Alsa backtrace?
Every time I play an audio file using the current version of Alsa, I get a weird static sound at the end of the file. I also get this output in the terminal:

IIRC, there's a patch for Alsa with 2.6.15 floating about somewhere on the Alsa mailing lists (bad_page_state is a 2.6.15 problem, it also affects other things such as ATi's proprietary video drivers).
Apply this patch to Alsa and then rebuild.

This will be my first time to apply a patch to anything. How do I do it? Just open up that file and change the lines, or is there a special command?

Extract the alsa driver tarball. Copy the above into a text file and name it whatever you want, like alsa.patch or something. Next make sure that the patch file is in the same root directory as the driver directory and type in the following from a terminal:
patch -p0 < alsa.patch
If you are in a directory where you have rw permissions (like your home directory) you won't need to be root to do this. After you apply the patch just cd over to the alsa driver directory and do the ./configure (with whatever "switches" you need) and make. After you run make, su to root and then do make install.
HTH,

How can I delete alsa, alsa libs, and all that alsa stuff? I want to do a fresh install of alsa when I do this.

Just look for the packages you have installed:
dir /var/log/packages/alsa*
Then as root:
removepkg name-of-package
Just don't remove the alsa-driver- whatever_2.4.xx package. That's the drivers for the stock kernel. All you will need to remove will be the alsa-lib, alsa-utils and alsa-oss packages.
Also, my understanding of the 2.6.15 kernel and Slackware is you might have to replace some standard Slackware packages. IIRC, hotplug has been depreciated in favor of udev and it requires udev >= 071 (I think). You might want to check out THIS web site before you go any further. Personally I'm waiting before I upgrade till other folks sort through some of the initial problems before I switch to the 2.6.15 kernel branch.
HTH,

I'm running the 2.6.15, udev 64. alsa is running fine, everything is OK. 99% of the 'issues' with 2.6.15 are directly related to a sloppy compile.

Could anyone hook me up with the alsa patch for the 2.6.15.2 kernel? I googled all day and tried many patches, but non of them worked. All these kernel errors are getting really annoying.

Have you tried the latest 11rc3 release from ALSA. I noticed on the Changes page a few entries about the 2.6.15 kernel.
Later,
