Nothing personal, but in the 6 years I've been on this list, that just
may well be some of the *worst* advice I've ever seen.  Let me get this
straight - the OP is using CentOS 5.3 - a distro that uses packages,
atrpms-bleeding RPM *packages*, and you're advising to switch to the
Linux kernel?  That would break more than it fixes.

ensure that the myth user has access to the contents.  It looks like
there's a sound problem, evidenced from the "Invalid CTL /dev/mixer" and
"AudioOutput Warning: Mixer attach error -2: No such file or directory
Check Mixer Name in Setup: '/dev/mixer'"
