"
*doesn't help fix the bugs*.

Again, that symlinked module-init-tools file should not be used in a
default install.  If one chooses OSS, then one needs to be prepared to
handle those ramifications manually.  And if one didn't purposefully
choose OSS, then someone needs to take a hammer to your install.

Why would you use alsa-source instead of filing a bug against
alsa-driver?  We need to properly ship the correct drivers.  I
wouldn't say that we need to stop shipping the alsa-source package,
but it's in universe for a reason.  Further, there should not be a
reason to *ever* run alsaconf.  In fact, we're going to stop shipping
it *at all* in Ubuntu (even within alsa-source); the freezes it can
cause - and its lack of general utility - are well-documented.

Thanks for bring these issues to light.  The proper solution is always
to fix the appropriate parts of the sound stack, not to remove
