esound and artsd is not a weird redhat thing. This from your normally
redhat bashing user. Best guess with redhats ties with KDE it is
probably artsd. Now for the lesson, check with lsof to find out what
application is using your sound card of choice. 

BTW, full duplex operation of the sound card doesn't necessarily mean
that the driver is capable of it yet. Hopefully it is, but just throwing
out a warning ahead of time.
