I have compiled ALSA as per BLFS -6.1 but cannot successfully execute any
commands to demonstarte the installation is correct. To more fully explain
the situation a Record of the results follows. Any suggestions for compling
or troubleshooting the problem would be appreciated.
This record is comprised of four parts:
1. The results of executing alsa "commands" after installation of linux-2.6.13
and alsa version 1.0.9.
2. The pertinent "dev" , "proc" and "etc" files
3. The configuration files for installation of linux-2.6.13 and alsa-*-1.09.
4. Audio card system information

LINUX INSTALLATION
Installation of linux-2.6.13 was done to update the kernel from linux-2.6.5.
root:/usr/src/linux-2.6.13# make mrproper
root:/usr/src/linux-2.6.13# cp ../linux-2.6.5/.config .
The existing config file was used to avoid the long process of selecting
all of the pertinent options when compiling the new kernel.
root:/usr/src/linux-2.6.13# make menuconfig
##Verified "device file" and "file system" settings.
##Exited and saved the configuration. Excerpts from the .config file follow;
