Please run ksymoops over such a message before posting it.

ksymoops 2.4.0 on i686 2.4.20.  Options used
     -V (default)
     -k /proc/ksyms (default)
     -l /proc/modules (default)
     -o /lib/modules/2.4.20/ (default)
     -m /boot/System.map-2.4.20 (default)

Warning: You did not tell me where to find symbol information.  I will
assume that the log matches the kernel and modules that are running
right now and I'll use the default options above for symbol resolution.
If the current kernel and/or modules do not match the log, you can get
more accurate output by telling me the kernel version and where to find
map, modules, ksyms etc.  ksymoops -h explains the options.

Reading Oops report from the terminal

However, I can do "aplay /usr/share/sounds/phone.wav".
    

Please make sure that you've used exactly the same compiler version
for both the kernel and the ALSA drivers.

Yes, I did it. I compiled them in a machine.

What ALSA version are you using? (maybe try a newer one)

alsa-0.9.0rc6 and alsa-0.9.6 which is the latest one.
