Sound failures after upgrade to KDE 3.2

I am getting sound failures now after upgrading to KDE 3.2.  I get /dev/dsp 
warnings on load and XMMS fails to pick up streams now saying the sound card 
is held by another application.

I see this is a common error but as yet all I am finding is the debug commands 
to try and no clear direction on what to change.  Thanks for any thoughts you 
can offer.

I can run KsCD and it runs fine.

On startx 
device /dev/dsp/ device busy

# sysctl -a |grep snd
hw.snd.targetirqrate: 32
hw.snd.report_soft_formats: 1
hw.snd.verbose: 1
hw.snd.unit: 0
hw.snd.maxautovchans: 0
hw.snd.pcm0.buffersize: 4096
hw.snd.pcm0.vchans: 0

Trying to start artsd manually from the konsole as su:
# artsd -lO -F10 -S4096
artsd version is 1.1.4
gsl: using Unix98 pthreads directly for mutexes and conditions
autodetecting driver:
 - toss: 4
 - null: -1
 - oss: 10
... which means we'll default to oss
Error while initializing the sound driver:
device /dev/dsp can't be opened (Device busy)

I'm running 5.1 current.  
My sound device shows as:
grep pcm /var/run/dmesg.boot
Preloaded elf module "/boot/kernel/snd_pcm.ko" at 0xc06fd350.
pcm0: <SB16 DSP 4.16> on sbc0

# ls /dev/au*
/dev/audio0.0   /dev/audio0.1
# ls /dev/ds**
/dev/dsp0.0     /dev/dspW0.0    /dev/dspr0.0
/dev/dsp0.1     /dev/dspW0.1
# ls /dev/mixer*

Running from the Konsole command line works
# cdcontrol -f /dev/acd0c play 1

it was working on XMMS and KSCD before the upgrade.

On the first boot, I got this probably unrelated failure
KNotify failed
