1. delete all soundcard related entries from /etc/sysconfig/hwconf

2. delete all sound related entries from /etc/modprobe.conf

3. shutdown and disable the onboard sound in BIOS.  I have seem boards
where this was in 2 locations in bios so check and do whatever is
needed.

4. reboot and allow kudzu to configure the "new" soundcard it sees.

5. follow all the steps that have been noted here many times for
configuring the sound/volume controls.

HTH
This will start from scratch as far as kudzu and the sound modules are
concerned.

It sounds like the drivers for both sound cards likely conflicted during
boot.
